7.1.11.2 Automatic feedrate control function
In AI contour control mode, the feedrate is automatically controlled
by the reading-ahead of blocks.
The feedrate is determined using the following conditions. If the
specified feedrate exceeds the determined feedrate, acceleration/
deceleration before interpolation is performed to achieve the
determined feedrate.
<1> Feedrate changes on each axis at a corner and the permissible
feedrate change that has been set
<2> Expected acceleration on each axis and the permissible
acceleration that has been set
<3> Cutting load that is expected from the travel direction on the
Z-axis
Specified tool path
Tool path assumed when
l contour control is no
used
Tool path assumed when Al
contour control is used
The machining error is decreased
because of the deceleration with
the acceleration.
The machining error is decreased
because of the deceleration by
difference in feedrate.
