8.11 AI CONTOUR CONTROL
Overview
This function is intended for high-speed and high-precision machining.
The use of this function can hold down the delay due to
acceleration/deceleration and the delay in the servo system, which
increase as the feedrate increases, reducing the machining profile error.
This also enables linear acceleration/deceleration before look-ahead
interpolation with the look-ahead of up to 40 blocks, achieving
smooth acceleration/deceleration over multiple blocks and permitting
higher-speed machining.
This function is limited to two-dimensional commands.
The following functions are enabled in the AI contour control mode.
(1) Linear acceleration/deceleration before look-ahead interpolation
(look-ahead of up to 40 blocks)
(2) Automatic corner deceleration
(3) Feedrate clamp by acceleration
(4) Feedrate clamp by arc radius
(5) Block overlap (usually five blocks, up to 40 blocks depending on
the parameter setting)
(6) Advanced preview feed forward
For details of the above functions, see the descriptions of the
respective functions.
