Cutter comp activating/deactivating

[Lord Wukits]

The joke around here is it happened yesterday(Wednesday).

I'm using Mastercam for Solidworks X9, and the machine definitions are for Mazak, and the default Hass 3 axis. Same issue with both.


I was making a pocket, but noticed that mastercam doesn't want any wear/cutter comp for these tool paths..... so I rough them out with open pocket... and use contour to finish(with wear). THe code I am getting is;

As you can see the cutter comp/wear id turning on and off.. then appears to be moving to the "new correct location" it should be at with cutter comp/wear off. Adding notches/humps in the part.

Any idea what's going on? 
Attached is the generic Hass 3 axis nc but extension changed to txt as these forums won't accept the .NC extension (Not surprising but really?!)

~~~~~~~~~~~~~~~~~~~

nOONE USEs COMPENSATION FOR pocket roughing for  a   couple of   reasons

but if you would switch on finish in the same pocket operation you can use compensation without a problem.

I do not want to enter into the reasons why noone uses compensation for pocket roughing (except may be some parametric and build in programs )you can get into it by yourself.

SO for clarification I need to run two tool paths. One for roughing, and one for finishing?  I had originally tried to run a finishing path/depth as one toolpath and the option was not available.


That would be/is great information, but why is cutter comp getting turned on and of on and off, with x/y movements in between?

[Teh Bear without Brains kinda idiot]

You can run finish inside pocket ,

You need to switch on finish subpage

So you`ll have roughing without compensation and walls finish with it in the same toolpath .

But usually I prefer separate tools for roughing and finish for my kind of work

As for why

, but why is cutter comp getting turned on and of on and off, with x/y movements in between?

~~~~~~~~~~~~~~~~~~~

You need to learn more about cutter compensation how it works and it`s limitations

If you have some fanuc machine Fanuc yellow book (one of them ) Has the best

explanation of compensation ever been written  IMHO

Just understand how it works then read about all limitations of compensation and you`ll get it

If you can, upload your file..
i'll check it out this weekend.. 

A pocket toolpath should not be doing that..

Is is possible someone has been messing with the post???

I just noticed I have NO cutter comp on my Open Pocket toolpath.  Am I missing something?  Bug? I do have "Finish" checked on.

 

 X9, no updates applied I believe... maybe the first only.
