rotart drilling

[KMI]

I'm sure this is very simple but I cant seem to get it to work right. I'm simply trying to get the machine to drill a hole then index 15 deg and redrill a hole and do this all the way around a part. This is on a Mori horizontal. Any quick suggestions.

Use transform toolpath rotate by toolplane with the top wcs zero as your rotate point.

 

[KMI]

Thanks,

 

That works but now my post is giving me an issue. It is outputing everything as a A move instead of a B rotation move. Any suggestions.

Ahh,

Are you using the front tool plane as your B0.

That is the one you want to use for horizontal 4-axis programming. Right plane is B90.0 Back is B180. and left is B270.0.

 

What post and machine def are you using?

[KMI]

It works fine in the Mastercam. I did use the front tool plane but the code comes out with a BO move then lists a bunch of A moves without unclamping and reclamping the B axis. We have a full fourth so manybe it doesnt have to reclamp. They must be a switch in the post that is not turned on or something.

Hey Daryle,

You must be transform rotating around the wrong axis. Could you post a file on the FTP or send it to me?

 

Make sure top is the view you are rotating about.

 

I think it defaults to source operations tool plane.

Here is the post error I am seeing. "Only single-axis rotation is allowed!

Angles may be incorrect.

I was rotating in Mastercam correctly I think. I looks perfect in the verifier.

I have never seen that one. What type of machine and post are you using?

[KMI]

I have a Mori Seiki nh4000 with a 6 pallet cell. The post was modified when we purchased this machine from our old Takumi Seiki machines. Have never had a problem before and I'm sure it is a simply fix once we find where to fix it.

Yeah doesn't sound like a post problem. I am stumped unless I could actually see the file.

It sounds like you have everything set up right.

 

Good Luck,

"Only single-axis rotation is allowed!

Angles may be incorrect."

I get that error with my horizontal post when I program a job using an indexer mounted to the "B" axis, kind of 4-1/2 axis. BTW the code is fine.

I think that you are transforming around that 5th axis, You can check the machine def to see how the axis is set up.

The resin it does not work is mastercam does not support "Rotarting" for retards.. LOL

Hey Cadcam,

 

Was that supposed to be some sort of joke? If it was I dont get it. I use this forum to help me make my business more efficent, same reason I bought Mastercam in the first place. If you know how to help me out great I would really appreciate it. Typing fast sometimes equals spelling mistakes. Here is what the post code looks like: N100 G20

N128 G80

N130 G56 X0. Y0. Z2. A-150.

N132 Z4.5 etc.

 

Maybe it will work just wanted to make sure.

Yes it was a joke and I do understand typing fast and making mistakes do it all the time. And yes I know how to do what you want. here is my code.

More to follow after I take my family to dinner.

Good Morning,

 

It ended up being that since I have had mastercam for so long the post I had was preety old and really needed to be updated. I updated the post and Ajmer from In House walked me through making sure the correct lines were active. It works but it still needs some post help. It drills one hole then retracts,stops the spindle,indexes and restarts all over again. I needed to get the job done but it needs some work. The post also didnt output a M160 line at the end of the program and my horizontal needs it. Thanks for the help.
