I’ve used TurboCAD on the mill for a few years at home on V17 and have recently started using it on a ’91 Hitachi lathe my work acquired for cheap (free, our other store couldn’t figure out how to run it). My work then bought the latest V18 of TurboCAD/CAM to use for the Lathe (Which put me under a little stress that I had to figure it out now)
First of all let me say that the CAM portion of TurboCAD leaves a little to be desired, and I really don’t think that the CAM portion of TurboCAD/CAM has been updated since they first introduced it on V12, but I think for the money this might be the only way to go if you want a single program to do everything. (I’m sure I’ll get beat up for that remark, but I’ve tried some of the other programs recommended on these forums and haven’t yet found one that I would consider overall better)
Anyway, as far as cutting for a lathe goes I noticed that you have to use one of the 2 setup machines (in the CAM setup Wizard; either the “Fanuc-Lathe” or the “Tormach-Lathe”) and modify them for your machine; if you try to save to a new machine name it won’t do some functions like threading for some reason. Next as you’re going through the setup wizard when you get to the “Part Geometry” the “Length” and “diameter” has to be the same size as the shaft you’re starting with.
Then when you draw your shaft and place it to be turned you have to put X0.000 and Z0.000 on the screen so that X is on the centerline of your shaft, and Y is also on 0.000. (You’re going to notice that X and Y in on the screen is backwards from the Lathe X and Z, “Y” on the screen is the “X” axis on the Lathe and the “X” axis on the screen is the “Z” axis on the lathe)
After you put your shaft on the screen, what I do is draw a “cutting line” with the polyline tool and the most important part is that the cutting line needs to intersect the part geometry line. (To draw simple shafts I just make them out of separate blocks, and then put the radiuses in after I draw the cutting line)
I’m going to try to post some screen captures to try to show the process that I use, this may not be the “right” way to do it but it works for me.
If you've noticed this polyline doesn't look the same as the shaft in the previous pic I put the radiuses in after I draw the polyline (I've hidden the original "shaft" after I traced it with the Polyline)
Then you use the turning tool and click on the part first, and then the hashed area you want to remove. (Note that if you can't get it to do anything then your "turning line" may not fully intersect your "part Geometry" line)
After that you hit the Finish button and it makes your cut.
Hope this helps, this is just the way I do it and may not necessarily be the way the "experts" do it
