209 HEIDENHAIN TNC 410, TNC 426, TNC 430
ú Milling depth Q1 (incremental value): Distance
between the cylindrical surface and the floor of the
contour
ú Finishing allowance for Q3 (incremental value):
Finishing allowance in the plane of the unrolled
cylindrical surface. This allowance is effective in the
direction of the radius compensation.
ú Set-up clearance Q6 (incremental value):
Distance between the tool tip and the cylinder surface
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 Radius Q16: Radius of the cylinder on which the
contour is to be machined
ú Dimension type ? Q17: The dimensions for the rotary
axis of the subprogram are given either in degrees (0)
or in mm/inches (1)
