OMP40 Calibration

[tukes23]

I have a mazak VCN 510C-II with the OMP40, wired toolsetter, and inspection plus software. When my machine was installed the dealer we bought it from gave me some on-site training, but neglected to tell me any thing about the probes other than how to probe faces to set the WPC data in mazatrol. I broke a stylus about a week ago and i need to calibrate the probe for the new stylus but i don't know how. I can't make heads or tails of the examples in the inspection plus book and i don't know how to calibrate it in mazatrol. I have a calibrated ring gauge and all of the tools to do it i just don't know how and i don't want to try something and destroy the entire probe. i would just like to know how to go about using the inspection plus calibration macros, calibration in mazatrol, and any other information you might think is important to know. Any help would be greatly appreciated.

Generally, when you buy EIA probing and the Inspection Plus software, full training is included by Renishaw or Renishaw vendor. Did you not get that? If all you were trained on is to measure Z in Mazatrol... I'd be on the phone making some serious phone calls. Even if you only had Mazatrol probing, the training by Mazak should be more extensive than that. Check your sales order, it should show 1-3 days training (depending on how extensive the system is) by Renishaw plus install time. Get on the horn.... in the meantime....

This can get quite extensive. Do you have a copy of the Mazatrol Programming Manual? Look up probing and it goes over the steps for calibrating pretty well. For EIA, it's not too much different. You still have to sweep the ring gage, set your Z and update the Inspection Plus calibration program with these values before running the cycle. I'm always changing the calibration program number from standard but usually its a 8000 number. If your installer used the Macro generator from the install CD, then you should have the calibration program all formatted and you simply need to input the variables at the top of the program (it should contain notes so you know what you need to input).

Let's start from there and see where you get stumped. Do the reading while you're at the machine and it may be easier to follow with the programs and control in front of you.

well, i this morning i found my mazatrol manual and used the calibration cycles in the manual and it seems to have worked perfectly. i still have yet to figure out the inspection plus macros but hopefully this will be ok.

i was wondering, if i always use a mazatrol program to set my work offsets, do i need to calibrate the probe in EIA? will noty having used the vector calibration macro have an effect on my accuracy to set my theta angle?

No. Mazatrol retains the probe dynamics in the machine parameters. Renishaw maintains them in macro variables. Therefore they can be completely seperate and still function. Just don't calibrate one way and try to use another way....

will noty having used the vector calibration macro have an effect on my accuracy to set my theta angle?

Yes and no. This is the reason why you need to indicate the stylus in as close as possible. You will pick up Theta error depending on how much runout your probe stylus has. You can have the same problem with EIA probing depending on how your calibration macros work. Best practice is to indicate and keep the stylus as close as possible.
