Cycle Parameters - HEIDENHAIN TNC 620 User Manual

MEASURE KINEMATICS (Cycle 451, DIN/ISO: G451, option)

Cycle parameters

Mode (0=Check/1=Measure) Q406: Specify
whether the TNC should check or optimize the
active kinematics:
0: Check active kinematics. The TNC measures
the kinematics in the rotary axes you have defined,
but it does not make any changes to it. The
TNC displays the results of measurement in a
measurement log.
1: Optimize active kinematics. The TNC measures
the kinematics in the rotary axes you have defined
and optimizes the position
the active kinematics.
Exact calibration sphere radius Q407: Enter the
exact radius of the calibration sphere used. Input
range 0.0001 to 99.9999
Set-up clearance Q320 (incremental): Additional
distance between measuring point and ball tip.
Q320 is added to SET_UP in the touch probe table.
Input range 0 to 99999.9999; alternatively PREDEF
Retraction height Q408 (absolute): Input range
0.0001 to 99999.9999
Input 0:
Do not move to any retraction height. The TNC
moves to the next measuring position in the axis
to be measured. Not allowed for Hirth axes! The
TNC moves to the first measuring position in the
sequence A, then B, then C.
Input >0:
Retraction height in the untilted workpiece
coordinate system to which the TNC positions
before a rotary axis positioning in the spindle
axis. Also, the TNC moves the touch probe in the
working plane to the datum. Probe monitoring is
not active in this mode. Define the positioning
velocity in parameter Q253.
Feed rate for pre-positioning Q253: Traversing
speed of the tool in mm/min during positioning.
Input range 0.0001 to 99999.9999; alternatively
