Cycle Parameters - HEIDENHAIN TNC 640 User Manual

Touch Probe Cycles: Automatic Tool Measurement | 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: The measured tool radius is written to
column R 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: The measured tool radius is compared to the
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 Q 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: The measured tool radius is compared to the
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
preset. 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)
