how do these machines manage to anticipate the amount of twist and warp in the board before it mills the wood, so as to average the removal top & bottom, and side to side, and produce the final perfectly planed piece?

Most of them don’t anticipate anything. An experienced operator is the ‘anticipator’. How they operate isn’t all that complicated for the most part. It’s nothing more than a power fed 2 headed jointer(bottom and right head) that also incorporates 2 other heads for thicknessing(left and top). Set the required depth on the bottom table and the fence on the right hand side(infeed side). Set the left hand head and the top head for final dimensions.
These machines are pure production in the sense that they’re meant to be set for desired removal, which may be anywhere from 1/4” to 1/2” depending on the machine and the condition of the rough material on average and then fed continuously for perhaps hours.
If you set the machine and ran a piece that was considerably more twisted or warped than the average piece you set it for, it wouldn’t come clean. An experienced operator would foresee that and that material wouldn’t be fed into the machine at all.

Most of these machines are manually adjusted to the proper dimensions, but this one is a little more advanced.
Weinig are the leaders in moulders.
