Cycle parameters
Q321 Center in 1st axis? (absolute): Center of the
ridge in the reference axis of the working plane.
Input range -99999.9999 to 99999.9999
Q322 Center in 2nd axis? (absolute): Center of the
ridge in the secondary axis of the working plane.
Input range -99999.9999 to 99999.9999
Q311 Ridge width? (incremental): Width of the
ridge, regardless of its position in the working plane.
Input range 0 to 99999.9999
Q272 Measuring axis (1=1st / 2=2nd)?: Axis in the
working plane in which the measurement is to be
made:
1: Reference axis = measuring axis
2: Minor axis = measuring axis
Q261 Measuring height in probe axis? (absolute):
Coordinate of the ball tip center (= touch point) in
the touch probe axis in which the measurement is
to be made. Input range -99999.9999 to 99999.9999
Q320 Set-up clearance? (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
Q260 Clearance height? (absolute): coordinate in
the touch probe axis at which no collision between
tool and workpiece (fixtures) can occur. Input range
-99999.9999 to 99999.9999
Q305 Number in table?: Enter the number in the
datum/preset table in which the TNC is to save
the coordinates of the ridge center. If Q303=1: If
you enter Q305=0, the TNC automatically sets the
display so that the new datum is on the ridge center.
If Q303=0: If you enter Q305=0, the TNC writes to
line 0 of the datum table. Input range 0 to 99999
Q405 New datum? (absolute): Coordinate in the
measuring axis at which the TNC should set the
calculated ridge center. Default setting = 0. Input
range -99999.9999 to 99999.9999
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
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).
Q381 Probe in TS axis? (0/1): Specify whether the
TNC should also set the datum in the touch probe
axis:
0: Do not set the datum in the touch probe axis
1: Set the datum in the touch probe axis
