| The cutter CAD is a modern tooling layout certainty development trend in company with the development of computer technology. When designer uses conventional handwork design procedures in design wheel cutter, accompany with lager amount of calculation, more complexity computational process, lower efficiency, and higher cost. The recount work take the time hardly and easy made a mistake when the Design result insatiability require;Then still show difficulty to require the dentiform relevant information of cutter practice or(and) require cutter shape of tooth acording to particularity workpiece shape of tooth. Therefore, introduce the CAD technology into wheel cutter Design, for increased design efficiency, shorten design cycle, ensure Design reliability of the result, if follows that enhance gear process level be of far reaching importance. In this paper, as a sort of common wheel cutter with modification coefficient for example , a cutter CAD system of gross structure frame and mathematical model had been established; then trace and research the functional module. Then a suit of CAD software base on vb had been developed to solve the deficiency of common wheel cutter with modification coefficient design procedures.The content these paper concrete research is:â‘ Analysis the influence to slotting cutter structural design, gear machining influence as adoption of modification coefficient whether in reason and the adoption's restrictive condition; at this foundation the range of choice and index of quality of slotting cutter modification coefficient was presented.â‘¡Have analyzed the structural features, worn condition in gear cutting process and the selective principles of cutter edge geometry angular,then presented the method of disposition slotting of cutter dentiform as well as the calculation and check step of parametric figure of tooling layout.At this foundation, a sort of slotting cutter modification coefficient selective mathematical model was established and a sort of algorithm of slotting cutter CAD had been researched.â‘¢At this foundation, the gross structure frame of modification coefficient slotting cutter CAD system and detailed analyses and Design concerned functional module was studied.â‘£A suit of possess tridimensional formative modification coefficient slotting cutter aided design system that could best realize programming whole function base on VB language and solidworks software had been developed. |
