Designing & Defining Special Tools & Cluster Arrays

A special tool is any tool configured of a non-standard shape. A non-standard shape indicates the tool is something other than a round, obround, rectangle, square, single D, double-D, four-way radius, triangle, or rounded corner rectangle.

Options on the Tool Assign tab > Special Tool submenu allow you to create and manage special tools quickly and easily. Once you create a special or cluster tool and add it to a tool inventory, you can use the Place Tool Hits option on the Group Pattern submenu (Draw menu) to position the custom pattern on your part.

You can use the Define Special Tool and Define Cluster Tool Array options on the Special Tool submenu to create special tools and then assign those special tools to identical cluster patterns.

Designing a Special Tool

   

To draw a special tool, select Design Special Tool from the Special Tool submenu to open the Special Tool Designer window. The window displays a circle having a reference point at its center, and the Special Tool Information window. The circle represents the actual tool size. If you modify the Tool Size value, the circle resizes accordingly only after you place patterns within it. The Tool Size parameter is saved with the special tool.

Note: The system automatically begins a new special tool each time you start the Special Tool application.

Note: When defining a Special Tool and assigning tools, AP100US can snap not only to the default point, but also to an additional point placed by the user.

Note: Changes saved to a Special Tool in the Special Tool Designer module will automatically be passed to the Tool Inventory.

The Draw/Edit/Macros and Dimension menus function as they do in AP100US.

 

 

 

If the Special Tool properties window is not open, click the Amada "A" to open the main Special Tool menu.

Click on Special Tool info as shown in the image.

 

 

 

 

Special Tool Properties Window

   

 

 

 

Use the Special Tool properties window to define the tool. The window disappears if you select another option. Open the window by selecting Special Tool Info in the menu bar. You can draw the tool after you have typed all the values.

When defining a special tool, the system should use the overall X and Y values of the Define box and transfer them to the X and Y values in the Dimension fields. This will at least give the user the overall size of the tool.

Notes on snapping to points:

The point or pattern in the Shape Definition can be used as the Center of the Tool.

Actual coordinates can be entered in the Coordinates panel when placing a snap point on a special tool. It's also possible to manually place a snap point by selecting Draw>Point and then clicking on the part and editing coordinates in the Pattern Properties panel that displays on the right side of the work area.

 

Note: When a Special Tool is edited here in the Special Tools Designer, changes made will automatically be updated to the Tool Inventory.

Description

General Info

 

Station Size

Type the station size required for the tool.

Tool Size

Type the size of the work area required to draw the special tool. You want to specify the Tool Size before drawing the tool. The value loads with the tool and determines the size of the work area.

Dimension

You can record an X and Y dimension (X is the smaller dimension; Y is the larger) for the tool.

X

Type the X dimension for the tool.

Y

Type the Y dimension for the tool.

Symmetrical

There are three options you can select from the drop-down list: None, Square and Rectangle. You can specify whether the tool reacts to angles like a square or rectangular tool.

None

No symmetrical setting.

Square

If you select Square, you could assign the tool to patterns having the same direction, but at different angles. For example, 0°, 90°, 180° and 270° would be the same direction to a square tool. As long as the special tool is in the turret at one of specified angles, it can also be assigned to any other special tool that was at 90° intervals.

Rectangle

If you select Rectangle, you could assign the tool to patterns having the same direction, but at different angles. For example: 0° and 180° would be the same direction, as would 90° or 270°.

Keyed Angles

You can input up to four keyed angles for the tool.

After the keyed angles are entered, the corresponding key angle marker will be displayed in the workspace.

Note: It's best to define at least on Key Angle, even if it is only 0.

 

A1 – A4

Die Clearance

You can record up to four die clearances.

D1 – D4

Dead Zone

Dead zones indicate the no-punch safety area reserved around each tool within the system. The values are half of the desired overall dead zone. Type the X and Y dimensions.

When the dead zone value is specified on the special tool properties window on the right, the system will show the dead zone in construction lines.

Overlap

You can record the overlaps and scallop height.

X Overlap/Scallop Height

For non-round tools, the X Overlap value allows you to specify the distance the tool should overlap in the X or horizontal direction. For round tools, Scallop Height allows you to define the height of the scallop formed during a nibble process. The smaller the value, the less the scallop.

Y Overlap

For non-round tools, the Y Overlap value allows you to specify the distance the tool should overlap in the Y or vertical direction.

 

 

 

Saving a Special Tool

Save a special tool as you would any other part file. Save or Save As may be selected from the File menu. Note: Changes saved to a Special Tool in the Special Tool Designer module will automatically be passed to the Tool Inventory.

Loading a Special Tool

You can easily examine or modify a special tool you previously saved. Select Open from the File menu. When the Open dialog box appears, type a file name in the File name: text box, or navigate through the list and select the name of the special tool. Click Open to load the special tool into the work area.

Importing Tool Designs

You can also import tool designs saved as DXF, IGES and DWG files. Click the Files of type: arrow and select DXF (*.dxf), IGES (*.igs) or DWG (*.dwg) from the drop-down list. The dialog box updates, listing the files having the selected filename extension in the \Spectool folder by default.

Type a file name in the File name: text box, or navigate through the list and select the name of the tool design file. Click Open to load the tool into the work area. The software automatically converts the selected DXF, IGES or DWG file to the Special Tool (*.spt) format when you load it.

Note: When you load a DXF, IGES or DWG tool, the bottom left corner of the geometry is placed at the center of the tool. You must relocate the tool to the correct origin.

Define Special Tool

The Define Special Tool option on the Tool menu allows you to select part patterns and define them as special tools. To define a special tool requires three overall steps: you must draw a marquee around the pattern(s), determine the center point, and then edit the information in the Define Special Tool window.

Notes: Use in Tool View.

The system uses the overall rectangular zone of the selected patterns to calculate the tool size and to determine the default center origin.

 If you specify a center point other than the default, the system multiplies the overall rectangular zone by twice the distance specified for the center origin.

When patterns are defined as a Special Tool, these patterns are automatically changed to a group.

Example: Define Special Tool

You have four center rectangles that you want to define as a special tool. Select Define Special Tool from the Special Tool submenu. Move into the work area. The system prompts you to select the patterns you want to define as a special tool. Move the crosshair to a point that is above and to the left of the four rectangles. Click the left mouse button to start the marquee. Move the crosshair down and right to enclose the patterns. When all the patterns are enclosed within the box, click the left mouse button.

Selecting the patterns for the special tool.

The system now prompts you for the center point. Press <Enter> to accept the default center point, or input the X and Y Offset coordinates and press <Enter>. Click the right-mouse button to complete the operation. The Define Special Tool window appears.

Selecting the center point for the special tool.

Define Special Tool Window

When you have selected the patterns and specified the X/Y Offset for the special tool, the Define Special Tool window appears. The preview pane to the right displays a thumbnail image of the selected patterns.

Option

Description

Station Size

Type the station size required for the tool.

Station Size Toggle Button

The toggle button next to the Station Size text box allows you to toggle through the available keyed or auto-index station sizes of the currently loaded turret. The software will analyze the overall size of the patterns and automatically select the next largest station size, but you can also type a new value in the Station Size text box to overwrite the calculated value.

Tool Size

The software automatically calculates the tool size according to the overall rectangular zone of the selected patterns from the center origin or X and Y offset. You cannot edit this value.

Dimension (X and Y)

You can record an X and Y dimension (X is the smaller dimension; Y is the larger) for the tool.

Symmetrical

If you enable Symmetrical, you can specify whether the tool reacts to angles like a square or rectangular tool.

Square

If you select Square, you could assign the tool to patterns having the same direction, but at different angles. For example, 0°, 90°, 180° and 270° would be the same direction to a square tool. As long as the special tool is in the turret at one of specified angles, it can also be assigned to any other special tool that was at 90° intervals.

Rectangle

If you select Rectangle, you could assign the tool to patterns having the same direction, but at different angles. For example: 0° and 180° would be the same direction, as would 90° or 270°.

Keyed Angle (A1-A4)

Use the text boxes, A1 to A4, to record up to four angles at which the tool can be keyed.

Die Clearance (D1-D4)

Use the text boxes, D1 to D4, to record up to four die clearances.

Dead Zone (X and Y)

Dead zones indicate the safety area reserved around each tool within the system will not punch. The values are half of the desired overall dead zone. Type the dimensions in the X and Y text boxes.

Save to Current Tool Inventory

If there is a check mark in the Save to Current Tool Inventory check box, the system adds the special tool to the currently loaded Tool Inventory.

Special Tool Folder

The system saves the special tool to the default \Spectool folder, but you can click the navigation button to the right of the path information to choose an alternate directory or new setup directory.

To save the special tool that you have defined, click in the File Name field and type a name for the special tool. The system will automatically add the *.spt filename extension.

Define Cluster Tool Array

The Define Cluster Tool Array… option on the Special Tool submenu allows you to determine the center points of cluster tools (more than two tools in a group) to generate perforated sheets or part areas. This option allows you to select a pattern set, define a special tool from that set, and then search the part or sheet for identical cluster patterns. The system then assigns the tool as a single hit and continues to search for matching patterns.

You can use two methods to define a cluster tool array. You can select a pattern array, define it as a special tool, and then have the system apply it to the patterns. The other method involves the system searching for array patterns and assigning an existing special tool.

Notes: As a rule, the system attempts to apply the special tool to the array according to the Horizontal or Vertical options in the Define Cluster Tool Array window. The software essentially ignores any irregular shapes, thereby reducing the amount of processing time.

When prompted to select the cluster array area, the patterns in the array must match those of the special tool.

The system displays the “No cluster patterns match selected area” message if it cannot find any matching patterns during the first search path.

 If there are common distances between the centers of the special shape, the system will group the pattern as a pattern line, otherwise, a single hit placement is assigned to the grouped special tool.

The system displays a message when it completes the processing of the cluster area.

Define Cluster Tool Array Window

The options in the Define Cluster Tool Array window allow you to select cluster array patterns to define as special tools, and then assign the selected patterns as tools, or assign a previously defined special tool to a pattern array.

Option
