I have a Hwacheon Hi-Tech 200c lathe with a Fanuc Oi-t control. When programming G01 moves it will automatically round off the corners, which in some cases comes in handy, but sometimes I just dont want that. I'm not using a tool nose radius comp. I learned that all I have to do to make a sharp corner is to just put a blank line in the program between the two moves where I want a sharp corner, but the problem comes in when I want to program a certain radius. Lets say I need a radius smaller than what the control is giving me automatically, but not a sharp corner, im stuck.....

Is this a G code? M code? something in the parameters or what? My other machine doesnt put and radius on the corners unless I program is to do so.

any suggestions are appreciated.
