Measuring Cycles for Turning Machines
6.3 CYCLE982 tool: Measure turning and milling tools
Measuring variant
Example 6:
Radial position,
R ≠ 0,
Measuring without
reversal,
4 measurements
necessary
_MVAR=14002
Direction of
measurement for
determining length L1
opposite to traversing
direction, measuring
procedure as for
_MVAR=x13002 but with
different traversing
motion
Notes:
Length measurements
for L1 (P3, P4) are
performed here at the
same measuring point –
without rotating the
spindle by 180 degrees.
The same cutting edge is
always measured
(starting angle _STA1).
The width of the milling
tool must be considered
when selecting the
starting position or
dimension a!
