7.2.3.8

Spindle control

D e scription
M3 :
Spindle accelerates to the programmed speed in clockwise
direction.
M4 :
Spindle accelerates to the programmed speed in counter-
clockwise direction.
M5 :
Spindle decelerates to stop.
M1 9:
Sets the spindle to a specific angular position.
For more information, see Section "Spindle movements (Page 109)".
7.2.3.9 Setting dwell time in the program (G04)
D e scription
G0 4 :
G04 can be used to pause the tool movements during ma-
chining process.
G04 F5: program dwells for 5 seconds
This makes the workpiece surface much smoother.
For more information, see Section "Dwell time: G4 (Page 108)".
8 Program simulation
Si mulation before machining
Before automatic machining, you need to perform the simulation to check whether the tool moves in the right way. During
simulation, the current program is calculated in its entirety and the result displayed in graphic form. The result of
programming is verified without traversing the machine axes. Incorrectly programmed machining steps are detected at an
early stage and incorrect machining on the workpiece prevented.
You can choose one of the following methods for simulation:
● Simulation prior to machining of the workpiece (Page 43)
● Simultaneous recording prior to machining of the workpiece (Page 45)
Si mulation during machining
If the view of the work space is blocked by coolant, for example, while the workpiece is being machined, you can track the
program execution on the screen. For more information, see Section "Simultaneous recording during machining of the
workpiece (Page 48)".
