Spindle speed G97 / G197
G97: Constant speed for the main spindle
G197: Constant speed for spindle 1 (driven tool)
Parameters
S:
Speed in revolutions per minute
Constant cutting speed G96/G196
G96/G196 defines a constant cutting speed.
G96: The speed of the main spindle is dependent on
the X position of the tool tip.
G196: The speed of spindle 1 (driven tool) is depend-
ent on the diameter of the tool.
Parameters
S:
Cutting speed in m/min or ft/min
Feed per revolution G95/G195
G95/G195 defines the feed rate as a function of drive.
G95: Referred to main spindle
G195: Referred to spindle 1 (driven tool)
Parameters
F:
Feed rate in mm/revolution or inch/revolution
Feed rate constant G94 (minute feed)
G94 defines the feed rate independent of drive.
Parameters
F:
Feed rate in mm/min or inch/min
Speed limitation for spindle G26/
driven tool G126
G26/G126 limits the speed. A speed limitation remains in effect until a
new value is programmed for G26/G126.
Parameters
S:
(Maximum) speed
• The speed limitation remains in effect even after concluding
the DIN program and exiting “program run“.
• If the speed programmed is greater than the speed set in
the machine parameter “General parameters for spindle – ab-
solute maximum speed“, then the speed limit of this param-
eter takes effect.
Interrupted (intermittent) feed G64
G64 interrupts the programmed feed for a short period of time. The
function remains in effect until you program G64 without parameter
definitions.
Parameters
E:
Pause duration – range: 0.01 s < E < 999 s
F: Feed duration – range: 0.01 s < E < 999 s
