7 Programming: Canned Cycles, sub-programs

To use the Outside Corner Finding Cycle:



Place the probe in the spindle with its tool number active and the 
tool type set to "Touch Probe".



Manually jog the probe stylus less than 0.1" (2.54 mm) away from 
the outside of the corner you wish to find in X & Y. If H = 1, the Z-axis 
should be within 0.1" (2.54 mm) above the part otherwise the Z-axis 
should be at the side picking depth.



Type G142 Qn Wn. If this is run from inside a program, this line 
needs to be repeated for every corner you wish to find or whose 
position you want to reestablish. 



Execute the line in Manual Data Input Mode by touching NC Start.

DistInX

A

The distance from the starting point to 
move in the X-axis to find the top of the part. 
The default is toward the corner being 
found 0.4" (10.16 mm). (Optional)

DistInY

B

The distance from the starting point to 
move in the Y-axis to find the top of the part. 
The default is toward the corner being 
found 0.4" (10.16 mm). (Optional)

X

I

This causes the cycle to make a protected X 
move to the coordinate entered relative to 
the current active work coordinate before 
finding the corner. 
(Optional)

Y

J

Same as I only for the Y-axis. (Optional)

Z

K

Same as I only for the Z-axis. (Optional)

Offset

W

Work Coordinate to update with edge 
location in X- and Y-axes. If set, work 
coordinate is updated. Work coordinate 
register is not updated if not set and a 
warning message tells the operator no 
update has taken place if W is not set. 
(Optional)

When positioning the probe from within the program, you 
should always use the G146 (Protected Probe Positioning) 
cycle (see G146 instructions later in this document) or use 
the I, J, or K cycle parameters for the same purpose.
