HEIDENHAIN TNC 426 B, TNC 430
ú
Milling depth Q1 (incremental value): Distance
between workpiece surface and contour floor
ú
Finishing allowance for side Q3 (incremental value):
Finishing allowance in the working plane
ú
Workpiece surface coordinate Q5 (absolute value):
Absolute coordinate of the workpiece surface
referenced to the workpiece datum
ú
Clearance height Q7 (absolute value): Absolute height
at which the tool cannot collide with the workpiece.
Position for tool retraction at the end of the cycle.
ú
Plunging depth Q10 (incremental value):
Dimension by which the tool plunges in each infeed
ú
Feed rate for plunging Q11: Traversing speed of the
tool in the tool axis
ú
Feed rate for milling Q12: Traversing speed of the tool
in the working plane
ú
Climb or up-cut ? Up-cut = -1 Q15:
Climb milling:
Input value = +1
Conventional up-cut milling
Input value = –1
To enable climb milling and up-cut milling alternately
in several infeeds
Input value = 0
