Form Cutter CAD/CAM Based on Manufacture Engineer

摘要

Traditional form milling cutter for involute gears with approximate involute edge causes large error of tooth. The manufacture process of cutter, profile modeling, also causes low precision of edge form and short life of the cutter. Form milling cutter CAD/CAM based on Manufacture Engineer improves the precision of cutter edge curve and manufactured gears, and prolong the life of cutter. In the milling cutter CAD/CAM, the ME software was used to establish 3-D modeling of cutter, process simulation of cutter manufacturing and program automatically for CNC cutter grinder. The methods of edge curve design, tool-path calculation and manufacture processing of cutter on CNC cutter grinder were discussed. Machining examination indicates that precision of manufactured gear tooth increases by 2 ～ 3 levels by eliminating the error of cutter edge curve and profile modeling system, and the life of cutter increases by 2 ～ 4 times.
