當時間、工具、零件復雜度或材料厚度等不是很適合采用傳統工藝的時候，采用光蝕刻工藝往往很有用。該工藝在傳統上用于在單個工具上“排布”不同部件，對于開發中有多個（具有相同合金和規格的）零件的情況很有用，或者對于待試結構具有大量重復的情況也很有用。大連精密零部件加工一般是不能卡抓直接去夾持：這樣我們就必須考慮用一種間接夾持的方法來加工這個零件即做一個工裝，工裝的做法圍繞著減少x軸向力的原則下采用z向固定的方法，可以通過來夾持一中間物來把所要加工的零件借助于配合和壓板使之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.
