Abstract：This article focuses on the key technical challenges faced in the machining process of automotive throttle body castings， such as high precision requirements，complex machining features，and difficulties in clamping and alignment of raw materials. It proposes a five-axis combination processing solution. The solution systematically covers key aspects such as the selection of high-precision machining centers， the optimization of special cutting tools，the design and precision manufacturing of customized fixtures， and the comprehensive upgrade of inspection processes. Through practical application and rigorous verification， the solution has significantly improved the machining accuracy and yield rate （over 95% ）of throttlebody castings. The successful implementation of this case not only provides a highly efcient and feasible solution for the machining of automotive throttle body castings， but also provides new ideas and references for technological innovation and process optimization in related fields.
