Cycle Parameters - HEIDENHAIN TNC 620 User Manual

Measure the tool length and radius (Cycle 33 or 483, DIN/
ISO: G483, software option 17 Touch Probe Functions software

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 are checking a tool, the measured tool
data is compared with the data in the tool table.
The TNC calculates the deviations and enters them
as positive or negative delta values DR and DL
in TOOL.T. The deviations can also be used for
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).
Parameter number for result ?: Parameter
number in which the TNC saves the status of the
measurement result:
0.0: Tool is within tolerance
1.0: Tool is worn (LTOL and/or RTOL exceeded)
2,0: Tool is broken (LBREAK and/or RBREAK
exceeded). If you do not wish to use the result
of measurement within the program, answer the
dialog prompt with NO ENT.
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)
