The Reverse Modeling Software About A Profile Cutter’s Development And Application

The forming part of spaceflight components general need to use the molding cutterfor NC machining. Through the UG NX8.0preparation the NC program, need to createa custom the molding cutter. At present, To create custom cutter must through themanual input parameters of each cutter section line, then the CAM module candistinguish, and as a cutter for processing. If the more the number of the cutter sectionline, more complicated that create the cutter by manual methods, more error. In this way,it will greatly affect reliability, rapidity, accuracy, validity of the NC program, greatlyreduce the production efficiency and production quality of the product.In order to solve the above problems, design a reverse modeling software about aprofile cutter can automatic extraction the data of section line that the shape of cuttingtool in the modeling module, instead of manual query and input the data of section lineof cutting tool, save a lot of time to create the cutting tool, the NC program is fastly andaccuracy, shorten the processing cycle, greatly improve the efficiency of NC machining.This thesis mainly studies that develop the software about the requirements of reversemolding on the molding cutter in the UG NX8the Secondary development platform, thesoftware can automatically obtain the parameters in the modeling process and gather theprocessing module, can make a summary for profile cutter with different specifications,and leading in the NX cutter library, NC programmers can reconstruction andmodification the parameter information of the molding cutter at any time,Can quicklytransfer from the NX tool library in the NC machining simulation.The reverse modeling software about a profile cutter through functional testing,modeling parameters well be smoothly read, parameters of the cutter generated by thesoftware is correctly, from the cutter library transfer cutting tool is regularly. Using thesoftware not only convenient for NC program, but also to ensure the correctness of NCprogram, reduce the difficulty that the preparation of the NC program NC program.Therefore, the software meet the demand that NC program for the factory.
