Last couple days I have not been able to get out and work on my cnc lathe , so made myself a promise I would get out there today and get the following accomplished.
1) get lathe wired into control panel
2) get computer moved out to shop and wired up & connected to control panel
3) troubleshoot the limit switch error that crept up on me before the move out to the shop
4) plan my part cuts , which is for an encoder wheel for my spindle so that I can get spindle speed indication
5) load and set my tooling (facing tool, boring bar, turning tool, and part off tool)
so after all that I chucked up a 2.5" piece of round stock and proceeded to generate and run a face off program. Then loaded tailstock with pilot drill. I drilled pilot hole, then enlarged it to 3/8". Next I generated and ran the boring program for enlarging the 3/8" hole to 1.04" and a depth of .08 . I followed up with a scribe mark for the encoder hole locations (mark located at 2.0 dia. I then generated my turning program, and turned the outside down to 2.2" for .12" . All this went smoothly, but part off wasn't a nice easy cut...having problem with worn spindle gears, so it took forever to make the parting cut. At one point I switched parting tools, and my other tool cut a bit better but not much. Pics below are my CNC converted mini lathe, the stock I made my part from, the part from right, the part from left, and the part head on showing the 0.04" thickness.
The encoder goes in between the two nuts on the spindle shaft that can be seen to the right of the encoder in the last pic. I will get it mounted and hopefully get the optical encoder wired and working too
That my friends is my first CNC machined part, using my lathe to make itself better
