Offset Diameter Cam Turning/Milling on Lynx 2100
Hello, Anybody got some Ideas on this?
I am having trouble programming a .250" offset 1.5" +-.006 Dia on 2" OD, on our just purchase Doosan Lynx 2100LYA. Getting .07" out of round. I am trying to do this with a vertical 1/2 endmill with a R.03.
The E-Z I software on the control wants me to do it as a live tool face, but with the tail stock and clamping less than 3/8" deep on a hex and my offest diameter starts at -1.625 and finishes at -2.875" , it rules that out as a possibility.
The strange part is I use a 1/2 Ballnose endmill and i am getting .030" out of round, I tried using a 1/4" 90 degree point endmill and its only out .002" Tried a CMNG insert and turning it, comes out perfectly round too, but taking out all that material, I am only pushing 1/8" DOC and .005 stepover, I am pushing the head as fast as it rotates but it takes a lot of time, as I am doing a lot of these pieces.
I also tried mucking about changing the rad in the program but if I increase or decrease it, I get some pretty cool egg shaped designs.
It's like I almost have to program some kind of tip comp in.
Also included a pic of what I am trying
I got a program off this forums and modified the diameters.

Thanks for any input, as I am new to programming lathes, and my company decided I'll be the one they throw in head first to learn it.

Do you have the classroom manual?
I wrote them way back when I worked for Doosan, and I'd be glad to send you a copy.

No I don't I just have the ones that shipped with the machine and what is on the flash drive. Thanks for the help.

Figured it out, kinda hard to do manually, The cutter either cuts on the front or back tip, which throws me out of round. Got a buddy to post out something for me. I'll share it if anyone wants it for reference.
