Turning:
Note
On conventional turning machines, it is standard practice to interpret incremental traversing
blocks in the transverse axis as radius values, while diameter dimensions are valid for
absolute coordinates. This conversion for G90 is performed using the commands DIAMON,
DIAMOF or DIAM90.
For dimensioning for diameter or radius, see circular interpolation G2/G3.
