Can you guys tell me what macro number is used for the x and y and z machine position on either of these controls? I am looking to program a probe and think this should exist but I have been able to find them using the macro book i have.

[zavateandu]

give me an email at :[email protected]
i will give you all the macro you need.

[sinha_nsit]

See the attachment. This is for i-series control.

Thanks guys hope to figure this out.

Zavateandu, email sent, thanks for any help you can provide.

Sinha, can you elaborate on that last column? Read operation during tool movement. What does that specifically mean? Will it not read while moving but maybe read while it is stopped?

[sinha_nsit]

Yes. That is correct. The current tool position is not really the instantaneous tool position. It can be read only after the tool stops.

[stang623]

It will read it in a program though correct? As long as machine is stopped?

Should I be using skip signal position? How do I back out machine position from skip signal position?

[sinha_nsit]

Yes.

In probing, skip signal position is used. You touch a surface (using G31) and store the skip signal position in a variable. Then you touch another surface and again store the skip signal position in another variable. The difference in the two variables is the distance between the two surfaces. The diameter of the probe ball would have to be taken into account wherever needed.

[stang623]

OK i see, but skip signal looks like world cordinates, how do i get from there to machine cordinates...because I'm trying to find values for my G54, G55, etc?

[sinha_nsit]

You need the coordinate of the current tool position in MCS, not the coordinate of skip-signal position.
If you want to use the skip-signal position for G54 etc, bring the tool to this position first.
The formula is:
X-offset of G54 = (X-coordinate of the current tool position, in MCS) - (X-external offset)
etc.

Alright, so I have been making progress on this however I'm stuck again and need some help. I found the following code on one of the machines of ours and I'm wondering how the heck it works...it is the simple part of turning the probe on.

For some reason it never spins the spindle on. Can anyone explain the basic functionality that this is supposed to accomplish to me?

[sinha_nsit]

For measuring the dimensions of a part through a touch probe, the spindle is not rotated..

[stang623]

This sub program is called to turn probe on. It is supposed to turn spindle on at 500 Rpms for a second which turns the probe on. Then stop and ur ready to probe. It never gets to the 500 rpm part of the program.
