其时间、工具、零件重漂后或质料厚度等不是很适合接纳古板工艺的时间，，，，，，接纳光蚀刻工艺往往很有用。。。。该工艺在古板上用于在单个工具上“排布”差别部件，，，，，，关于开发中有多个（具有相同合金和规格的）零件的情形很有用，，，，，，或者关于待试结构具有大宗重复的情形也很有用。。。。大连细密零部件加工一样平常是不可卡抓直接去夹持：这样我们就必需思量用一种间接夹持的要领来加工这个零件即做一个工装，，，，，，工装的做法围绕着镌汰x轴向力的原则下接纳z向牢靠的要领，，，，，，可以通过来夹持一中心物来把所要加工的零件借助于配合和压板使之z向牢靠。。。。

When time, tools, part complexity or material thickness are not suitable for conventional processes, photoetching technology is often very useful. Traditionally, this process is used to arrange different components on a single tool. It is useful for developing multiple parts with the same alloy and specifications, or for structures with numerous repetitions to be tested. In Dalian precision parts machining, direct clamping is generally not applicable. Therefore, an indirect clamping method must be considered, namely designing a fixture. The fixture is designed to fix the part in the Z-direction while minimizing axial force in the X-direction. By clamping an intermediate piece, the workpiece is fixed in the Z-direction through fitting and pressure plates.
