Abstract
We present a new application of variational grid generation techniques to optimize the tool-path of an industrial milling robot. Our approach is based on a global approximation 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. The proposed technique allows to generate a tool-path for workpieces with complex geometries comprising 'islands' and/or boundaries with sharp edges requiring a combined 'spiral-zigzag' pattern. Finally, our proposed technique provides a significant increase in the accuracy of milling.
