Turning

[sennakyro]

Hey I have drawn a tube to turn, the tube is 14 mm in diameter and the stock is 0.5 mm. The maximum depth of cut is 

0.25 mm; I use Fanuc as post processor. In the code the first cutting depth is 14.75 mm, it should actually be 7.375 mm. 

Is there a setting error

Are you expecting a radial value? What is your machine and control, most modern controls work in Diameter value.

Is this OD or ID work, can you share your file here?

Hey my lathe is from china, I rebuild it to cnc. My control is UCCNC . My post processor is Funac. The attached file is a tube with diameter 7 mm and and a part of it is 5.5 mm. When I turn it, the diameter is 14 mm and 11 mm. I think it is a setting but I can't find it.

Thanks for the reply

So it sounds like your controller is looking for radial values. Is it possible that there is a setting on your controller that will allow you to accept diameter values instead?
