数控加工工艺：凹圆弧多配合综合件的设计与程序编制【摘要】

This paper focuses on the CNC machining process and programming of concave arc more comprehensive coordination. The research is based on the implementation of fixture clamping using milling arcs and precision flat-jaw clamps on the FANUC Series-0i-MC. Various cutting tools such as end mills, ball end mills, high-speed steel drill bits, high-speed steel reamers, and solid carbide thread mills are used to machine the parts in order to achieve multiple fits. After reviewing relevant literature and references, the technical characteristics, geometric shapes, dimensions, and process requirements of the concave arc more comprehensive coordination parts are analyzed. The machining content and requirements are clarified, and the machining plan is determined. With the guidance and assistance of the instructor, a machining process that meets the requirements of the comprehensive part is designed, and a concise and convenient machining program is developed. The feasibility of the design is verified through simulation machining on a virtual machine tool. The key elements of this research include multiple fits, machining process design, macro programming, right-hand threads, and concave arcs. This study provides valuable insights into the CNC machining process and programming of complex parts, and demonstrates the importance of meticulous planning and execution in achieving successful machining operations.
