When a machine has a manual gearbox on the spindle, it is the responsibility of the
operator to change gear at the correct place in the part program.
If the machine tool manufacturer has fitted an automatic gearbox, the following M-codes
can be used to change gear in the part program:
Gear stages M40, M41, M42, M43, M44 and M45 are available.
M40 Automatic gear selection
M41 Gear stage 1
M42 Gear stage 2
M43 Gear stage 3
M44 Gear stage 4
M45 Gear stage 5
Example:
The machine tool manufacturer specifies a speed range for each gear stage:
S0...500 Gear stage 1 → M41
S400..1200 Gear stage 2 → M42
S1000..2000 Gear stage 3 → M43
If the operator is manually selecting the gear stage in the part program, it is the operator's
responsibility to select the correct gear stage according to the required speed.
