Preparing DXF contour


The DXF path has to be prepared in a way that:

  1. The wire is clear from PCD and tool body at the end points of the contour
  2. The X-coordinate of contour start point and end point is not identical, because the software has to determine the ā€œmain profile directionā€ (blue arrow) from the difference of X-start-point and X-end-point

Determining the ā€œmachining modeā€


Due to the detected ā€œmain profile directionā€ (blue arrow), with the above contour example, the situation fits to the upper right sketch in the profile window. This means ā€œOuter machiningā€ has to be selected in this situation.



With this selection the relief angles on the outer contour section will be applied according to the general settings. But for the inner contour section the radial relief angle has to be applied in opposite direction. To enable this, the checkbox ā€œAngle valid for entire profileā€ has to be unchecked.

Edit individual angles


With the setting above the button ā€œEdit individual anglesā€ can be used to open the geometry window for setting individual relief angles for each contour element. In this window each contour element of the inner contour section (beginning with the vertical line on the front end) has to be identified and a suitable negative ā€œRadial relief angleā€ has to be assigned.

Setting the ā€œBackw. Path Bā€

For a ā€œcollision freeā€ escape from the inner contour end point the ā€œBackw. pathā€ has to be extended. With this setting the machine will move 8mm in X-direction before moving in Y-direction (Purple lines in simulation) .

The simulation also shows the correct change to the negative radial relief for the inner contour section
