USER GUIDE CONVENTIONS

Virtual DMIS is designed to run on a number of different computers and operating systems.

While many of these platforms are very similar, the look and feel from one system to the next varies enough that it is not possible to write a guide that matches exactly what the user will experience.

In an effort to present a consistent documentation that is easy to read with information that can be applied to a number of platforms the conventions described below are used.

There are four basic areas:

TYPOGRAPHICAL This is the look and feel of this guide.

KEYBOARD A description of key sequences.

VIRTUAL DMIS How this guide describes the Virtual DMIS Graphical User Interface.

MOUSE How some of the many types of mice interact with Virtual DMIS

TYPOGRAPHICAL CONVENTIONS Menu Selection

Text seen in Virtual DMIS menu selections, or titles have been placed in bold characters for its first occurrence.

DMIS Syntax

DMIS syntax is typed using uppercase lettering. When examples of code are to be presented, the font will change to a Times New Roman 10-point font.

THIS IS AN EXAMPLE OF TIMES NEW ROMAN 10 POINT UPPERCASE THAT IS USED FOR DMIS CODE.

KEYBOARD CONVENTIONS

Keyboards come in many shapes and sizes; each one has its own unique layout and labeling. In addition to confusing, labeling the function of a key can change from one application to the next. Users are urged to take a few minutes and review the notes below to learn the function of keys and key combinations in the Virtual DMIS environment.

1) The keys on your keyboard may not be labeled exactly as they are in the manual. 2) The keys on your keyboard may not be in the same location described in this manual.

Key-names

Keyboards have keys and each key has a name, a "key-name". There is a key on the right it is larger than the other keys. On many keyboards, the word "enter" is printed on top of this key. In this guide, key-names are shown in capital letters.

For example:

1) The Control key is shown as CTRL in this guide. 2) The Escape key is shown as ESC in this guide. 3) The Enter key is shown as ENTER in this guide 4) The Alternate key is shown as ALT in this guide Single Keys

Each key on a keyboard has a function and this function varies from one application to the next. The specific functions of keys in the Virtual DMIS application are listed below.

ENTER

ENTER and RETURN, are two common names for this key. Regardless of the name, these keys perform the same action in Virtual DMIS. In the documentation, 'Press ENTER' means that either ENTER or RETURN may be pressed, unless specifically instructed otherwise.

TAB

The TAB key will move the cursor from field to field within a window. Numeric Keypad Keys

On most computer systems, the keyboard is extended to include a numeric keypad on the right-hand side. These keys may be used for numeric input. The NUM LOCK key must be activated. Usually there is a light on the keyboard, indicating when NUM LOCK has been activated

ARROW KEYS (a4,0.=:>)

The arrow keys are used to manipulate the graphics on the screen. To see more information to the right of the machine, press the right arrow, etc. All four directions are available (left, right, up, down).

HOME, END, PAGE UP, PAGE DOWN

These keys may be used to move the cursor through the database area of your screen. These may be used once a program has been created

Virtual DMIS

Hot Keys

Keys can be used in combination as shortcut keys. This is commonly used in Virtual DMIS. For example:

1. ALT+P means to hold down the ALT key and while still holding down the ALT key pressing the P key.

2. ALT+SHIFT+C means to hold down the ALT and SHIFT keys and while still holding down the ALT and SHIFT keys pressing the C key

Keys can be used in sequence as shortcut keys.

1. ALT P means to press and release each of these keys in order; press the ALT key and release (often a menu bar is then highlighted) then press the P key.

2. ALT F C means to press and release each of these keys in order; press the ALT key and release (often a menu bar is highlighted at this juncture), then press the F key and release, then press the C key.

Accelerator Keys

Functions on a menu in some applications have a key-name in that function underlined. These functions can be accessed with a single keystroke when the menu is active.

Virtual DMIS supports accelerator keys for all the pull down menus on the Systems Utilities Menus. The key-name that points to the accelerator are always the keys are always the first letter or number in the name and are not underlined in Virtual DMIS.

NOTE:

When more than one item in the pull down begins with the same letter, pressing the accelerator key a second time will bring the user to the next selection with the same beginning letter. For example, the hot key ALT P will open the project menu and then pressing the accelerator, will bring the user to the Import CAD selection; pressing the key, a second time will bring the user

to Import Sensor Data. This holds true for all pull down menus.

Labels

When labels of features, sensors, tolerances, etc. are referred to in this document, the default system labels and names are assumed.

MOUSE CONVENTIONS

Virtual DMIS supports a two-button mouse, a wheel mouse or a three-button mouse. For offline use, the Logitech Magellan 3D Space Mouse TM is supported.

Wheel

LMB The left button (referred to as LMB in this manual) is the primary button. Most selections in the software are made using the LMB. Selections are made using a single 'click'.

Functions may also be performed by pressing and holding a mouse button. The movement of the mouse while a button is activated will determine the amount of change on the screen.

RMB The right mouse button (referred to as RMB in this manual) will present a variety of menus depending on where the pointer was resting when the right button was activated.

POINT Means to position the mouse pointer until the tip of the pointer rests on whatever you wish to point to on the screen.

CLICK Means to press and then immediately release the mouse button without moving the mouse. DOUBLE CLICK Means to quickly click two times. This is used to activate an application.

For example, 'Double click' on the Virtual DMIS logo to enter the software. The speed of the double click may be set by right clicking on 'My computer' on your desktop. Select open. Open the control panel on the menu and select mouse. The slider bar on the button tab will allow you to increase or decrease the speed of the 'Double click'. There is a test area next to the slider where you may test your speed.

DRAG 'Drag' means to point and then hold down the mouse button as you move the mouse

DRAG AND DROP means to point; hold the mouse button down over an item; slide the mouse across the screen and release the mouse button when the item is over the desired location.

BOX 'Box' is created by holding the LMB and dragging the pointer on the screen diagonally. This function is used in the best-fit feature construction. This feature is also used to zoom in on an area of the Graphics area of the screen.

I MPORTANT

Users installing Virtual DMIS on a network must provide Virtual DMIS with ADMINISTRATOR Privileges. The system administrator may configure the Virtual DMIS system, but a clear understanding of Virtual DMIS functionality is required. This information is available through the basic training course.

Virtual DMIS

INSTALLING VIRTUAL DMIS

Note: Virtual DMIS is installed at the factory when a CMM is shipped. If a retrofit kit was purchased, the software will be installed on the new computer that was supplied with the kit. Installation of the software should not be required.

Virtual DMIS software is protected by a License key. There are two types on license keys; one requires a parallel port and the other uses a USB port. Each License key has it's own unique serial number and a license number associated with it. Each license number is generated by the Virtual DMIS central facility. As EACH SERIAL NUMBER IS MATCHED TO A SINGLE LICENSE KEY, it is vital that in situations where there are multiple copies of Virtual DMIS, each License key remains with the system for which it was intended.

After installation ensure you have the following files backed up on a disk:

C:\winhomel\vms.ini

This file contains the password required for installation of the software and all of the tunable parameters (size, feeds and speeds, etc.) for your machine.

C:\vmshome2thin\errormap.txt

This file contains the error correction data from the laser calibration. The file name generally matches the serial number of your CMM.

For complete documentation, refer to the Virtual DMIS installation guide. 3

After a few moments, (depending on the speed and memory capacity of the computer) expect to see the following screen:

There is no User intervention required at this point. This screen illustrates normal on-line startup. NOTE:

When running on-line, Virtual DMIS operates a program that controls the CMM in real time. This program is called the motion controller driver. This background process has a number of critical tasks running all the time. When Virtual DMIS is stopped, the driver requires a few moments to complete these tasks. Do not re-start Virtual DMIS until the motion controller driver icon has closed and has left the task bar.

After a brief moment, (depending on the speed and memory capacity of the computer) a splash screen will appear. There is no User intervention required. This screen illustrates normal startup; there is no visual difference between off and on-line startup at this point.

• The user may now assign an Assembly label to the configuration and select OK.

To remove components from an assembly, select the component and select the left facing arrow in the center vertical tool bar to return the component to the list. It is also possible to "Drag and Drop" the components to assign sensor components to the sensor system.

The name (label) will automatically be entered into the ASSEMBLED SENSORS box by Virtual DMIS when OK is selected.

Deleting Assembled Sensors may be accomplished using the drop down list box of Assembled Sensors. • Select the label to delete

• LMB on the Remove key to the right of the field. • The active sensor may not be deleted.

CAUTION: Removing assembled sensors removes the assembly for all projects. If the user is unsure of the use of applications in which the probe assembly is used, DO NOT REMOVE.

Home Icon HOMING THE CMM

If this screen is displayed the CMM is ready to home.

Homing the system means to move to a preset location. This location is often referred to as the machine zero. Sending a machine to its home position allows the controller to read in the error map for the Dimensional

Measuring Equipment. The error map is a mathematical adjustment correcting any structural geometry issues electronically. The error map is a fine tune adjustment of the system.

DCC MACHINES ONLY

• Press the servo button on the

controller if you have a DCC machine. MANUAL MACHINES ONLY

• For a Manual Machine position the machine physically in the proper Home location before LMB on the home icon

HOMING THE CMM FOR ALL MACHINES

• Select the HOME icon and single click with the LMB.

The HOME icon is the little house on the right at the top of the screen. OR

• Select Tools from the system menu along the top of the screen; • Select Machine Status from the pull down menu;

• Select Machine from the pop-up window;

• Select Go Home Icon from the menu on the screen.

For more information on this procedure, go to Page 57 of this guide.

Once a CMM has been sent to the home position, the Graphics view of the CMM should coincide with the physical machine. If the Virtual DMIS software has been installed as a retrofit the graphics may not be an exact match.

If the hardware for the controller is in the computer used on the CMM, sending the CMM to home is only required when the computer has been shut down and restarted.

For systems with external controllers, the system is sent home when the controller has been powered off or if the controller has been reloaded.

Once Virtual DMIS is opened, the homing icon will automatically appear. It is not necessary to home the CMM if the emergency stop button has been engaged.

Virtual DMIS

CHOOSING COMMANDS IN VIRTUAL DMIS

Virtual DMIS commands can be executed in a number of ways: • All icons must be selected using the mouse.

• The system utilities tool bar along the top of the screen has hot keys assigned to each item

For example, 'Project' in the upper left corner of the User interface. The P indicates that ALT+ P will activate the pull down menu.

Once the menu is activated, you may move around in that menu using the arrow keys or the accelerator keys or select the required function using the mouse.

• When windows are open with an option for data entry available, you may use the TAB key to move from field to field.

To choose a menu command from the system menu, with the mouse, point to the menu name in the menu bar, LMB on the menu to activate the drop down menu. Move the mouse down to the command in the menu; LMB on the menus selection.

• If a dialog box is present, enter the additional information required.

• When all the additional data has been entered, or all of the selections made, click the appropriate button to complete the execution of the command. In most cases, clicking the OK button will complete the task. Usually, a CANCEL button is available. Pressing CANCEL will quit the execution without saving any of the changes made. • Selecting

El

in the upper right hand corner of an active window will close the

window.

Pop-up menus are available in many areas. A right mouse click (RMB) will display the pop up menu.

INTERACTIVE LOGO & DRIVER STATUS ICON

The upper right hand corner of the screen displays several informational icons that define machine and controller status.

The conditions and required actions associated with each Icon are described below. HOME:

This Icon indicates the machine needs to be "Homed". (See Glossary) VIRTUAL DMIS LOGO:

When the system is ready for operation, the 3V DMIS logo is seen with a ball cycling along the "V" and the Driver Status Icon is green.

When a program is executing or when an error occurs this Icon is replaced with one of the following Icons.

DRIVER STATUS ICON:

The driver status icon is a round light that may be present in one of five conditions. 1. The driver status is Flashing and GREEN when, the CMM is on-line with Virtual

DMIS.

2. The driver status is GREEN and not flashing when the system is performing a task that requires time, for example computing the profile of a curve or surface.

3. The Driver Status Icon is not displayed for OFF-LINE Virtual DMIS installations. 4. The driver status is GREEN / RED when, Virtual DMIS is in Simulation Mode.

Simulation mode will disengage the motors of he CMM and part programs may be run in an offline mode without logging out of the online software. Program simulation allows the user to run the program and watch the probe path on the screen.

5. The driver status is RED when some aspect of the CMM is functioning correctly. PROGRAM EXECUTION:

During program execution, when a feature is being measured, this icon replaces the Virtual DMIS logo.

SERVO'S OFF:

When the servos are off, this icon will appear; the button switch shown in the icon will appear green.

EMERGENCY STOP:

When the emergency stop button is activated, this icon will appear. The Driver status light will change from its normal state, green, to red. In addition, if the E-Stop is depressed, the button will change to red.

LOW AIR PRESSURE:

When this Icon is displayed, the machine must not be moved! Determine why there is insufficient air available to the machine, remedy the problem and the low air Icon will be replaced by the Virtual DMIS logo.

Virtual DMIS

OUTSIDE OF ERROR MAP ON X-AXIS:

Probe position is outside of the X error map range. This could affect the results

of the measurement. This icon can appear if the user attempts to measure features without first sending the CMM to the home position.

OUTSIDE OF ERROR MAP ON Y-AXIS:

Probe position is outside of the Y error map range. This could affect the results of the measurement. This icon can appear if the user attempts to measure features without first sending the CMM to the home position. OUTSIDE OF ERROR MAP IN Z AXIS

Probe position is outside of the Z error map range. This could affect the results of the measurement. This icon can appear if the user attempts to measure features without first sending the CMM to the home position.

MISSING ERROR COMPENSATION FILE:

This indicates that there is no error compensation available on the system or that the error compensation file location and the VMS.INI file entry for the error compensation file do not match.

SCALE ERROR:

This indicates that there is scale read error. This may also appear if the ON Motion Servo motors are not ready.

This is used on systems with analogue reader heads. If it appears it indicates a scale read error on the reader head as well as the machine.

TCPIP

This logo indicates a TCPIP connection is active. Typically, this appears while working on a dual arm CMM.

Virtual DMIS CAD Translation

Virtual DMIS supports several neutral file formats; IGES, STEP, and VDA. These files are translated into two files, a WRL (VRML) file used for display and an RLE file used to store mathematical data. VRML and IV files do not require translation.

If an IGES file is translated, the file name remains the same and an extension is added to the end of the file name once the translation is complete.

Example - SAMPLE.IGS will be converted to SAMPLE.IGS.WRL and. SAMPLE.IGS.RLE. While a file is translating, it is possible to continue working within Virtual DMIS. The translator may be run in the background.

The CAD Translator Shortcut is automatically placed on the desktop when Virtual DMIS is installed. If the short cuts are not on the desktop. The *.exe

Visual Tolerance

Entity Filtering

This setting only affects the .WRL file by changing the number of triangles for each face. The larger the Visual tolerance setting, the fewer triangles

involved in the graphical view, resulting in a smaller WRL file. If the translated file is too large or difficult to manipulate in Virtual DMIS, the visual tolerance value may be increased and the file translated a second time. A lower visual tolerance may fill gaps in surface data that appear at a higher Visual Tolerance value.

Select the entities to include or exclude by checking the appropriate boxes.

Mirror Plane Sets the plane to mirror about if a mirrored part is desired Virtual DMIS requires the CAD files are stored on the local computer for translation. Translation of files stored on a network drive may be slow and the translated files may be corrupted.

A log file will record the options selected for the translation. The log file name is the combined with CAD file name. For example, the log file for IMS Block Surface.igs will be "IMS Block Surfaceigs.translator_options.log". The file will be created in the folder containing the CAD file.

IMPORT SENSOR DATA

Imports previously defined sensors from existing projects. If sensors were calibrated in the existing project, they will be available under the actual sensor list. If the sensors were not calibrated, they will appear only under the nominal sensor list.

It is important to note that sensors brought into a project in this manner do not get included in the definition of the sensors in the DMIS program. The code will be written to change to the various sensors and as long as the sensors are in the sensor database, the program will run. However, If the DMIS program is to be transported to a different CMM, or the programmer plans on using the Virtual DMIS Simplified User Interface (SUI 4), it is important that the code to import the sensor database is written to the part program. 5

Caution: If any sensor data is defined prior to importing sensor data, it will be overwritten without warning.

IMPORT COORDINATE SYSTEM

Imports previously defined coordinate systems from existing projects. If any labels are duplicated, the existing coordinate system will be renamed. Files are renamed as follows: coordinate system being imported has the label PCS1 and that label is present, the existing label is renamed to PCS1_2.

Coordinate systems may be recalled into a DMIS program in the same manner as sensors.

IMPORT TOLERANCE DATA

This will import previously defined tolerance data.

When a program is created and tolerancing is defined, the tolerance data is stored in the 'Vol' directory associated with that project name. If the parts to be programmed use general tolerances, it is possible to set up one tolerance file with these general tolerances defined. The program would call up this

tolerance file using the 'IMPORT TOLERANCE DATA' command.

Once tolerance data has been imported, the User will not be required to type in any tolerance information. To apply a tolerance drag and drop tolerance information from the tolerance database into any open tolerance window.

When importing tolerance data containing DIAM and CORTOL data, the current settings will be overwritten and the imported values will become the default. If the imported tolerance data does not contain these two tolerance types, the current default values remain active.

Here is an example of recalling data from a stored project

Recalled sensor data, named coordinate systems or tolerance labels are stored by project name. Because the data is stored by project name, the recall screens appear identical, however only the requested data will be input.

IMPORT FEATURES

This will import previously saved project features.

An example of application would be to set up a fixture in one project and measure a part in a second. If the user required a tolerance between a fixture feature and a part feature, it would be necessary to import the feature data from the fixture project.

IMPORT DMIS

IMPORT OTHER LANGUAGES

Available in Off-Line only, this function allows the import of other OEM programming languages.

The languages available are:

1) ACCUDAT 2) AVAIL 3) TUTOR 4) MASTER 5) CMEAS

Virtual DMIS will translate the above languages into the standard DMIS syntax, allowing projects writhen using various OEM CMM programming languages to be run on a Virtual DMIS system.

EXPORT CAD

The purpose of this key is to take the geometry data created during an inspection and translate the data to IGES format. This allows the CMM to become a part of the design process by accommodating reverse engineering.

Virtual DMIS exports all features as B-Spline lines and points. Accelerator — E

This function is reserved for future use.

RECENT PROJECT FILES

The "Recent Project Files" keeps a list of the last 4 Projects the user has been working on. The 1 st entry in this list is a Backup project that Virtual DMIS automatically creates. This allows for instant Data recovery should the system shut down due to any unforeseen reason (crash). At Virtual DMIS start up, after a previous session crash, will generate a Question window to ask whether one wants to reload the temporary project saved from the previous session.

The 2nd through the 4th entry are projects previously worked on. By selecting the desired entry, Virtual DMIS will load all data that belongs to that project, allowing for very quick switching between different projects

EXIT VIRTUAL DMIS

The exit command will close the Virtual DMIS window and prompt the User to save the current project. Once the window is closed, any data that was not saved is lost. Click on the line 'Exit Virtual DMIS', and a file management screen will appear. If you would like to save the current project, type in a name on the line titled File name. All files saved in this area will have the extension `.prj' added automatically.

Virtual DMIS will prompt users to save the current project ONLY if the current project has changed since the last save.

With learn on the DECPL command is output. "DIST", distance, includes actual and nominal features and all linear parameters including size.

ANGLE, all angular parameters DEV, covers tolerances and deviations VEC, controls the number of decimal places output for vectors

You may change the default value for any group by using the down arrow to select the desired group and then the down arrow to the right of the numeric window. This will bring up a list of numbers below the default value from one to ten. Click on the value of your choice to change the setting. The drop town list provides up to 10 decimal places for significant digits. Please remember the accuracy on your CMM. 2 significant digits when using millimeters and 3 when working in Imperial units are typical. Some programmers may increase these by 1 (3 in millimeters and 4 in inches). Remember the capability of y our CMM when setting these parameters.

Video last frame pause - Allows the user to determine how long the help video will remain on the screen once it has completed running. A setting of '1000' will keep the picture for one second, where a setting of 10,000 will keep the picture for ten seconds. This setting is stored in the VMS.INI 6 file.

Whisker Magnification - Graphics display will display form error whiskers for a measured feature when it is dragged and dropped on the graphic area. Form errors will not be displayed for constructed or nominal features. The size of the whisker is a reflection of the error and the whisker magnification. This value is read at start up from the VMS.ini file and is stored to the file when Virtual DMIS is exited properly. The sizes of the whiskers are a combination of the view arrangement and the actual form error on the feature. While displaying form error graphically, the user may zoom in on the feature so that it is the only item on the screen. If that is the case, the whiskers may have a smaller value in the setup as opposed to the size required for the complete view of the part. Remember while displaying form graphically that the error on a feature will change from one part to the next. The whisker magnification may need constant adjustment.

This dialogue box is used to prevent hitting the shank of the probe during calibration. These parameters are of particular interest when calibrating styli with very small ruby tips or if the angle of inclination is greater than ninety degrees.

The sphere-bounding vector is also used to define the orientation of the mounting stem for the calibration artifact. Stem may be referred to as Stalk by some users If the stem of the

calibration artifact is not orthogonal to the CMM surface this vector must be updated to provide the capability of automatic sphere measurement.

Note:

These settings will affect the probe path available if Automatic Sphere measure is to be used during a part program

For systems using the Renishaw TM UCC controllers, the sphere-bounding vector is defined in the VMS.ini file under the [RENISHAW] section of the file. The vector stored in the VMS.INI file is required by the UCC controller for use of the analogue scanning heads. The sensor calibration routine for the scanning heads is a function of the controller, NOT Virtual DMIS. Sphere bounding vector This defines how the MGAGE (calibration artifact) has been mounted on the CMM table.

If a standard artifact is being used, the vector will be 0.00, 0.00, -1.00. Specifically the vector defines a plane that intersects the calibration sphere at the equator with the vector of the plane aimed into the mounting stem.

Sphere bounding ratio This value is used to avoid collisions with the stem of the qualification artifact.

The value defines what percentage of the sphere is available above the bounding plane to the automatic calibration routine (in this case above means in the direction of the plane vector). In order to clear the mounting stem while calibrating a star tip or a sensor with an angle of inclination greater than ninety degrees, the system is installed using a sphere bounding ratio of 67%. A larger the mounting stem requires a larger value entered into the window. In the diagram on the following page, the Bounding ratio removes approximately 33% of the sphere surface that is available to the probe. The image above indicates a sphere-bounding ratio of 63% (100%-37%). If the stem were larger, the value entered into the window would be smaller.

Sphere bounding dist. This value is used to prevent hitting the shank of the probe when

calibrating styli with small diameter tips. A secondary plane is defined X-distance below the bounding plane (in this case below means in the opposite direction of the plane vector) The area between the bounding plane and the offset plane is no longer available to the sensor for calibration. The vector of this plane is orthogonal to the active sensor and is updated with each sensor selection. Hence, once the plane is defined the sensor may be safely calibrated in any position.

Comment out all sensor definition during create This option prevents errors in the sensor calibration status. As a program is created, in learn mode, the definition line for the sensors is commented out to prevent overwriting calibrated sensors during the re-running of a part program.

Sensor definition lines are required if the DMIS code is to be run without loading the full project. If this is the case, the user must calibrate the sensor immediately after

definition for a calibrated sensor to be used in a program.

However if the user is running a Virtual DMIS PROJECT the sensor database is

automatically loaded into the project, and the user may choose to calibrate or not depending on the status of the probes. When running a program with sensor definitions commented out, Virtual DMIS automatically looks for the appropriate sensor in the sensor database. If the sensor database was not loaded, (in the case of Import DMIS) the sensors would not be present and the definition would be required.
