Path Optimization Of High-speed Milling Of Thin-walled Workpiece And Tooling Design

High-speed processing in possess of small cutting force, low cutting thermaldeformation, high cutting speed, the high material removal rate of unit time, highprecision machining and so on, has obvious advantages compared to other processingmethods in cutting thin-wall components with low stiffness. Based on a research projectand the High-Speed processing theory, the close narrow bands (shaped hole) processingis studied in this paper used the theoretical analysis, computer simulations combined withexperiments. The choice of High-speed milling cutter, the processing path optimizationand special fixture design are researched in detail.This paper analyzes the characteristics of the structural components and processfeature. Based on the processing characteristics and high-speed machine cutting tool, therelevant tools are chosen taking into account cut-tool market factor. Discuss the cutterpath request of High-Speed milling and the main cutter path modes of the rough,finishing processing. Relying on UG4.0 and using the selected tools, simulate the roughand finishing process of the single hole. By analyzing the relevant principle andcalculation, study the problem of the cutter path optimization. The "nearest" algorithm ofTSP is the better method in more groove processing path planning of thin-walledcomponents, Take over the universal fixture mode of the thin-wall components and raisethe request of the thin-wall components fixture. According to the shape of the component,make the program of the positioning and clamping, use the ANSYS to work out thebiggest value deformation of the component, if the biggest value deformation does notexceed the allowed value and verify the accuracy of the fixture program, then design aspecial fixture.The experiment results have achieved the expected target, obtain the better qualityprocess, these show that the theoretical analysis and simulation results are correct, andthe program of fixture design is feasible. The results of the work done are the foundationof the future of the experiments and research work, also worth consideration to the actualprocessing.
