using a vise and a workstop. You see, my machine profiles within +/-.001 or better, couldn't ask for anything more. At the end and beginning of every program there is a rapid, and usually it loses a few steps there. So what happens is that zero is within +/-.015. Now lets say that my .125" end mill whos radial depth of cut is .007" and considering that error if we are at .022 radial then with speeds and feeds tuned to .006 rad DOC SNAP!!. I need to rezero for every part.
I am using a C32 board ESS and dugong DG2S16035 drivers. After these parts are made some one will be getting a nice deal on 4 26 in/lb SEM servos a Bridgeport power supply C32 board 4 drivers 3 brakes, and all the controller components for $2500 and I will be upgrading to absolute closed loop controller, on the fly tuning AC servos motors. I have had it with what I have.
