Full Description

High speed machining consists of three major components: fast spindles, fast feed rates, and the ability to follow complex profiles accurately. This paper describes what the controls do internally in order to follow these paths at high speed. It includes a description of how it used to be done, what was wrong with the old way, and a detailed description of how it is done now, as well as a description of acceleration before interpolation and look-ahead and a discussion on controlling accuracy. The mathematics of how many blocks per second are required is covered along with how many blocks of look-ahead are required.
