Cycle parameters
U 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).
U
Parameter number for result?: Parameter number in
which the TNC stores the status of the
measurement:
0.0: Tool is within the tolerance
1.0: Tool is worn (LTOL or/and RTOL exceeded)
2.0: Tool is broken (LBREAK or/and RBREAK exceeded).
If you do not wish to use the result of measurement
within the program, answer the dialog prompt with
NO ENT.
U 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 MP6540).
Input range -99999.9999 to 99999.9999, alternatively
PREDEF
U Cutter measurement? 0=No / 1=Yes: Choose whether
the control is also to measure the individual teeth
(maximum of 99 teeth)
