for parts we do with .02mm true position if its not at a0c0 I use a sub without the twp and pick it up with the probe.

the ruby will build up with aluminum after a while. we ordered an m4-m5 adapter so we can use the silicon nitrate probes from the cmm(Renishaw silicon nitrate really expensive )

Talk to Qmark they make the Silicon Nitrate tips much cheaper and just as good.

Hey Cincy K, did you ever figure it out? We also have the MX520 but got the EZ-5 Retrofit kit from Matsuura. What we do is set the gauge ball at the 1:30 position on the table (back right corner) as far away from center (for best precision) without over traveling. We have the Marposs probe and not the Renishaw so Matsuura had to make/modify macros for us so the Marposs probe talked to the EZ-5 part of the control correctly. The program checks the ball 3 times (120° apart) on the C axis while A0.0, Then it tilts at A-45 (I think) and does it again at 3 positions around C axis.

FYI, it's NOT really a do it all set and forget kind of alignment. I'd treat it more as a nice reference start point, but not something that will get you aligned to a really tight specs ))

If anyone cares, I created a similar program to find the -Y- and -Z- centerline based on 3 points. 

Basically, store the following variables then run the below code. It will set your 19700's. 

#750= 1st Y position

#751= 1st Z position

#752= 2nd Y position

#753= 2nd Z position

#754= 3rd Y position

#755= 3rd Z position

So what three points are you taking? 

Ive tried to get Methods to help us setup these parameters on a robodrill with basically no help at all.

I am using this to work on a robodrill right now. Our table is mounted to the left side of the machine, so B tilts positive around the Y axis.

Just playing with the math in this macro, I believe the first point would be taken at B0, the second at B45, the third at B90

So....you can get X and Y zero by just probing the bore or indicating while the table is at B zero.

You will likely get a different X value using this macro with a probe.

The difference between the value you get with the macro and the value you get while at B zero would be what you put in 19703

I start with the ball at 12 o'clock position and the table at -A- zero, -B- zero and take the first Y and Z. 

Then I tilt to A45 deg and take the second set of numbers. 

Then I tilt to A90 and take the third set. 

The actual -A- angle doesn't matter. Of course the further apart the angles, the more accurate your solution will turn out.  But it is important NOT to move you -B- axis. That must stay at the same -B- as you started or else the math will not work.

 

Let me know if you need a better explanation.

BTW, if you have Vericut, you can preload the variables for #750 thru #755 and run the code. That's what I did. I drew a circle in MasterCam going through 3 points, and used the point locations for my variable. Then ran it and the solution should come out the Z and Y of the center of the circle that intersects the 3 points.

Here is the complete code for our Makino NX51. Keep in mind that this particular one is for a horizontal, but the math is the same no matter if you want to find the centerline of -A-, -B-, or -C-

The #900 is the size of the ball being probed.

You can also do the poor mans version with the macro calc found here : http://www.ncplot.com/freetools.htm
