Design of the flute grinding parameters to be produced with parallel grinding machine

The flute machining is important to produce a milling cutter. The geometric parameters (especial its rake angle, flute depth and flute width) have essential influence on the performance of the tool. Using a 6-UPS parallel machine, based on analyzing its special machining and structure features, general analysis was given for all factors which will influence of flute forming, and according to the motion relation between grinding wheel and the milling cutter, a simulation model system was established, that can optimize and quantitative design all of the parameters quickly. These parameters include the grinding wheel deflexion, the grinding wheel thickness, the grinding wheel offset position along the axes direction, and the flute depth. These parameters have been verified by experiments.
