Changing fixtures and reposting program.

[Jon @ NOWHERE]

We've been running some parts on regular vise jaws, when we recently decided to use a different set of vise jaws to help prevent pulling the part out. The new jaws move the part over in the x direction around .500" and up in the z direction around .300".

How can I change this in mastercam and repost without having to reprogram everything? This can't be done with fixture offsets alone as there are 4 axis tool paths. Using X3 MU1.

 

Thanks

Couldn't you reposition in the WCS.......

[Jon @ NOWHERE]

Well I tried that and it didn't really seem to help the z, when I program I use absolute instead of incremental so I am not sure if that would change anything or not.

That would depend on how the program is setup. If you use part zero then all you'll need to do is move your part/geometry and your plane origin locations. If you use the rotary zero and your programming incremental then just moving the part/geometry will do it. If you use the rotary zero and your programming absolute then you're going to have to move the part/geometry and shift your "Z's".

[Jon @ NOWHERE]

That is what I was afraid of, we use rotary zero and absolute programming. Just wish there was a way to mass modify all the parameters(like adding .300" to all retracts, feed plane, top of stock and depth).

Makino man, what kind of Makino is this on? Do you have dynamic compensation?

[Jon @ NOWHERE]

Its a Makino A51b. Professional 5 controls. I'm not sure if has dynamic compensation or if we even have it turned on if it does.

[Joe788]

If you guys are doing lots of simultaneous 4 axis stuff, the dynamic comp option would pay for itself very quickly. (Makino might call it something else, like tool center point control, or something similar. I'm quite certain the option is available if you don't already have it).

 

You'd just enter in X.500, Z.300 into the dynamic comp register, and Bob's your uncle.

Sounds like something I need to check on then. Thanks
