Mastering Siemens Sinumerik: DIAMOF, DIAMON & DIAM90 CNC Lathe Commands

Sinumerik DIAMOF, DIAMON, DIAM90

CNC lathe X–axis (transverse axis) is programmed as diameter dimensioning. When necessary, it is possible to switch to radius dimensioning in the program.

DIAMOF ; Radius dimensioning

DIAMON ; Diameter dimensioning

DIAM90 ; Diameter dimensioning for G90 and
       ; Radius dimensioning for G91
