Programming example, TRACYL

Machining grooves with groove wall compensation
MD24100_TRAFO_TYPE_1 = 513
Contour
It is possible to machine a groove which is wider than the tool by using address OFFN=... to program the compensation
direction (G41, G42) in relation to the programmed reference contour and the distance of the groove side wall from the
reference contour.
Tool radius
The tool radius in relation to the groove side wall is automatically taken into account with G41, G42. The full functionality of
the plane tool radius compensation is available (steady transition at outer and inner corners as well as solution of bottleneck
problems).
Groove with groove wall offset - figure as example:
TRACYL is used for the milling of grooves on a peripheral cylinder surface. During this process, the "Path I" and "Path II"
sections are processed using different OFFN values.
CC is the channel axis name of the rotary axis, milling radius of T1, D1: 8.000 mm
