7 Programming: Canned Cycles, sub-programs

To use the Inside/Outside Boss/Hole 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 the approximate center in X & Y within 
0.1" (2.54 mm). 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 G144 Qn Xn Yn Wn. If this is run from inside a program, this 
line needs to be repeated for every boss/hole you wish to find or 
whose position you want to reestablish.



Execute the line in Manual Data Input Mode by touching Start

DistInY

B

The distance from the starting point to 
move in the Y-axis to find the top of the part. 
The default is the current probe position. 
(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 Boss/Hole center. 
(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 the center 
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)

Repeat
Meas

R

If set to 1, the cycle does a preliminary 
measure in the X-axis to get on center 
before measuring the Y-axis, making a total 
of 6 touches. If set to 0, the cycle only 
measures "X" once for a total of 4 touches. 
Default is: 0.
(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.
