I guess I'm missing something too. I've done a significant amount of 4 sided tombstone work myself. If you're using C.O.R. why are you probing? To use C.O.R. on a tombstone you must have the spec sheet from the tombstone maker and program accordingly in mcam.

 

If you want to probe and use C.O.R. you can probe points on the tombstone for G54.4/G54.2 dynamic offsets which will calculate deviations for you. Or you probe each face for a unique offset (G54, G55, etc).

 

You can also probe one face of each part and use G68/G68.2 and let the control calculate rotations for you.

 

There's more than one way to split the wig but you gotta pick one.

 

I like G68.2 for 4 sided work because you can probe the center of every part for its offset then when it rotates the machine will calculate the same point when its rotated.

 

Are the parts located on the tombstone with locator pins or are they just bolted to it (this is how I would decide what to use)?

They are located with locator pins and held down with swing clamps.

I was hoping to be able to use COR programming while having the bore probed and machined perfectly on center, even if that means its programmed separately.

Hi Leigh (its Colin, BTW.) The post was created by In-House based on MPMaster. I hopped into the first operation and found that it had been flagged as 1. Just changed it to zero, and that's solved my offset update issue. Thanks!

"I have a 5" tombstone with 4 parts on it, ..."

 

A picture is only worth 1000 words. An MC file s worth a million. Post your file here.

I unfortunately am unable to post the file publicly, or I would, if you would like to take a look, PM me your email.

So I've created all the planes and made a separate group with a copy of my toolpaths. Now the problem I'm finding is that Mastercam is not posting my new work offsets per indexed face.

Example:

And yes, they have offsets in the Plane manager

Hmmm.

Wow, that was truly extensive Colin. (oddly, I have the same name, hooray for single L Colin's!)

I was hoping to be able to still include probing and work off the center of rotation, but it seems like Colin's way is the way to go. I've made a working copy and I'll give that a shot today and see how it goes, I don't expect any problems.

Thanks everyone for all the help, I'll report back later.

Hmmm, okay. I'll play around and see what my local support has to input on the matter and post what I come to. Thanks all for the information.

Are you certain that it's the program? Is your rotary table proven to be accurate and working? 

Its definitely functioning. If it wasn't I wouldn't be here. It does run other programs successfully, although I have yet to program with this style of one-origin programming.

I would use a work offset for each station.  Then use G10 to write the offsets in.  That way it is still a fast setup without needing to set a XYZ for each station, but each station can still be adjusted if need be by the operator.  Set the work offset for each view in the view manager.

Yes, that's a good way to do it, but you seemed to miss the point of my question, in that I can't get it to rotate correctly.

Hey guys,

Firstly, yes, I have searched the forums and tried many different ways to get this to work, and I feel I'm just missing something simple that's affecting the whole process.

Machine is a Haas EC400.

I have a 5" tombstone with 4 parts on it, two per face on opposing sides, B0. and B180. The parts need to be hit from their relative front face (0deg) and both sides (90 and 270). I've programmed the part with the top plane at the center of the tombstone, and each part also has its own offset for their B0. center and top surface.

For instance, G55 is set at 2" from the top of the base of the tombstone, and the center of the tombstone, and G54 is the center of the bore that you see that has the toolpaths associated with it, with Z set at the furthest point from the tombstone.

G55 = Top

G54 = Part Probed origin

I have the WCS for all operations set to TOP.

I have the T/C plate for all operations set to their respective planes that I have created off of the geometry from the part. This was done by dynamically rotating the G54 plane to be oriented correctly, so the centerpoint is still as-described for G54, just reoriented.

Those rotational planes have their work offset set to G55, is this correct? Should it be G54, even though the WCS is still for TOP?

When I try to run the code, it trips a limit or otherwise does not drill where I want it to. Should I be using the right/left planes that already exist? Should the side planes be set to G54 (the probed part offset) or otherwise? Does anything stand out? Because right now I'm just lost for what to do.

Thanks!

No, no 2016 beta has been installed. I've played around with the settings for solid import and it seems to be working fine for at least .sldprt files, but I cannot for the life of me import an assembly file.

EDIT: I had my IT tech come down and the fix worked! Thanks!

Is anyone else having this issue? It immediately crashes on me.

Hey hey! That worked!

Now to find how to change the edges from being red, but whatever, it worked! Thank you!

It was surface grid lines that I was thinking of. Fix was a video card setting of some kind.

Hmmm. Okay, Ill poke around. I went back 3 months and couldnt find anything directly related. If anyone else has more suggestions they would be greatly welcomed.

Look at your config, solids, line width.

I have it set to the thinnest line.

Hey there,

I just had my workstation replaced, and we swapped drives over, and obviously at some point my settings went a bit wonky. Now when I open my old programs in Mastercam (X8) the solid edges come through with very, very thick lines. I've tried clearing colours, and looked through the help and menus for something that would make them thinner, or preferably remove the highlighting altogether. Any ideas guys?
