General Mach Discussion / Turning wizard says 0.75" but part ends up 0.5" diameter
« on: August 11, 2017, 01:29:40 PM »
Hi, here are the steps I am talking to use turning wizard. I start with a 1" dia piece and want to turn to 0.75" dia but it turns to 0.5" dia
Diameter Mode
Home machine
Touch off piece and place at edge
Place 1" in x and click part zero
Place 0" in zed and click part zero
Go to turning wizard
Place 1" in start x
Place 0.75" in end x
Place 0" in start zed
Place -0.25" in end zed
0.010" rough cut
0.005" finish cut
0.1 clearance
Post code
Go to auto, cycle then cycle start
Cuts to zed -0.25"
however x is cut to 0.504" instead of 0.75"
What is normal backlash? Could this be affecting it.
When I touch off and set on edge and move just off face and then G1 X0 tool goes to other edge not center of piece at 0.
Why? I though zero on lathe is center of object being turned.
Help, What am I doing wrong?
Thanks
Dave
