Paper Title:
A Two-Dimensional Fast Tool Servo Used for Real Time Error Compensation in Taper Turning
  Abstract

In this paper, a two-dimensional (2D) fast tool servo driven by piezoelectric actuators for real time error compensation in taper turning is described. A 2D tool post is made with a new structure with three leaf springs for each axis and its mounting platform positions at a corner, which makes it convenient for mounting the cutter. A control technique, “Forecasting Compensatory Control” (FCC), is implemented to perform an on-line prediction of the machining errors encountered. The on-line cutting experimental results have verified that an improvement of about 40% was achieved for roundness error of the workpiece in the taper turning operation by using the developed control algorithm.
