Lathe Question

[John Spangler]

Hi

I have a question, since i'm brand new to Mastercam Lathe, and turning centers in general.

I am modifying an existing program, for an id bore, and on the longhand written program all my X moves are positive. In the mastercam post all the X moves are negative. Using Canned cycle rough and finish, G70 and G71, have the geometry chained and drawn correctly (Pretty sure) and the correct tool, tool turret, etc. selected. Everything matches my existing program, except for the X moves.

The machine is a brand new Haas ST30.

 

Thanks

John

Are you drawing and chaining the geometry above centerline or below? Should be above.

[John Spangler]

Yes, It's above. My origin is at the center in X, and the far right at Z. I drew half the geometry (radius) and mirrored it, for reference. Picked the Chain I needed to work on, on the X+ side. What is confusing is that it backplots with the same motion as the longhand program runs, and the long hand program is X+. Mastercam = X-.

Are you using the GENERIC HAAS TL 2X LATHE Machine Def?

 

Try using the GENERIC HAAS SL 4X MT_ LATHE instead.

Hi

Yep, tried both of them. I'll try it again.

The Tool Nose Compensation thing is killing me, trying to figure these longhand programs out and modify them!!

Ugh!!

Nothing matches the prints (as far as code).

I've been putting reference numbers in comments, so I can at least see where i'm supposed to be, but If I could do these in Mastercam, it would be SOOOOOO much easier. Well, for me, at least.

Thanks

Leave your comp at "computer". I never use comp in mastercam, If I write a program by hand, sometimes I will use comp.

Well, I guess you could post a small pc of code and some pic of the part if you're allowed to that way we can tell you what you should be getting off of MC.

 

BTW, Did changing from the TL to the SL machine def fix your X- values to positive numbers?
