Mori Seiki Lathe cl2000

[cqualls]

Which default post is the best one to start with on a Mori Seiki CL2000? We are using Mastercam X Mill 3 with lathe. The Lathe is a 2 axis In and out is x and cross travel is Z.

Thanks,

MPLFAN is a very good starting point.

 

MPLMaster is pretty good too, started an Mori SL with this post the other day, almost done.

I'm using the MPLFAN pst. When Cutting a round piece of stock that should finish at 1" Diam. and shoulder down to 1/2" diam. the finish dimensions of the stock is coming out to be 1.032 on the large diameter and .780 on the smaller diam? Is something in the post causing this. It verifies correctly in the backplot on mastercam 9.1

What does the code say?

[cqualls]

The code shows everything right.

I now have 3 steps in the part: .5 ; 1.0 ; 1.5 diam. The part finishes at .780 ; 1.032; 1.280

I'm new to this lathe stuff. It appears to be some kind of setting or something in the lathe(It is a Mori Seiki CL2000)

Can you put your file on the FTP?

[cqualls]

Its in the MC9 folder named Lathe_Test.

Ahh, the old 'turn random diameters' setting...

 

If the code is right it ain't a post issue

 

You are turning 3 straight diameters with the same tool and they aren't consistently oversize / undersize?

 

Something radically wrong there...

[cqualls]

Same tool and same tool path. It would appear to be some kind of setting in the Lathe itself to me but as I said before this is the first time I've done any cnc lathe work so I know nothing cnc lathes.

I looked at your file and there is nothing there that would cause what you are seeing
