Abstract

Position-velocity-time (PVT) is a motion mode supported by many modern motion controllers. It describes the motion with piecewise cubic polynomials, which results in smoother motion profiles. However, there is no PVT-based motion scheduler available for implementing dwell time in computer controlled optical surfacing (CCOS) applications. To fill this gap, we present a novel PVT-based motion scheduler constrained by the machine dynamics for CCOS. The principle of the proposed method is explained, followed by the verification of smoothness and accuracy with different type of tool paths. Finally, a PVT-based surface generation simulator is demonstrated.
