Process planning and NC-code generation in manufacturing of press dies for production of car bodies

摘要: This paper presents a process planning system that generates plans and NC codes for machining of press dies, which are used in manufacturing the body panels cars. consists three modules: macro-process major parts dies; an operation free-form surfaces; NC-code post-processor analyses modifies codes. Fifteen part-families (PFs), along with their standard plans, defined planning. A is set unit operations, can be completed without changing set-ups. Details, such as cutting tools, conditions, tool paths decided upon during stage. After generating cutter location (CL) files, using commercial CAM systems, selects tools lengths to generate At final stage planning, code pos...
