Cutting Tool CAD And Software Development About Large And Complex Components

Along with the abroad application of large and complex components in energy sources, transportation, national defense and such domains, the research on cutting tool about large and complex components is getting more and more important.Because of the complex structure of large and complex components, traditional design methods cannot work upon the development of new style cutting tools any more. Using the powerful 3D modeling function of large integrated software UG, this thesis designs 3D groove round milling inserts and vertical handle large feed milling tool with two inserts for large and complex components, and optimizes their geometry parameters.The waved-edge milling insert for large and complex components, which has complex 3D groove and unique cosine wave edges, has complex and different cut-in styles compared with flat groove insert. For researching the relationship between the cut-in style and the disrepair of the waved-edge milling insert, this thesis develops the waved-edge milling insert cut-in simulation system using UG/Open API combined with VC++, simulates the cut-in process of waved-edge milling insert to supply proof for judging cut-in style and studying cut-in disrepair.Large containers, which are used a lot in chemical industry and nuclear power plant, bring amount of difficulties in choosing cutting parameters because of its difficult-to-machine material and large size. For correctly selecting process parameters and improving the productivity of optimizing, this thesis develops process database and parameter optimizing expert system using VC++ and SQL Server, sets up databases of workpiece, machine tools, cutting tools and fluid, offers the data storage and query function, designs turning and milling sub-systems to select cutting tools and fluid and to optimize machine data aimed at different optimal aim function models.
