3.3 Automatic Workpiece Measurement

8 1st measuring point in 1st axis Q263 (absolute):

coordinate of the first touch point in the reference

axis of the working plane.

8 1st measuring point in 2nd axis Q264 (absolute):

coordinate of the first touch point in the minor axis of

the working plane.

8 1st measuring point in 3rd axis Q294 (absolute):

coordinate of the first touch point in the touch probe

axis.

8 2nd measuring point in 1st axis Q265 (absolute):

coordinate of the second touch point in the reference

axis of the working plane

8 2nd measuring point in 2nd axis Q266 (absolute):

coordinate of the second touch point in the minor axis

of the working plane

8 2nd measuring point in 3rd axis Q295 (absolute):

coordinate of the second touch point in the touch

probe axis.

8 3rd measuring point in 1st axis Q296 (absolute):

coordinate of the third touch point in the reference

axis of the working plane.

8 3rd measuring point in 2nd axis Q297 (absolute):

coordinate of the third touch point in the minor axis of

the working plane.

8 3rd measuring point in 3rd axis Q298 (absolute):

coordinate of the third touch point in the touch probe

axis.

8 Setup clearance Q320 (incremental): Additional

distance between measuring point and ball tip. Q320

is added to column SET_UP.

8 Clearance height Q260 (absolute): Coordinate in the

touch probe axis at which no collision between tool

and workpiece (fixtures) can occur.

8 Measuring log Q281: Definition of whether the TNC is

to create a measuring log:

0: No measuring log

1: Generate measuring log: the TNC saves the log file

TCHPR431.TXT by default in the directory TNC:\

2: Interrupt the program run and display the

measuring log on the screen. Resume program run

with NC Start.

Example: NC blocks
