Abstract

A digital controller for a closed loop computer numerical control machine demonstrating precision and rapidity in machining a given contour is proposed. The digital controller contains a digital filter which generates a copy of the reference input and the load torque disturbance signals. The reference inputs are both analytic and piecewise analytic signals. The closed loop system is stabilized using a digital stabilizer. The mathematical model of the process considers the lead-screw dynamics and the axial stiffness. Hybrid simulation of machining is used to compare conventional with proposed controllers. The effects of nonlinearities, noise, and parameter variation are considered in simulation.
