Interactive Haptic Refinement of a Five-Axis Finishing Cut

Abstract

This paper describes the design of a haptic system that allows the interactive modification of cutter orientation during five-axis finishing cuts with the aim of improving the surface finish quality and collision avoidance strategies. The system supports two haptic models that provide three degree of freedom (DOF) force feedback and 6DOF posture sensing. Details of five key functions of the system are given: (1) a rendering conversion that uses 3DOF (instead of five) force feedback haptic representation, (2) an efficient force feedback design that allows accurate results to be obtained from the user’s manipulation, (3) a fast collision detection scheme that achieves real-time feedback, (4) use of active haptic guidance to assist cutter-path generation, and (5) a design that supports both ball-end and flat-end tools with partial optimization.
