MACHINING PROGRAM 4
4-11
7. B-axis positioning
Perform B-axis positioning.
If the B axis is already indexed, it is not necessary to command B positioning here.
For turning, command B axis clamp (Turning spindle does not turn if B axis is being unclamped).
8. Spindle rotation command
Command a rotation for Turning-Spindle/Milling-Spindle. M-codes are shown in the figure below.
S-address means rotational speed (G97) or surface speed (G96) by modal G-code group 17.
In case of Mill-machining, G96 cannot be used.
When G96 is used, command G92 to set the maximum min
