Design And Machining Process Of Crank Arm Using CATIA CAD/CAM

Abstract

This project is to familiarize with the aerospace manufacturing that involved the use of CATIA CAD/CAM software. Each technology of machining must be supported by selection of the relevant geometry of cutting tools and cutting materials. The technological system CNC machine tool –progressive cutting tool– work piece – fixture must ensure sufficient stiffness, which has a direct influence on the quality of the surface finish of the final product. This technological process is important to enter the process of manufacturing of various precision engineering components of complex shape designed for the needs of automotive and aerospace industries. All simulations of cutting experiments show that the proposed clear-up tool path works well in the real cutting process and can improve the machining efficiency of the machining process. At the same time, the manufacturing must have the advanced process equipment and method due to the requirements of the design performance and machining efficiency. The objective of this project is to illustrate the design of the crank arm and to show the machining process of the crank arm. This can be obtained by using CATIA CAD/CAM software. The important part is to choose the right tool and machining operation for every stage to get end product (crank arm).
