Touch Probe Cycles: Automatic Measurement of Workpiece Misalignment | BASIC ROTATION compensation
via rotary axis (Cycle 403, DIN/ISO: G403)
Q312 Axis for compensating movement?: Define
with which rotary axis the TNC is to compensate
the measured misalignment:
0: Automatic mode—the TNC uses the active
kinematics to determine the rotary axis to be
aligned. In Automatic mode the first rotary axis of
the table (as viewed from the workpiece) is used
as compensation axis. Recommended setting.
4: Compensate misalignment with rotary axis A
5: Compensate misalignment with rotary axis B
6: Compensate misalignment with rotary axis C
Q337 Set to zero after alignment?: Define
whether the TNC should set the angle of the
aligned rotary axis to 0 in the preset table or in the
datum table after the alignment.
0: Do not set the angle of the rotary axis to 0 in
the table after alignment
1: Set the angle of the rotary axis to 0 in the table
after alignment
Q305 Number in table? Enter the number in the
preset table in which the TNC is to enter the basic
rotation. Input range 0 to 99999
Q305 = 0: The rotary axis is set to zero in number
0 of the preset table. An entry is made in the
OFFSET column. Additionally, all other values (X, Y,
Z, etc.) of the currently active preset are saved in
row 0 of the preset table. The preset from row 0 is
also activated.
Q305 > 0: Specify the row of the preset table in
which the TNC should set the rotary axis to zero.
An entry is made in the OFFSET column of the
preset table.
Q305 depends on the following parameters:
Q337 = 0 Parameter Q305 is not effective
Q337 = 1 Parameter Q305 is effective as
described above
Q312 = 0: Parameter Q305 is effective as
described above
Q312 > 0: The entry in Q305 is ignored. An entry
is made in the OFFSET column in the row of the
preset table active when the cycle is called
Q303 Meas. value transfer (0,1)?: Specify if the
determined basic rotation is to be saved in the
datum table or in the preset table:
0: Write the measured basic rotation as datum
shift in the active datum table. The reference
system is the active workpiece coordinate system
1: Write the measured basic rotation into the
preset table. The reference system is the machine
coordinate system (REF system).
Q380 Ref. angle in ref. axis?: Angle with which
the TNC is to align the probed straight line. Only
effective if the rotary axis = Automatic mode or C
is selected (Q312 = 0 or 6). Input range -360.000
to 360.000
