Additional
commands
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, there is a possibility to use additional commands when
programming.
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!
