Sub-Spindle Programming in Mastercam

[Rotary Ninja]

I just made my first lathe program. I thought moving the part and stock to the sub side would be fairly straight forward. But I am not sure what to do to get Mastercam to do this. My jaws are on the left side of the part. Do I need to use another machine definition and just setup my WCS for D+Z- or something? I have seen the flip stock toolpath, but I have no idea how to use it. But I think I would rather run this part on the sub side instead of just flipping it.

 

Thanks

Hi Ninja, I've never done this before in mastercam either and don't have time to investigate at the moment, but id probably be looking at the stock transfer toolpath under misc ops

Yeah, I downloaded the Mastercam sample files and was just trying to figure that out. I hate lathes LOL

[uncle_dolan]

Lathe took me a little while to get used to. It didn't take long to work out how to create toolpaths, but there are a lot of cool things you can do to tweak the toolpaths and get them running just the way you want. There are quite a few options and I've always found them to be very customisable...have to fiddle with geometry sometimes though.

I got it figured out. There is no way in he## I would feel safe running it. But verify looks right

There are several different ways to do the Sub-Spindle/Stock Transfer. First, you must be using a Machine Definition with the proper Axis Combination to support a Sub-Spindle.

 

You must also modify your post to support either the regular "stock flip or stock transfer", or the new Pickoff/Barpull/Cutoff (POCO) routines.

 

The nice thing about using POCO is that you can see each individual "chuck" operation for each step in the process. It makes it much nicer for verifying your pickoff operation.

I am just doing this at home in the Home Learning Edition. So posting is not an option.

So it is under the misc. pick pull part. select the one you want. But you will need a machine def with both spindles defined. the set your wcs for the sub spindle. PM me with any questions I'll be glad to help you out.

Also, you will have the from and to option. note that you have to know the thickness of your jaws or it won't look right in verify.

[Rotary Ninja]

Haven't tried that one yet. Thanks for the info. Will try it out tonight.

[The_kid]

if you want to send me a file I can do one up for you and then you can go from there. I want to do a chess piece set would be very fun.

Ok so for your WCS it is the D- Z+. for face milling main spindle use right. and use back view for outside milling. still -D Z+ for sub only diffrent work offset number. Sorry didn't read the eintire post before response.

Yeah, I think I got that figured out. It is still a bit confusing. I will have to do more lathe programs to get it all figured out I think.
