Acu-Rite CNC 3500i user manual 205

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.
