Selecting the appropriate machining process for CNC parts is a complex process involving multiple factors, including the design requirements of the part, material properties, machining accuracy, production efficiency and cost control. The following outlines a systematic method for analysis and selection.

机加工工艺是现代制造业的核心组成部分，是指通过机械设备对金属或其他工程材料进行切削、成形和精加工，以获得符合设计要求的零件尺寸、形状和表面质量的加工方法。

冷却至原始温度后，整个接头区焊缝及近缝区的拉应力区与母材在压应力区数值达到平衡，这就产生了结构本身的焊接残余应力。 2）焊接热输入的影响：一般情况下，热输入大时

钣金工程图管制内容详解1 确保图纸能全面反映产品结构，包括各视角视图、局部视图及剖视图。2 明确标注产品关键加工信息，如名称、客户图号、版次、材质和料厚等。

The specifications for sheet metal engineering drawings cover product structure, processing information, special structures, hardware components and technical requirements. Drawing requirements include internal bores, burr direction and the dimensioning of hardware components. The reference drawings for hardware components and formed parts specify the dimensioning methods for various components and the requirements for sectional views.
