Touch Probe Cycles: Automatic Tool Measurement
17.5
Measuring tool radius (Cycle 32 or 482, DIN/ISO: G482)
Cycle parameters
Tool measurement mode (0-2)?: Specify whether
and how the determined data will be entered in the
tool table
0:
of the tool table TOOL.T, and the tool compensation
is set to DR=0. If there is already a value stored in
TOOL.T, it will be overwritten.
1:
tool radius R from TOOL.T. It then calculates the
deviation from the stored value and enters it into
TOOL.T as the delta value DR. The deviation can
also be used for parameter Q116. If the delta value
is greater than the permissible tool radius tolerance
for wear or break detection, the TNC will lock the
tool (status L in TOOL.T)
2:
tool radius R from TOOL.T. The TNC calculates the
deviation from the stored value and enters it in
Q parameter Q116. Nothing is entered under R or
DR in the tool table.
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 (RTOL exceeded)
2.0: Tool is broken (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
Probe the teeth? 0=no/1=yes: Choose whether the
control is to measure the individual teeth (maximum
of 20 teeth)
