Semi Finish Machining Cutter Location Algorithm of Variable Axis Plunge Milling for Ruled-Surface Impeller
According to the problem of uneven allowance left by rough machining of impeller runner with 3-axis machining meth-od,a tool center point and cutter-axis vector of impeller runner variable axis plunge semi finish machining algorithm based on cutter radius offsetting along the normal direction of the surface is proposed.The axial position of cutter feeding and cutter lifting is confirmed by a existing iterative algorithm of tool center point and safety height point.The cutter position obtained can remove the uneven allowance around the blade left by rough machining of impeller runner with 3-axis machining method.The cutter lo-cation algorithm is verified by cutting experiment of semi finish machining with variable axis plunge milling method after linear axes high-speed milling and fixed axis plunge milling,and uniform allowance is left for subsequent finish milling which can make sure it going smoothly.
