Abstract :
Active control of the metal turning process using a direct drive linear motor actuator is is investigated. A general open loop system model and closed loop control scheme is formulated for both circular and noncircular turning. A theoretical stability analysis and simulated circular cutting results for PID regulation is presented. Stability improvements were achieved while controlling tool position only despite the presence of workpiece flexibilities.
