Macro Help

[X-L Engineering Corp]

I hope I can explain this well enough.

I'm running a probing routine to align a milled slot in the "Y" axis. First I'm going to do a 3 Point Bore for the Datum and then a Web Measure in the slot I need to have it to calculate a G68 Rotate of the program I was going to do an ATAN but I'm not sure if that is what I should be using to produce the correct G68 Rotate.

 

Any help would be appreciated I get buy with Probe Programming but I’m not that strong in it.

This is my Routine that I have now.

not fluent with macro language without me notes and banging head on table a couple of times but, might you want to probe slot and rotate coordinate system then probe bore for zero?

[X-L Engineering Corp]

Thats fine but not sure if I have it programed right to get the correct rotation?

[Tim Johnson]

I do'nt have time to go through your calcs right now but right off I don't see the "Y" locations being used. I would think you should either 3 point bore measure both ends of the slot -or- web measure both ends (as near as possible) and used the fixed "Y" distance to find the correct angle.

[X-L Engineering Corp]

After each rotine I force the #135 out to #106 from the Web and #107 from the 3 Point Bore.

I have a set "Y.13" distance and I'm looking for the Angle as the "X" changes for my G68.

[Lars Christensen]

Have you tried contacting Renishaw? they have always been very very helpful with stuff like this

Give this a try. It's not tested so keep an eye out.

[Dave Ball]

Ted I was wondering why your not using the P9843 angle measurement cycle and then just use G68 to rotate? All the math for finding the angle is in the P9843 already.

[X-L Engineering Corp]

Thanks Tim I'll try it tomorrow

I didn't know about that one I will look into it thanks.

I just looked into P9843 I need to be able to Measure at 2 different "Z" heights along "Y" but thanks for letting me know about that one I'm sure I'll be using it.
