1st side length
Q218 (incremental): Length of the
surface to be machined in the reference axis of the
working plane. Use the algebraic sign to specify the
direction of the first milling path in reference to the
starting point in the 1st axis
. Input range
-99999.9999 to 99999.9999
2nd side length
Q219 (incremental): Length of the
surface to be machined in the minor axis of the
working plane. Use the algebraic sign to specify the
direction of the first stepover in reference to the
starting point in the 2nd axis
. Input range
-99999.9999 to 99999.9999
Maximum plunging depth
Q202 (incremental):
Maximum amount that the tool is advanced each
time. The TNC calculates the actual plunging depth
from the difference between the end point and
starting point of the tool axis (taking the finishing
allowance into account), so that uniform plunging
depths are used each time. Input range 0 to
99999.9999
Allowance for floor
Q369 (incremental): Distance
used for the last infeed. Input range 0 to 99999.9999
Max. path overlap factor
Q370: Maximum stepover
factor k. The TNC calculates the actual stepover from
the second side length (Q219) and the tool radius so
that a constant stepover is used for machining. If you
have entered a radius R2 in the tool table (e.g. tooth
radius when using a face-milling cutter), the TNC
reduces the stepover accordingly. Input range 0.1 to
1.9999; alternatively PREDEF
