Introduction
When programming free contours, for surface grinding it usually involves dressing contours.
In this case, under certain circumstances the dressing contours are machined using multiple
tools (dressing tools). The X position must be programmed in the DIN program at X0, as the
axis is not included in the contour path.
The approach also takes place outside the contour, as the approach movement should be
completely realized using G0!
The commands for continuous-path mode (G64) and tool nose radius compensation
(G41/G42) must be inserted manually.
Note
When programming the free contour, the display of the coordinate system is determined by
display machine data MD290 CTM_POS_COORDINATE_SYSTEM.
