Hi everyone

I am programming SUPER NTJ NAKAMURA Lathe and this machine is twin spindle one turret at the top other one bottom right hand and upper turret is with Y+B AXIS so we are doing all kind of milling on that machine. I was wondering if there is any way to TURN DIAMETER OFF
Like Siemens or heidenhain. Yeah one more thing this machine has macro B Option. SO if have any info pls let me know
Thank you in advance
