See "Feedrate (G93, G94, G95, F, FGROUP, FL, FGREF) (Page 111)" for
information about G94 and G95.

: Deactivate constant cutting rate with feedrate type G94
: Deactivate constant cutting rate with feedrate type G94 or G95
: Deactivate constant cutting rate without activating spindle speed limitation
: Speed limitation for the master spindle (only applied if G96/G961/G97 active)
On machines with selectable master spindles, limitations of differing values
can be programmed for up to four spindles within one block.
