Cycle parameters
Measure tool=0 / Check tool=1: Select whether
the tool is to be measured for the first time or
whether a tool that has already been measured
is to be inspected. If the tool is being measured
for the first time, the TNC overwrites the tool
radius R and the tool length L in the central tool file
TOOL.T by the delta values DR = 0 and DL = 0. If
you wish to inspect a tool, the TNC compares the
measured data with the tool data stored in TOOL.T.
The TNC calculates the deviations and enters them
as positive or negative delta values DR and DL in
TOOL.T. The deviations are also available in the Q
parameters Q115 and Q116. If the delta values are
greater than the permissible tool tolerances for wear
or break detection, the TNC will lock the tool (status
L in TOOL.T).
Clearance height: Enter the position in the spindle
axis at which there is no danger of collision with
the workpiece or fixtures. The clearance height is
referenced to the active workpiece datum. If you
enter such a small clearance height that the tool
tip would lie below the level of the probe contact,
the TNC automatically positions the tool above
the level of the probe contact (safety zone from
safetyDistStylus). Input range -99999.9999 to
99999.9999
Cutter measurement? 0=No / 1=Yes: Choose
whether the control is also to measure the individual
teeth (maximum of 20 teeth) NC blocks
