ATA

The configuration of the multitorch of the selected machine appears in the present window.

• Number of torches: It shows and allows configuring the number of torches of the machine. The system supports to use up to 20 torches at the same time.

• Torch capabilities: Each torch may have different capabilities for cut, mark or for machine chamfers or notches. In this dialogue box, the user can choose the capabilities of each torch.

Figure 1: Torches table

In the example, the first torch can be used for all kinds of machines, but the second, third or the fourth can only be used for normal cut.

• Torches on axis Y: Depending on each machine, the torches can be placed on X axis (by default), or in Y axis. It is important to specify to system which kind of torches placement the machine uses. • Control Torch: It establishes the reference torch. The CNC program is built for this torch and the

(32)

32

the torches are on axis X, the possible movements are Right and Left. If the torches are on axis Y, the possible movements are Up and Down.

• Minimal distance between torches: This is the minimum distance allowed between two torches. • Maximal and distance between torches: This is the maximum distance allowed between two

torches.

• View configuration in "Do all": The multitorch configuration is shown each time the user clicks "Do All" option in the Nesting module, which makes the nesting and machining process automatically for all jobs depending on the configurations of Automatic Nesting and Automatic Machining. This dialogue box is shown when you use Sheets -> Multitorch too.

In the dialogue box, the list of torches along with the capabilities and distances of each torch is displayed:

The capabilities of each torch are shown with icons:

You can activate the torches you would like to use. If the icon near the number is in red color ( ), the system can use that torch. The user can deactivate torch by clicking this icon. The icon is turned to black color ( ). Click the black colored icon to activate the torch again.

• Rotate parts according to multitorch: Select this option to allow the system to rotate parts while using multitorch.

• Positioning: When you click this button, Torches positions dialogue box with following parameters is displayed:

o Test this data before machining: Select this to test the possibility of doing multitorch cutting by position when the system detects multitorch cutting. The system verifies if the

(33)

33 torches can reach the specified position before performing the machining or not. If the

part is not correct, then the system exploits the part and its corresponding multitorch parts.

o Index of the reference torch: The reference torch is the torch with the motor, and the rest of them depend on this torch. You can set the index of the master torch here.

o Initial position of the reference torch: The reference torch is fixed in the carriage. It can't be moved. You can set the position of the reference torch with the value that you enter here.

o Minimal position of torches with respect to zero point of the carriage: The rest of the torches (other than the reference torch) can be placed along the carriage but they must keep some distance from the reference torch. The nearest to the reference torch can be placed at the distance specified here. The distance is referred to the zero point of the torch.

o Maximal position of torches with respect to zero point of the carriage: The maximal position along the carriage where the farthest torch to the reference torch can be placed. The distance is referred to the zero point of the torch.

o Maximum length that can move to negative the zero of the carriage: The carriage can be placed in different positions between the physical limits. This value is the maximum length to which the zero point of the carriage can be moved towards negative direction. o Maximum length that can move to positive the zero of the carriage: It is the maximum

distance to which the zero point of the carriage can be moved towards positive direction. o Co-ordinates of the zero of the carriage respect the zero of the sheet: This value is the

distance between the zero point of the sheet and the zero point of the carriage. If the reference torch is placed in the middle of the carriage, and the sheet is placed in the work zone, this is the distance between the reference torch and the zero point of the sheet. o Torch movement length: Select whether the torch movement length should be

independent of the separation (the distance between two torches) or depend on that.  Independent of the separation: It allows cutting parts even when any of the torches is

out of its “Maximal position of the torches with respect to the zero point of the carriage”.

(34)

34

 Dependent of the separation: If any of the torches is out of its “Maximal position of the torches respect of the zero point of the carriage”, the parts are not cut (even if the part keeps the minimum distance with the previous one).

o Assignation of the dimensions of the contour:

-By Contours: The system decides, depending on the carriage limits, which torches to use for machining problematic contours.

-By Parts: The part is always machined with the same torch (interior and exterior contours).

2.2 G

RID

This is used for cutting machines that have a work support grid. It is possible to specify the visualization parameters for the support grid. It is not typically required for punching applications.

• The machine has grid: First of all, the user must check this option for enabling the rest of grid configuration parameters:

• Visualize: Select this check box to simulate the grid. You can also see the positions of the parts and modify them, if required.

The parameters to configure are 2D Points and Continuous Line/Arc.

o X and Y: the coordinates of the first point.

o d1 and d2: the horizontal and vertical distances between points respectively. o n1 and n2: the number of horizontal and vertical points respectively.

(35)

35 The other parameter to configure is File. You have the option to define the grid with your own parameters

in MEC format. The grid in MEC format with the desired geometry can be imported to the system. Select File check box if you want to import your MEC file. You can use the Navigation button to select the particular MEC file.

• Parameters for destroying holes: This option is for cutting or combination machines with grid. The system executes a process for destroying the holes on the sheet. The sheet is placed over the table's grid. Depending on the distance of the grid's lines, sometimes while cutting a hole, it may remain on the table instead of falling down. If it remains in horizontal position there is no problem, but if it inclines between two grid lines, it may stand out and the head can collide with it resulting in head damage.

To prevent this, the system provides the option of cutting the holes into small parts to ensure they always fall down the grid.

The following four parameters delimit the size of the holes to be destroyed:

o Maximum length of the hole o Minimum length of the hole o Maximum width of the hole o Minimum width of the hole

The following example explains how to use this option. In the nesting, there are some parts with big holes. The grid lines are shown in violet color:

(36)

36

The hole of the upper-left part is bigger than the values given (X:150-450, Y:150-450), and the smaller holes are not between the defined lengths and widths.

So, if you execute the order for destroying the holes from the CAM module before doing the machining in Machining -> Contours -> Destroy sheet holes, it asks for confirmation of previously entered data, and also the length and the width of the grid lines.

Figure 2: Configure: Machine window

The system calculates and introduces the required machining orders, which destroy the problematic holes:

(37)

37 Figure 3: Problematic holes example

The big hole of the part is too big and stays over the grid without problems, and the other holes are too small fall into the table without problems.

• Automatic micro-joints in unstable contours: It is possible to configure automatic micro-joints. The user will be provided with the following options:

o No: Do not place any micro-joint.

o The part has no support on the grid: The micro-joints are only placed. on parts without grid anchorage.

o The part can be partially overturned: The part may finish partially overturned. o Both: Both previous options will be selected.

LAMPS

2.3.1 Position

• Number of clamps: You can select the number of clamps from the drop down list. • Positioning: You can set up the positions of the clamps in this section.

o Any: If you select this, the clamps can be placed anywhere. This option is used for machines whose clamps must be placed manually with screws.

(38)

38

o Fixed: When the clamps are placed into the linear turret, they take positions with fixed distance increments between them. In this case, the position of the clamps can be configured easily with the following parameters:

• First position variable: Although the turret has fixed positions, if you select this, the first clamp site can be in different position each time, and the rest of the clamps are placed after it.

• First position: The distance between the first clamp position and the reference point. From this first position, the rest of the clamps are placed as per the next two parameters:

• Number of positions: Total number of positions of the linear turret.

• Position distance: Distance between each turret position. The system calculates every clamp position adding to the first position the value given here.

For example:

Figure 4: Sheet clamps position distance example

• Positions: Positions indicate the distance between different clamp positions.

(39)

39 o Left sheet: The reference point is the left side of the sheet.

o Right sheet: The reference point is the right side of the sheet. o Left work zone: The left side of the work zone is the reference point. o Right work zone: The right side of the work zone is the reference point.

• Place the clamps with the mouse: This is used frequently when the user works with the whole sheet without using lower sheet margin. In this case, it is normal to have parts or holes to avoid, and this is difficult, if the clamp placement was done inserting distances with the keyboard. But if the placement is done with the mouse, you can slide the clamps and place them in a position which allows machining the whole part of the sheet. With this, you can avoid reposition orders.

The system prompts to place the clamps with the mouse when the Machining -> Initialize order is selected.

• Prompt for this data when initializing: If you select this option, the system shows the Sheet Clamps - Position dialogue box when the initialization instruction is executed. Please refer Machining -> Initialize.

• Offset: The offset is the minimum distance where the clamp can be placed from the side of the sheet. For example, if the value is 70mm, and the clamp is to be placed at 40 mm, the system places it at 70 mm. The clamp must have a sensor for executing this.

(40)

40

• More: When you click More button, a dialog box is displayed, where you can configure each clamp's properties like 'Minimum position', 'Maximum position', 'Minimum distance’, and 'Maximum distance’. You can indicate whether the clamp has sensor or not. You can also select the 'Type' of the clamp from the drop down list. The options available in the drop down list are 'Fixed', 'Movable', 'Auto-retractable', and 'Movable - 2positions'. If you select 'Movable - 2positions', 'Distance' field is activated, and you can define the distance the clamps can move.

2.3.2 Clamp Zone

• Clamp Zone: You can set up the measurements of the clamp zone.

Clamp Size: The clamps size can be set up here based on the three parameters: L, R, and U. These

settings configure the real clamps size, which are used for the automatic repositions. The system tests if the clamp is to be placed in a hole or not. If the clamp is to be placed in a hole, the clamp cannot take the sheet properly.

Simulation: If you click the Simulation button, a dialog box is displayed. The system simulates the

(41)

41 Figure 5: Clamp zone simulation

• Offset of clamps zone: If you click the Offset of clamps zone button, a dialog box is displayed. You can add the safety distance required to the clamp's work zone.

• Prompt for this data when initializing: If you select this option, the system shows the Sheet Clamps - Clamp zone dialogue box when the initialization instruction is executed. Please refer Machining -> Initialize.

2.3.3 Auxiliary

You can configure the auxiliar details of the clamps here.

• Move from point interactively: Select this checkbox to change the “From point” of the machining. • The clamps take up turret position: With this option the clamps are placed in the turret.

• Maximum length of the sheet to enable the pin 2 automatically: Enter the required value to enable the pin2 automatically.

• Initial Offset of the work zone: Enter the Initial Offset value of the work zone. • Offset to avoid the clamps: Enter the offset value for the punch to avoid the clamps.

(42)

42

• Pin 2: Select this checkbox to activate the minimum length of the sheet, clicking on navigation button. The user can configure Move from point interactively.

• Allow collision test for clamps: Select this checkbox to allow collision test. • Apply clamp check: Select this checkbox to apply clamp check.

• Prompt for this data when initializing: If you select this option, the system shows the Sheet Clamps - Auxiliar dialogue box when the initialization instruction is executed. Refer Machining -> Initialize.

IXTURES

With this option you can configure the fixtures or the fixed clamps of the machine. The fixed clamps work similar to the clamps. The machine will only have clamps or fixed clamps, they will never be together in the same machine. To configure the fixed clamps the clamps number must be 0 otherwise the “Fixtures” option will not be displayed. If after configure the fixed clamps, the user modifies the number of clamps bigger than 0, the fixed clamps parameters will be avoided.

During the machining initialization, it is possible to configure the fixed clamps with the keyboard and with the mouse. The changes made during the initialization with the keyboard (using the configuration panel) will be saved as standard in machine configuration parameters.

• Positions

o Number of fixtures: The clamps can be located in any position. This option is used for machines whose clamps can be placed automatically.

(43)

43 Figure 6: Fixtures dialog box

• Fixture zone: When the machine is initialized, this is the clamp zone which the system will use before starting the machining.

• Place the fixtures with the mouse: This is used frequently when the user is working with the whole sheet without using lower sheet margin. In this case, is normal to have parts or holes to avoid, and this is difficult if the clamp placement was done inserting distances with the keyboard. But if the placement is done with the mouse, the user can slide the clamps and place them in a correct position which allows to machining the most part of the sheet. The user can avoid reposition orders thanks to this option.

• Prompt for this data when initializing: The machine initialization process must be done always before making any machine instruction. With this option enabled, the system will show the Clamps dialog always when the initialization instruction is executed.

HUTES

There are three options for removing cut parts: Part Extraction (traps), Micro-joints and Stop codes.

Part Extraction is used for cutting machines with clamps to fix the sheet, because in these machines the sheet moves and the parts must be evacuated. If the cutting head moves alone on the sheet, there is no need to evacuate the parts and the traps configuration is not required.

• Number of traps: The user can configure here the number of traps of the machine. Depending on this number, the system shows the boxes needed to specify the respective coordinates (all the distances are referred to the cutting/punching center):

o Minimum X & Minimum Y: These are the coordinates for the lower left corner of the trap. o Maximum X & Maximum Y: Coordinates for the upper-right corner of the trap.

o Increment X & Increment Y: The machine makes one movement after receiving one trap open instruction while trying to center the part into the trap. This increment of movement is configured here.

• The machine has an extraction hammer: If the machine has an extraction hammer and extraction hammer2, these must be configured here. This hammer is used to hit the trap to make sure it opens properly. The hammer is defined by the coordinates X and Y and the radius.

• Extraction hammer 2: Here you can specify the X, Y coordinates and the radius of extraction hammer 2.

General

• Retract value in Y: This is the back off distance in Y when opening the clamps. It is applied before the X carriage is moved providing a clearance between the clamps and the edge of the sheet.

• Advance value in Y: This is the value that the Y axis moves back after repositioning. Normally is the same as retract value, but sometimes is smaller to prevent the sheet being "nudged" by the work clamps if the edge of the sheet is uneven.

• Speed in X: Defines the feed rate in X of the machine when moving the sheet during repositioning. • Speed in Y: The feed rate applied to the back off move.

• Fixed value of repositions and value: With this option enabled, the user can specify the distance to move in a reposition. If this value is bigger than the work zone, the system will not do any reposition. • X position of reposition: Using this parameter the user is allowed to define the sheet fixture point

during the automatic repositions. It is only valid when the sheet is fixed by the head or the pistons.

This parameter has the following two options:

- Fit to the edge of active work zone.

- Sheet center

• Test for sheet clamps in holes when repositioning: When doing repositions, sometimes the clamps are placed inside holes resulting in a bad sheet catch. With this parameter enabled, the system will test each clamp position before placing it on the sheet. The distance increment for testing must be set up in Increment of search of correct position option.

(48)

The system will not allow reposition movements if there is not a Minimum number of clamps catching the sheet properly.

• Look for a correct Y position of reposition: The system will check for an appropriate position of the Y axis. It is important to hold the sheet strongly while the clamps are relocated, for this, the pistons must be in contact with the sheet and not placed over a previously cut hole.

If the user configures upper and lower margin and an increment, the system will scan between these limits for a valid position, altering the Y value each time by the stated until a suitable position is found.

• Maximum number of reposition & Maximum increment of reposition: The user can specify the number repositions to do while machining and the maximum length for any reposition. The machining will be stopped after reaching the number in maximum number of reposition instead of making more repositions. Once the reposition type and all the parameters are configured, the user can choose two reposition strategies clicking on Strategy button.

• Sheet hold mode when displacing movable clamps: Using this option the user can fit the sheet with the turret head of with the pistons while moving clamps. The user can select between: No hold and Pistons.

• Y minimum position: This configuration parameter, which defines Y minimum position, avoids or shows a warning when the user executes a manual reposition below this Y. the user will be able to select between: No, Avoid and Ask.

2.10.3

Device

• Type of reposition: There are three different types of repositions: with Pistons, using Head or both of them.

• Number of pistons: If pistons are selected in the previous parameter, the user will be able to introduce the required number of pistons.

• Remnant margin: When a remnant is generated from the current sheet, if there is any value here, the remnant will be created with these margins.

• Respect sheet margins on remnants: This dialogue allows you to specify margins around the sheet. This ensures the machine is not going to cut or punch out of the sheet and leave enough material to support the parts. In the example shown, the lower margin is larger to avoid the clamp zone. The X and Y values are the coordinates that the system will take for the selected red point. Normally this point is the 0,0 because it is the point where the torch will be placed before cutting. • Display sheet reference in status bar: If this parameter is activated, the reference of the sheet will

be displayed in the status area while working on the Nesting.

• Sheet state: Indicate the fold status of the sheet through one of the numbers in the list. (0 = completely flat, 9 = very irregular). This parameter may be useful if the postprocessor uses it to calculate the distance that the head must come down in order to cut/punch for trying to avoid collisions with sheet.

• Anti-scratch: This parameter's objective is that the rapid movements are done at a higher distance for not scratching the sheet. When the movement is from one hole to another with the head down, instead of the normal height, with this enabled it will go a little higher.

• Rotation: With this option the user can visualize the sheet rotated 900

, 1800, and 2700

• Minimum length and width: Using this parameters the user can limit the minimum size (dimensions) of a sheet.

. It also allows making sheet symmetry around the X or Y axis. This parameter is not configurable through the system yet. You can configure it modifying the parameter A266 of the selected machine CT file.

51 • Previous position point to turn over: The user can select between the following options:

o Request: Allows the user to select the previous position point to turn over.

o Fixed point on the sheet: The user can specify the Fixed point in X and Y direction. o From point: The user can specify the Displacements in X and Y direction.

o Lower left corner of the sheet: The user can specify the Displacements in X and Y direction.

o Lower right corner of the sheet: The user can specify the Displacements in X and Y direction.

o Upper left corner of the sheet: The user can specify the Displacements in X and Y direction.

o Upper right corner of the sheet: The user can specify the Displacements in X and Y direction.

o Sheet center: The user can specify the Displacements in X and Y direction.

• Cancel repositions when executing the turn over: Using this option the user can cancel reposition. If there were any reposition before the sheet turnover, after executing it, all the reposition will be cancelled keeping the working zone as it was at the beginning.

o 5 Axis: In this, you can define two angles to rotate head part depending upon the type of head that you have selected.

a) If you select Type A the AB corresponds to X axis and CC to Z axis.

b) If you select Type B the AB corresponds to Y axis and CC to Z axis.

c) If you select Others then the AB and CC correspond to the axis that you indicate.

o Tangential: Using this option you can rotate the head only over one axis, and can also define the maximum and the minimum angle of the rotation.

o Tangential 5X: This option is the same as 5 axis with a tangential sensor that measure the height of the sheet, because of that the head can cut only in one direction.

2.13.2

Chamfers Management

• Type of cut: Depending on the type of cut, three different options are specified:

o

o Group by same type: This option allows you to join the edges with the same kind of chamfer (For example: triple with triple, double with double…).

By elements: Using this option, you can cut the edges of the part separately (Finish all the cut of a segment before beginning with the next one).

o Group by same angle: In this option you to join the consecutive edges with the same type of angle (For example: upper with upper, lower with lower ...).

• Machining dimensions on nesting: The machining dimensions on nesting are divided in three ways:

o No: If this option is selected the machine will not take care of the inclined cuts to nest the parts.

o Yes: If this option is selected the machine takes cares of the cutting point of the part both in the upper size or in the lower size.

o Orthogonal: If this option is selected then the machine uses the further cutting point of the part, only in the upper size.
