SETTING UP THE MACHINE

In document MTS Turning (Page 33-43)

This chapter explains how to set up the CNC simulator for an exercise. This involves the following steps:

• Selecting a blank, blank material, the clamping device and clamping method, clamping device changes

• Assigning tools to tool turret positions and creating new tool data

• Generating the setup sheet Exercise:

A cylindrical aluminium alloy (AlMg1) blank, 80 x 122 mm is to be clamped against a back stop (18 mm) in a jaw chuck. In the setup mode menu, click on <Part / Chuck> or press to select the workpiece/clamping menu.

First select the desired material from the material table by pressing , then enter the blank geometry – a cylinder in our example. (However, material selection is not mandatory on the CNC simulator).

Select the material group Select the material and press to confirm.

Enter the dimensions of the blank in the top right-hand input fields:

• Enter the cylinder geometry data:

In filed D: enter : 80 im field L: enter : 122

To confirm your entries for the workpiece blank and register, press

Information to the material AlMg1

You have now defined the blank, the next step is to clamp it on the machine tool.

To change clamping mode, press or click left The coloured frame marks the currently selected type.

To confirm your selection, press ..

The last set-up to be used determines the currently suggested clamping method. As the current jaws only permit a maximum clamping depth of 15…16 mm, a new chuck combination must be set up on the machine.

To access the chuck menu, press .

Here again, you may change the clamping method for your workpiece. In our example, this is not necessary

To accept the selected clamping method, press to call up the chuck device library.

First select a suitable lathe chuck.

Open the lathe chuck library.

Clamping and chuck devices are stored, by name, in a special library. You can modify these in order to comply with the tooling available in the respective workshop.

Click on to select the required item in the library KFD-HS 130, then press to confirm.

Next, you must select suitable stepped jaws.

Chuck jaw selection, explanation of designations inside the name:

HM (hard alloy)

110_130 (suitatble

for the chuck and blank diameter) -02 (number of Steps in the jaw) -001 (serial number)

Press in order to select type HM-110_130-02.001

With this, you have equipped your machine tool with a new chuck with stepped jaws.

You can still make changes at any time. The other clamping devices are released in relation to the method of clamping selected before.

Press in order to install the combination on the simulator.

Of course, you can also define other chucks and stepped jaws as you wish.

Now the workpiece blank has to be clamped in the chuck.

Press in order to select the main spindle for clamping the workpiece.

Now clamp the workpiece

Press several times to move the workpiece into the chuck area.

Press to close the chuck.

Press several times to move the workpiece until it rests against the jaw stop.

Press to conclude and accept the clamping set-up.

Note:

The clamping device combination of chuck <KFD-HS 130> and jaw type <HM 110_130-02-002> can clamp workpieces with a diameter of 50 mm up to 116 mm and can grip these up to a length of 18 mm to the jaw stop.

When creating a setup sheet, this informations will be saved as header in an NC program. Open this program in the NC editor and you will see the following entry:

( ZYLINDER D080.000 L122.000.

If you use the editor to change the dimension entries e. g. to D060.000 L050.000, a blank with these dimensions will be used in the simulator the next time the program is started. If you have chosen a blank diameter which is too small or too big for the combination of chuck and jaws, e. g. D040, an error message will be generated.

Assigning tools to tool stations on the turret

The tool turret currently installed has 16 tool positions (“stations”). (You can change this in the configuration settings). Use the mouse pointer to select the turret position. The associated tool in this position is shown more largely on the screen.

You will have to mount the tools on the turret to comply with your production sheet.

T01 LEFT HANDED CORNER CUTTER CL-SCLCL-2020/L/1208 ISO30

Select position T01 and with double click open the tool library.

Press to select the tool type library.

Select tool type <Left handed corner cutter> Use the mouse to locate the tool called

<CL-SCLCL-2020/L/1208 ISO30> and select it with . This tool is then mounted on turret position T01.

In the two preceding steps, you have replaced a tool in the tool turret. To locate this tool, you have searched through a tool type for a tool with a specific name.

The tool T02 < CL-SVJCL-2020/L/1604 ISO30> ist suitable for tooling.

We will now show you an alternative method, using the tool set-up for position T03 as an example. We need a thread-cutting tool for cutting an external thread with a pitch of 1.5 mm.

Thus, the first step is to search for all tools suitable for cutting threads with a 1.5 mm pitch.

Select position T03 and then press with double click to open the tool library.

Press to select the tool type library.

Select tool type <Left handed thread cutting tool> With mouse click we select in the list field

. All left handed thread cutting tools are then ordered in the pitch parameter Pmin.

Now scroll all left handed thread cutting tools suitable for cutting threads with a 1.5 mm pitch. Select one of the two availabel tools.

Press to select and confirm the tool with the designation <TL-LHTR-2020/R/60/1.50 ISO30>. Now this tool has been mounted in position T03.

We have now shown you two different ways of selecting tools and mounting them on the turret. You can now mount the other tools of your setup sheet on your own.

You can press the tool bar button to remove an unnecessary marked tool from the turret.

The tool for position T12 of type inside recessing tool RI-GHILL-1013 L 01.10 ISO30, is currently not available in the library.

Using the tool <Management> function we will enter the respective tool data and create a new tool.

The tool management enables you to create new tool data in the individual tool types as well as to edit or delete existing tool data.

We select position T12 and select the tool

management. Press to open the tool type library.

Since a large amount of data is required, it is helpful to select an existing, similar tool to use as a template.

Mark the selected tool < RI-GHILL-1013 L/01.30 ISO30> to be processed per mouse click . Open with mouse click a context menu and select function “create”.

The selected tool is read in as a copy.

Next, select a new name for the the tolol and write the selected tool name in the entry field.

RI-GHILL-1013 L/01.10 ISO30

We select with mouse click tool parameter set cutting plate.

The new tool data can be edited in the respective parameters

You can now select with the input field.

Write the following values and enter the required data:

Broad, upper: 2.9 Broad, bottom: 3.2

.

After you have modified all required data you can now genererate the tool.

Confirm by pressing . The new tool is stored under the tool type <inside recessing tool> in the tool management. You come back to the tool type list view of the tool management.

Exit tool management with .

Now the new tool has to be assigned to position T12 on the tool turret.

We move the tool into position 12 as before

When all tools are selected for tooling, leave the tool magazine with

Now tooling is completed. Our next step is to generate a setup sheet.

In the main menu press to call up the setup form menu.

Press to generate a new setup sheet. Enter a program name e.g. <%3>.

Save with or or press to quit. The setup sheet has been created as header for the NC program.

Call up the NC Editor and open the new NC program.

If you wish you can exit the NC editor by pressing The next chapter will outline one of the methods for creating NC programs.
