Programming example for circumferential milling
A workpiece contour needs to be milled at the circumference. It is a question of programming
from the top edge of the workpiece and the engaged length ISD is taken into account. In the
example, compensation is performed to the right based on an ISD of 20.
Example involving
CUT3DC
ORID No changes in orientation in inserted circular blocks at external
corners. Orientation motion is performed in the linear blocks.
ORIC Travel path is extended by means of circles. The change in orien-
tation is also performed proportionately in the circle.
Face milling
CUT3DFS Constant orientation (3-axis). Tool points in the Z direction of the
coordinate system defined via G17 - G19. Frames do not have
any effect.
CUT3DFF Constant orientation (3-axis). Tool in Z direction of the coordinate
system currently defined via the frame.
CUT3DF 5-axis with variable tool orientation
3D circumferential milling with limitation surface (combined circumferential/face mill-
ing)
CUT3DCC CNC program relates to the contour on the machining surface.
CUT3DCCD The CNC program relates to the tool center point path.
