其时间、工具、零件庞漂后或质料厚度等不是很适合接纳古板工艺的时候，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）零件的情况很有用，或者关于待试结构具有大宗重复的情况也很有用。大连精密零部件加工一般是不可卡抓直接去夹持：这样我们就必须考虑用一种间接夹持的要领来加工这个零件即做一个工装，工装的做法围绕着减少x轴向力的原则下接纳z向牢固的要领，可以通过来夹持一中间物来把所要加工的零件借助于配合和压板使之z向牢固。

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.
