A surface finish specification needs to connect the part’s function to a measurable result. “Black finish” may describe the appearance, but it does not define corrosion protection, electrical behavior, 涂层厚度, or the condition of a precision bore. Also distinguish surface texture from surface treatment. A roughness requirement describes a surface characteristic; anodizing, plating, passivation, and painting describe processing choices. …
A prototype can confirm that a design fits and performs in a particular test. Moving that part into repeat production requires a broader agreement: which revision will be made, which process will be used, how results will be checked, and what the customer will accept. Before increasing the order quantity, turn the lessons from prototyping into a controlled production package. …
一个有用的CNC材料选择从零件的用途开始. 一个用于固定对齐的支架, 一个暴露在清洁化学品中的轴, 以及一个滑动导向每个都会产生不同的优先考虑因素. 在比较材料价格之前,先确定这些优先事项. 目的是选择符合设计要求并且可以制造的特定等级和状态, …
