Cycle Parameters - HEIDENHAIN TNC 620 User Manual

Touch Probe Cycles: Automatic Kinematics Measurement | PRESET COMPENSATION (Cycle 452, DIN/
ISO: G452, option)

Cycle parameters

Q407 Radius of calib. sphere? Enter the exact
radius of the calibration sphere used. Input range
0.0001 to 99.9999
Q320 Set-up clearance? (incremental): Define
an 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
Q408 Retraction height? (absolute) Input range
0.0001 to 99999.9999
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
>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. The touch probe
monitor is not active in this mode. Define the
positioning speed in parameter Q253
Q253 Feed rate for pre-positioning? Enter the
traversing speed of the tool in mm/min during
positioning. Input range 0.0001 to 99999.9999;
alternatively FMAX, FAUTO, PREDEF
Q380 Ref. angle in ref. axis? (absolute): Enter
the reference angle (basic rotation) for measuring
the measuring points in the active workpiece
coordinate system. Defining a reference angle can
considerably enlarge the measuring range of an
axis. Input range 0 to 360.0000
Q411 Starting angle in A axis? (absolute): Starting
angle in the A axis at which the first measurement
is to be made. Input range -359.999 to 359.999
Q412 End angle in A axis? (absolute): End angle in
the A axis at which the last measurement is to be
made. Input range -359.999 to 359.999
Q413 Angle of incidence in A axis?: Angle of
incidence in the A axis at which the other rotary
axes are to be measured. Input range -359.999 to
359.999
Q414 No. of meas. points in A (0...12)?: Number
of probe measurements with which the TNC is to
measure the A axis. If the input value = 0, the TNC
does not measure the respective axis. Input range
0 to 12
