- Switching between synchronous and independent operation
(1) Synchronous operation
Tool length compensation along the tool axis performs simultaneously
for both heads.
The compensation value calculated using the positions of the master
rotation axes (B and C) is applied to the master linear axes (X, Y, and Z)
and slave linear axes (V and W).
(2) Independent operation
Tool length compensation along the tool axis performs for only one
head.
When head 1 is selected, the compensation value calculated using the
positions of the head 1 rotation axes (B and C) is applied to the head 1
linear axes (X, Y, and Z).
When head 2 is selected, the compensation value calculated using the
positions of the head 2 rotation axes (J and K) is applied to the head 2
linear axes (X, V, and W).
- Switching between synchronous and independent operation using the
miscellaneous function
Specify the program command miscellaneous function in a single block
to switch between synchronous and independent operation.
Set an M code to be used in the corresponding parameter, listed below.
