Application On Technology Of CAD/CAM For The Design And Manufacturing Of Ball End Cutter

In this dissertation, application on technology of CAD/CAM for the design and manufacturing of ball end cutter is studied. The CAD/CAM integrated system of high- precision NC cutter is developed, which has been applied on the design and manufacturing of ball end cutter. The main contents of the dissertation are as following:1. The theory and method of rapid design are adopted, such as parametric modeling based on feature and dynamic simulation of processing course, the overall frame of the high- precision NC cutter CAD/CAM integrated system is built, the 3D design model of product, database and the design knowledge-base are built by using the large-scale commercial CAD software - Pro/Engineer platform.2. The 3D structure model of NC cutter is optimized analysed on the basis of 3D model, the relation between the performance of the cutter and design parameter is appraised rapidly. the best cutter geometry parameter is selected for improving the cutting performance.3. NC procedure is produced from the craft file by using CAM software, NC simulation of processing course is adopted for checking the validity of NC procedure, the NC cutter dynamic simulation of processing course is finished on the computer.4. The NC lathe is drived by computer directly,then the complicated NC cutter is rapid manufactured after receiving correct NC procedure5. The relevant special-purpose parametric module which suits enterprise's demand are added on the basis of NC processing software existed, such as the module of round profile and groove, the friendly human-computer interaction interface is offered, the development of processing special module of characteristic structure of the NC cutter is finished, the rapid manufacturing of current cutter is realized.
