C axis Circle Interpolation

[westerfieldc]

Hey all, I know I have seen this before but I cannot remember what the fix was. When I post the code for this I get a bunch of X and Z moves instead of G02 or G03 codes. It doesnt matter if I use Lathe C Axis Face Contour or just Milling Countour.

 

Thanks

Need to enable the G107/G112 switch found in the Misc integers (usually number 4)

Thanks for the responce I tried it and it didn't work. I should say that I'm using the Mastercam VTL post.

 

Thanks

Are the Settings correct in the Machine def manager/general machine parameters? Try changing the orientation setting under the Cplane tab....

_Hi,

 

_{I am having the same problem, I have g107 enabled and when I post, I get a bunch of C's and Z's}

 

_{@Chris Bloedorn: Which setting specifically are you referring to? On the cplane tab, all looks good for the orientation setings.}

Are you ramping? If so, in the cut parameters page, where you set ramp data is a "Linearize helixes" that some times gets checked.

If you change your WCS to top and you T/C plane to right side or left side, depending on the spindle you are using. Use the milling contour XY, not C axis lathe.

@jayemvw : What do you mean by "ramping"? I am using mcx8, I do not see such parameter in the cut parameters.

On a C axis Toolpath there is Contour Type just like Normal Contour in Mill has if you were using a Milling toolpath. You change the contour type the dialog changes to support ramp for the toolpath. Using it on a Multus U4000 and works slick. I have Ramp with C Axis for years on Mill Turns and good way to get a lot of Material out of a part quick like.

Thanks a lot for the help but unfortunately, even after changing the contour type to "ramp", I still get the same posting results.

Arc filter may be?

A Z2G  would be the most help at this time, otherwise just tossing stuff at the wall and seeing if something sticks...

Are you sure you have your rotary axis set to C, and not Y or No Rotation?

[Dan@home]

Sounds like you need to allow Arcs in X,Y,Z. Go to your MD/CD.

I'm actually using Axis substitution under the "C Axis contour toolpath", It's some flat text that I have drawn that I wish to cross engrave but the generated code has no arcs at all and is overwhelmly long!

I wish to use the machine's G107 capability.

Arcs are enabled in the MD/CD

G107? What kind of machine are you running? If it's some kind of mapping function or rotary interpolation, most likely the reason you're not seeing the code you want is because the post isn't set up to output it.

Have you looked at the mi or mr if using standard lathe? In the MT product that will be in the consumer settings to turn that on or off.

 Sorry I'm not too advanced with mastercam nor it's terminology, what is mi and mr?

They are called misc values. They are switches used by most posts to control different outputs needed like what you are needing here. I would suggest getting a hold of your local dealer and having them help you sort it out.

 

Never mind about the MT product.

Thanks a lot to all for the help, at this point I guess I have no other option than to contact my dealer.
