Renishaw Probe - Variaxis 730 - Dynamic offset. Help!!

[Tinhman]

Good morning guys,

Please help me with this.

Machine is Variaxis 730 with Renishaw Probe.

I would like to probe the A rotation and update my dynamic work offset (G54.2 P1).

Could some body please guide me thru. this.??

Thanks in advance.

Not sure how old is your Mazak, but I remember some years ago their probing cycles were not able to do it..

Do you have the Renishaw Inspection Plus macros? I haven't tried to do what you're asking, but it shouldn't be too difficult. Do you have some more detail on exactly what it is you're doing? Maybe a sketch of the part and it's orientation?

 

You could probably use the 9818 macro to find the angle. If the macro won't write the angle to the Dynamic offset register, just write it to G54.1P300, and then copy it to G54.2P1 from G54.1P300 like this:

Thanks for all the reply guys.

 

Watcher:

I have a 2010 model.

 

Joe788:

Yes, i have Renishaw Inspection Plus macros. My part is about 20" dia, 8" tall and it has one flat face lay on front view. ( sorry, I can not post any picture in the moment)

Yes, it is exactly what i am thinking.

Here is what i tried to do:

It is working OK with XYZ but A and C

I will try it again when i have a chance.

 

Thanks

Dynamic offsets (G54.2) and a tilting axis is not going to happen.

It does work great for X,Y & Z & the rotational axis...tilting things really mess things up. See above link

Thanks for the info.

you mentioned something about "G54.4", i wonder if any body is using it. I mean, there is must be a solution for it.

The Renishaw Inspection Plus macros do allow you to probe with G54.2 active dependent on a setting in the 9724 program.

However G54.2 will only allow dynamic compensation in XY & Z in 5 axis machining.

G54.4 WILL allow compensation in A & C, BUT you cannot probe with G54.4 active.

I have done quite a lot of work on a Mazak Variaxis with Renishaw Probing to measure and update G54.4 values with success. Also managed to probe (with some heavy maths) at dynamically compensated angles.

Thansk for the info. guypb but i have a question.

How do i know my machine has G54.4 option turn on?

Is there any way i can check it?

Hi Tinhman, the page would be available as a soft key on the botton when you go into work offsets (similar to Dynamic, but with a different name - can't remember exactly what though).

My guess is you will not have it if you have G54.2
