HEIDENHAIN CNC PILOT 640 431
5.12 Face contours in smart.Turn
Linear slot on face
You can find the reference dimension ZR with the "select reference
plane" function (siehe Seite 425).
ICP generates:
 The FACE_C section code with the reference dimension parameter.
In nested contours, ICP generates only one section code.
 A G308 with the parameters contour name and milling depth.
 A G301 with the parameters of the figure.
 A G309.
Circular slot on face
You can find the reference dimension ZR with the "select reference
plane" function (siehe Seite 425).
ICP generates:
 The FACE_C section code with the reference dimension parameter.
In nested contours, ICP generates only one section code.
 A G308 with the parameters contour name and milling depth.
 A G302 or G303 with the parameters of the figure.
 A G309.
