Cycle parameters
 Center in 1st axis Q321 (absolute): Center of the
ridge in the reference axis of the working plane. Input
range -99999.9999 to 99999.9999
 Center in 2nd axis Q322 (absolute): Center of the
ridge in the minor axis of the working plane. Input
range -99999.9999 to 99999.9999
 Width of ridge Q311 (incremental): Width of the
ridge, regardless of its position in the working plane.
Input range 0 to 99999.9999
 Measuring axis (1=1st axis / 2=2nd axis) Q272:
Axis in which the measurement is to be made:
1: Reference axis = measuring axis
2: Minor axis = measuring axis
 Measuring height in the touch probe axis Q261
(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
 Set-up clearance Q320 (incremental): Additional
distance between measuring point and ball tip. Q320
is added to MP6140. Input range 0 to 99999.9999;
alternatively PREDEF
 Clearance height Q260 (absolute): Coordinate in the
touch probe axis at which no collision between touch
probe and workpiece (fixtures) can occur. Input range
-99999.9999 to 99999.9999; alternatively PREDEF
 Number in table Q305: Enter the number in the
datum/preset table in which the TNC is to save the
coordinates of the ridge center. If you enter Q305=0
and Q303=1, the TNC automatically sets the display
so that the new datum is on the ridge center. If you
enter Q305=0 and Q303=0, the TNC writes the ridge
center in line 0 of the datum table. Input range 0 to
99999
 New datum Q405 (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
