G18 (ZX)
Retraction, milling
- only for "Cuboid" blank
Retraction planes above the workpiece.
During machining, the tool travels in rapid traverse from the tool change point to the
return plane (RP) and then to the safety clearance (SC). The machining feedrate is
activated at this height. When the machining operation is finished, the tool traverses
at the machining feedrate away from the workpiece to the safety clearance height. It
traverses from the safety clearance to the retraction plane and then to the tool change
point in rapid traverse. The retraction plane is entered as an absolute value.
The safety clearance must be entered as an incremental value (without sign).
Note:
"Retraction milling" cannot be used in turning applications.
Retraction turning
- only for "Cylinder",
"Tube", "Centered cu‐
boid", "Polygon" and
"Without" blanks
The retraction area indicates the area outside of which collision-free traversing of the
axes must be possible.
