Absolute and incremental dimensions for turning and milling (G90/G91)

The two following figures illustrate the programming with absolute dimensions (G90) or
incremental dimensions (G91) using turning and milling technology examples.
Milling:
Turning:
Note
On conventional turning machines, it is usual to consider incremental traversing blocks in the
transverse axis as radius values, while diameter specifications apply for the reference
dimensions. This conversion for G90 is performed using the commands DIAMON, DIAMOF or
DIAM90.
