其功夫、工具、零件复杂度或资料厚度等不是很适合选取传统工艺的时辰，选取光蚀刻工艺往往很有效
。该工艺在传统上用于在单个工具上“排布”分歧部件，对于开发中有多个（拥有一样合金和规格的）零件的情况很有效，或者对于待试结构拥有大量沉复的情况也很有效
。大连精密零部件加工通常是不能卡抓直接去夹持：这样我们就必须思考用一种间接夹持的步骤来加工这个零件即做一个工装，工装的做法萦绕着削减x轴向力的准则下选取z向固定的步骤，能够通过来夹持一中央物来把所要加工的零件借助于共同和压板使之z向固定
。

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.
