I dont see why not. It can control four axis, and you have Acceleration and velocity settings. I think you could translate feed to speed with a tach.
20 IPM = ?RPMS
Not sure how the program would be written G9999 F- A(axis) to infinity until stop.
I dont know if it can be run under the spindle settings tho. That would be cool.

Yeah this wouldnt work. I dont think the other axis would move, waiting for it to catch up.

General Mach Discussion / Re: Lathe CSS again

« on: January 27, 2017, 08:38:01 AM »

I use CSS with IPM feed on aluminum & it's better than with a fixed spindle speed...sorta.  I was parting off some 2" diameter bitchy steel a while back & took the time to figger out the correct feed rates for the decreasing diameters in 1/8" intervals.  I added those feeds into the code manually & the results were better.  Life lesson:  Don't eat the yellow snow or part-off big, bitchy steel on a little lathe.

I'm not smart enough to write an Excel sheet that would do it for me.  Surely that'd be a piece'o cake for one of you 'puter experts?

Thats a good idea. I was watching a Sandvick video the other day and they suggested slowing your feed rate by 50-70% about 1/8"-3/16" from the center for parting. I have'nt tried it but makes sense, and about where mine starts sounding grumbly.
I've been parting 1-5/8" 6061 alluminum, with an upside down HSS/COBALT cheapy in a BXA tool holder at 500sfp with a feed of 3 ipm. It runs from 1600 rpm to 1800 (max)rpm.
Parts beautifully with a glass finnish. 6' long stringers tho. Sharp as razors and pretty strong.

You're right. Not that big a deal. My Cam cost a lot more than Mach3 did.
I find myself getting a little obsessive over the little things sometimes. CSS isn't the end of the world.
I never had it on my manual lathe. Probably why I like it so much.
I still use it with IPM. Works ok for what I make every day.
Sorry for being grouchy, Jerry

Kinda irks me about the lack of finishing up on turning part of the software.
I couldnt even get a simple reply on this which I finally found the answer. NO IT DOESN'T WORK.
It should be FREE for Lathes.
I'm thinkin I should just stick with $50 computers and Linux.
Why spend money on software that doesn't work properly, or isn't updated anymore?
Time for another cheap computer from ebay and try it myself. It runs my mill fine, just thought I would try seeing why people were buying this.
Now I know.Scared to try O.S. other than Windows computers. It's really not that bad

Not sure if this is what you need.
Configurations - General config - Active plane of movement, check XZ
If a gcode is already loaded, you have to unload and reload for it to take affect.

I got my posts to work by adding G90.1 (arc center absolute), and checking reversed arcs in front tool post under Turn configurations in Mach3.
I was getting Crop circles:)
