現(xiàn)代人使用的特殊鋁合金外殼加工方法，多是通過(guò)路線膠粘砂、激光器激光切割、鉆孔、銑削、鋸齒等方法實(shí)現(xiàn)的。這些工藝方法，首先要保證特殊鋁合金外殼的材料和特性，其次對(duì)于激光切割、鉆孔和銑切等工藝方法，有一些共同的要點(diǎn)，是實(shí)現(xiàn)特殊鋁合金外殼加工的基礎(chǔ)。

　　激光切割是特殊鋁合金外殼加工中應(yīng)用較為廣泛的一種方式，其基本原理是能量集中的激光束照射到工件表面，使得工件表面材料的溫度迅速升高至沸點(diǎn)，形成一條切縫。

　　激光切割的關(guān)鍵是保證激光光斑的大小和形狀，能夠達(dá)到切割要求。因此，對(duì)于特殊鋁合金外殼材料上的激光切割，首先要保證集成激光器的輸出功率具備足夠的能量，使激光光斑具備足夠的熱能；其次，應(yīng)用的激光集成器的脈沖寬度應(yīng)選擇合理，使得激光脈沖能夠在特定的材料上產(chǎn)生一定的效果；再次，對(duì)于激光光斑的形狀，應(yīng)不斷優(yōu)化激光切割方式，以期獲得較好的切割效果。

　　鉆孔是使用鉆頭切割工件表面上的一個(gè)孔，為了使鉆孔工藝達(dá)到要求，首先要確定好鉆孔位置，其次要選擇合適的鉆頭，最后要適當(dāng)調(diào)節(jié)鉆孔的速度。

　　銑削是一種在車床、銑床或其他相應(yīng)的機(jī)床上進(jìn)行的工藝方法，通常使用的工具是刀片，而銑削的主要目的是使特殊鋁合金外殼材料表面形成一定的弧度或曲線。

　　銑削工藝首先要控制刀具的運(yùn)動(dòng)速度，使刀具的運(yùn)動(dòng)速度與材料的硬度相適應(yīng)；其次，刀具的刃形也會(huì)影響銑削的效果，通常使用的刀具有長(zhǎng)刃、短刃、直齒、斜齒、刃口夾持等；再次，銑削工藝中也會(huì)使用到一些輔助工具，如銑刀架、銑夾、潤(rùn)滑油等。

　　鋸齒是特殊鋁合金外殼加工中使用較為廣泛的工藝方法，主要目的是使特殊鋁合金外殼表面形成一定的鋸齒狀。鋸齒工藝首先要確定好鋸齒的類型，其次要確定好鋸齒的形狀，最后要適當(dāng)調(diào)整鋸齒的速度。

　　The processing methods of special aluminum alloy shell used by modern people are mostly realized by adhesive sand, laser cutter, drilling, milling, sawing and other methods. These process methods should first ensure the material and characteristics of special aluminum alloy shell, and secondly, there are some common points for laser cutting, drilling and milling. The processing of special aluminum alloy shell.

　　Laser cutting is a widely used way in the processing of special aluminum alloy shell, and its principle is that the energy focused laser beam irradiates the surface of the workpiece, so that the temperature of the workpiece material surface rises quickly to the boiling point, forming a cutting seam.

　　The key to laser cutting is to ensure the size and shape of the laser spot, so as to meet the requirements of cutting. Therefore, for the laser cutting of special aluminum alloy shell materials, first of all, it is necessary to ensure that the output power of the integrated laser has enough energy to make the laser spot have enough heat energy; secondly, the pulse width of the integrated laser used should be reasonably selected to make sure The laser pulse can produce certain effects on specific materials; thirdly, for the shape of the laser spot, the laser cutting method should be continuously optimized in order to obtain better cutting effect.

　　Drilling is to use a drill bit to cut a hole in the surface of the workpiece. In order to meet the requirements of drilling process, first of all, we should determine the position of drilling, secondly, we should choose the appropriate drill bit, and finally we should adjust the drilling speed properly.

　　Milling is a process method performed on lathe, milling machine or other corresponding machine tools, which is usually performed by using tool blades. The main purpose of milling is to form a certain radius or curve on the surface of special aluminum alloy shell material.

　　The milling process should firstly control the speed movement of the tool so that the speed of tool movement is consistent with the hardness of material; secondly, the blade shape of the tool will also affect the milling effect, and the commonly used tools include long blade, short blade, straight tooth, oblique tooth, blade holders and so on; finally, Milling process will also use some auxiliary tools, such as milling plates, clamps, lubricants, etc.

　　Sawtooth is a technology used more frequently in the processing of special aluminum alloy shell, and the main purpose is to form a certain sawtooth shape on the surface of special aluminum alloy shell. The sawtooth process should first determine the type of sawtooth, secondly determine the shape of sawtooth, and finally adjust the speed of sawtooth properly.
