Computer-aided part program optimization of multi-component pallet residence time in a machining centre for canned cycles and cutter tool compensation

Abstract

Abstract The paper concerns the development of computer-aided techniques for the minimization of the total residence time of a multi-component pallet in a machining centre. Methodologies have been developed to take part programs for many components, segment them, automatically re-sequence them, and regenerate them. Modern control features such as canned cycles, tool length offset, and tool radius compensation have been included to make the techniques more widely applicable. It is shown that the use of the computer-aided optimization techniques reduce the non-productive tool movement by up to a factor of 27%. Representative examples are given in the paper which demonstrate the techniques and the methodologies developed.
