Influence of milling strategies for roundness

Very important for CNC program generation is the choice of machining strategy. This strategy has influence on the final accuracy and final quality of machined. Machining strategy is tool movement in machine space. Milling is used also for the production of curved shapes. The article compares roundness profiles of components which were manufactured by different milling finished strategies. Used strategies were Constant Z with continuous spiral, Optimized constant Z with continuous spiral and Radial. Roundness was measured on the outer cylinder (two positions) and cone surface. Article presented not only the value of roundness but also graphically shows some roundness profiles. Accuracy of parts was measured by 3D optical measuring system GOM ATOS I 350
