Abstract

Today, any CAM software offers some different tool trajectories strategies for milling free form geometries. In any finishing milling operation the most important objective is the surface quality. However, the CAM users must have the know-how to choose the tool trajectories according to geometry complexity, cutting tool geometry and its contact on the machined surface. The quality of the surface and machining time is influenced also by tool trajectories. Research results presented in this paper are focused on determination of a correction factor for cutting parameters based on tool trajectories type. To validate experimental correction factor, optimum feed rates are calculated for each type of trajectories based on surface quality and machining time analysis for inclined surfaces. The finishing procedures are made with a ball end milling tool.
