Modeling, control and simulation of high speed machine tool axes

Deals with the modeling, simulation and numerical control of a high speed machine tool axis. The dynamics of rigid bodies, the elasticity of bodies and mechanical transmission, the dynamics and saturations of electric actuators, the effect of numerical control as delays and quantization are considered for the simulation. The cascade IP speed loop and P position loop controller are computed using a frequency approach and an optimization procedure taking into account the lumped model and the effects of digital control. Experimental results on a real machine tool axis are also presented
