1.10.1 Tool Length Compensation in Tool Axis Direction with Twin
Table Control
Overview
For a machine that applies twin table control to two heads, tool length
compensation along the tool axis can be performed simultaneously for
both heads (synchronous operation) or for each head (independent
operation).
In synchronous operation, the compensation value calculated using the
rotation axis positions of the master head is applied to the linear axes of
both the master and slave heads.
In independent operation, the compensation value calculated using the
rotation axis positions of the selected head is applied to the linear axes
of the selected head.
- Sample machine configuration
This function is explained using the following axis configuration as an
example.
