當(dāng)時(shí)間、工具、零件復(fù)雜度或材料厚度等不是很適合采用傳統(tǒng)工藝的時(shí)候，采用光蝕刻工藝往往很有用。該工藝在傳統(tǒng)上用于在單個(gè)工具上“排布”不同部件，對(duì)于開(kāi)發(fā)中有多個(gè)（具有相同合金和規(guī)格的）零件的情況很有用，或者對(duì)于待試結(jié)構(gòu)具有大量重復(fù)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(lái)加工這個(gè)零件即做一個(gè)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(guò)來(lái)夾持一中間物來(lái)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.
