Analysis and Control of Multi-Choice and Non-Linear Error for a Spindle-Rotating Machine

The mechanism model of a spindle-rotating machine is proposed in this paper according to the mechanism theory.The movement model is established using coordinate transformation,and the solving of this model is discussed.Based on these,efficient algorithms for multi-choice and non-linear errors have been presented.A dedicated post-processor with non-linear error compensation function was developed by VS2010 language.A circle frame cutting experiment was conducted and the result showed that the algorithms was correct.
