To use the automatic tool preset:
Install all the tools you wish to set, in the tool changer.
Type in: G151 T(tool#) D(tool rough diameter) Q2 If run from the 
inside of a program, this line needs to be repeated for every tool that 
you want to set.
Execute that line if you are in Manual, or run the program if you have 
set all the tools up in a program.
If you have done a single tool in Manual, that tool is now measured 
and you are ready to measure the next tool. If you have placed 
multiple lines in a program, one for each tool, all your tools are 
measured and ready for use.
Shell mill style tools that have a hole in the center of the bottom do 
not work with this canned cycle; in this case, you must use the 
manual canned cycles G152 Manual Tool Length Measure for 
Special Tools for length and G153 Manual Tool Diameter Measure 
for Special Tools for diameter. See Table 5-45, G151 Address 
Words. This cycle is only good for drills, taps, reamers, ball nosed 
endmills, and standard endmills with a flat bottom, the cycle 
updates length and diameter tool registers clearing anything in the 
wear registers.
The following examples are described for machining centers with 
automatic tool changers.
Format: G151 T(tool#)
With T cycle parameter only set:
The machine rapids the Z-axis up, picks up the tool designated in the 
T parameter, and rapids directly over the center of the probe stylus.
The Z-axis rapids down the distance placed in the 
ZRapidToStartPositionFromHome machine setup parameter then 
starts feeding down toward the probe for the initial touch at the 
feedrate that was placed in the ZFirstPickFeedRate_Fast machine 
setup parameter, then backs up and retouches the probe at the 
feedrate that is in the ZFirstPickFeedRate_Slow.  
The tool-length register for that tool is now updated, and that tool's 
length-wear register is set to zero.
Then the Z-axis rapids up to home position.
If you have done a single tool in Manual, that tool is now measured 
and you are ready to measure the next tool. If you have placed 
multiple lines in a program, one for each tool, the machine then 
grabs the next tool and repeats steps 1 through 4 until all the tools 
have been measured.
