In: 9th CIRP Conference on High Performance Cutting. on-line, 2021-05-24/2021-05-26. Amsterdam: Elsevier B.V., 2021. p. 69-72. ISSN 2212-8271. DOI 10.1016/j.procir.2021.03.124.
This paper deals with a method to optimize tool axis orientations in multi-axis milling toolpaths. The method is based on calculation of the actual cutting diameter and the cutting speed during the toolpath. Subsequently, the NC code is processed by the interpolator with a machine tool kinematic model. The result is a visualization of the actual cutting speed and the real feed-rate on the toolpath. Based on these results, the vectors used to orient the tool axis along the toolpath can be effectively set up in several iterations. The toolpath are optimized to achieve a more constant cutting speedwhich lead to an improvement in surface quality and increase in productivity.
