Additional com‐
mands
The contour is finished in continuous-path mode (G64). As a result, contour transitions
such as corners, chamfers or radii may not be machined precisely.
If you wish to avoid this, then it is possible to use additional commands when program‐
ming.
Example:
For a contour, first program the X parallel straight line and then enter "G9" (non-modal
exact stop) for the additional command parameter. Then program the Y-parallel straight
line. The corner will be machined exactly, as the feedrate at the end of the X-parallel
straight line is briefly zero.
Note:
The additional commands are only effective for path milling!

Creating contour elements
After you have created a new contour and specified the starting point, you can define the
individual elements that make up the contour.
