Abstract

A new generalized model for the explicit evaluation of the total orientation and position errors of a multi-axis machine expressed as a function of its associated error components is introduced and a sensitivity matrix for each error component is obtained. Assuming that the errors, consisting of systematic and stochastic components are measurable, cancellation and minimum variance feedforward control algorithms in conjunction with an adaptive feedback system were proposed for error compensation. Simulation results for a three axis horizontal machining center indicate that potentially substantial error reductions at the tip of the tool are feasible.
