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般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 very suitable for traditional processes, using photolithography technology is often very useful. This process is traditionally used to "arrange" different components on a single tool, which is useful for situations where there are multiple parts (with the same alloy and specifications) in development, or for situations where there is a large amount of repetition in the test structure. Dalian precision parts processing generally cannot be directly clamped by grabbing: in this case, we must consider using an indirect clamping method to process this part, which is to make a fixture. The fixture method is based on the principle of reducing the x-axis force and adopts the z-direction fixing method. By clamping an intermediate object, the part to be processed can be fixed in the z-direction with the help of fitting and pressure plate.
