Assigning Lathe Tool Inserts

Introduction

BobCAD-CAM allows you to assign geometry to define custom lathe tool inserts for tools that can't be created using the provided insert types.

To Assign a Tool Insert

1. In the graphics area, draw the 2D shape of the insert.
   
   
2. At the position of the attachment point to the tool holder, place a dashed circle.
   
   It does not matter which dashed pattern is chosen, just that the circle itself is not solid.
   
   
3. Place a point at the theoretical tool point.
   
   This point is normally tangent to the forward and bottom extents of the tool nose radius.
   
   

 

 

 

 

2. To open the Tool Library, do one of the following:
   
   
• Right-click CAM Defaults, and click Tool Library:
  
  
• Right-click Turning Tools, and click Tools,
  
  
3. In the Tool Library, select the lathe tool category that you want to modify.
   
   
4. In the list, click the tool that you want to modify, and click expand the Tool Parameters section on the right.
   
   (If you are creating a new tool, just select the category, and click Add.)
   
5. In the Create/Modify dialog box, select the radio button for Custom Shape.
   
6. Click Assign Tool Insert.
   
   
7. In the graphics area, to select the insert geometry, click and drag a window around the entire drawing.
   
   The Insert Shape, Match Circle, and Reference Point are all automatically assigned to the proper lists.
   
   
8. Click OK.
   
   The holder geometry is now assigned to the selected tool.
   
   Click OK to save the changes and return to the Tool Library.
   
   

 

Note: The Tool Attachment Circle is only required if the insert is to be associated with a tool holder.
