摘要
We present a new approach to tool-path optimization of milling robots based on a global interpolation of the required surface by a virtual surface composed from tool trajectories. The procedure combines inverse kinematics techniques and a variational gridding method endowed with constraints related to the required scallop height. We demonstrate the capability of the proposed technique to generate a tool-path for workpieces with complex geometries comprising 'islands' or boundaries with sharp edges requiring a combined spiral-zigzag pattern. Our technique provides a significant increase in the accuracy of milling. (C) 2002 Elsevier Science Ltd. All rights reserved.
