Abstract
Productivity in ultra-precision (UP) cutting is limited as an effect of the demanding sub-micrometer requirements on path accuracy. In order to attenuate dynamic errors and the excitation of vibration, feed velocity, acceleration, and jerk are commonly restricted. As a result, productivity is reduced considerably. The aim of this work is to evaluate the potential of an axis concept with an active guide to compensate dynamic tilt errors and to avoid workpiece vibration. Therefore, an ultra-precision cross-table is presented, which combines an aerostatic gantry axis with an electromagnetically guided axis. The electromagnetic guide offers five additional degrees of freedom for fine positioning. To this end, a simulation model is developed, that comprises the multi-body dynamics of the axes as well as the feed-axis control and the magnetic actuator control. Based on the simulation, it is shown, that an electromagnetic guide as part of a cross-table axis arrangement can compensate dynamic errors, which result from inertia and disturbance forces. Moreover, the active guide mitigates the propagation of vibration from the underlying axis and test-rig to the workpiece table. Both characteristics promise to improve productivity of ultra-precision cutting.
