針對鋁合金板生產(chǎn)加工中變形的難題，依據(jù)原材料樣子、加工的剩余量、生產(chǎn)加工方式的不一樣，變形的難題會不一樣。要想處理這個問題，就須尋找造成變形的來源于。大概有三種：內(nèi)用勁、溫度、內(nèi)應力與溫度相互結(jié)果。
In view of the problem of deformation in the production and processing of aluminum alloy plate, the problem of deformation will be different according to the appearance of raw materials, processing surplus and production and processing methods. To deal with this problem, it is necessary to find the source of deformation. There are three kinds: internal force, temperature, internal stress and temperature.
鋁合金型材工件切削變形的緣故：
The reason of cutting deformation of aluminum alloy profile workpiece is as follows:
鋁合金型材零件變形的緣故許多，與材料、零件樣子、加工工藝標準、切削油的特性等都是有關(guān)聯(lián)。關(guān)鍵有下列好多個層面：毛胚內(nèi)應力造成的變形，切削力、切削熱造成的變形，夾持力造成的變形。
There are many reasons for the deformation of aluminum alloy profile parts, which are related to the material, part appearance, processing technology standard and the characteristics of cutting oil. The key points are as follows: deformation caused by internal stress of hair embryo, deformation caused by cutting force and cutting heat, deformation caused by clamping force.

降低工件變形的加工工藝對策：
The processing countermeasures to reduce the deformation of workpiece are as follows
1、減少毛胚的內(nèi)應力
1. Reduce the internal stress of hair embryo
選用時效性及其震動解決或事先加工工藝均可一部分清 除毛胚的內(nèi)應力，容量大的毛胚工件故變形也大。若事先除掉毛胚的不必要一部分變小各一部分的容量，不但能夠降低之后工藝流程的變形，并且置放一段時間，還能夠釋放出來一部分內(nèi)應力。
The internal stress can be partly removed by using aging and vibration solution or pre-processing technology, and the deformation of the workpiece with large capacity is also large. If the unnecessary part of the hair embryo is removed in advance and the capacity of each part is reduced, not only the deformation of the later process can be reduced, but also the internal stress can be released after a period of time.
2、有用挑選刀 具幾何圖形主要參數(shù)
2. Main parameters of useful tool geometry
前角：在維持刃口抗壓強度的標準下前角適度挑選大一些，一方面能夠打磨銳利的刀口，此外能夠降低切削變形使銑面圓 滿，從而減少切削力和切削溫度。
Rake angle: under the standard of maintaining the compressive strength of the cutting edge, the rake angle should be appropriately larger. On the one hand, it can grind the sharp edge, and in addition, it can reduce the cutting deformation to make the milling surface complete, thus reducing the cutting force and cutting temperature.
后角：后角尺寸對后刃口損壞及工藝性能有立即的危害。粗銑時因為切削速度大、切削負載重、熱值大，規(guī)定刀 具熱管散熱標準好，因而后角應挑選小一些。精銑時規(guī)定刀口銳利，后刃口與表層的磨擦減少延展性變形，因而后角應挑選大一些。
Back angle: the size of back angle has immediate harm to the damage of back edge and process performance. In rough milling, because of the high cutting speed, heavy cutting load and high calorific value, it is required that the heat dissipation standard of tool heat pipe is good, so the back angle should be selected smaller. In finish milling, the blade should be sharp, and the friction between the back edge and the surface can reduce the ductility deformation, so the back angle should be larger.
螺旋角：為使切削穩(wěn)定減少切削力，螺旋角應盡量挑選大一些。
Helix angle: in order to make the cutting stable and reduce the cutting force, the helix angle should be larger as far as possible.
主傾角：適度減少主傾角能夠改進熱管散熱標準，使均值溫度降低。
Main inclination angle: reducing the main inclination angle can improve the heat dissipation standard of heat pipe and reduce the average temperature.
3、改進刀 具構(gòu)造
3. Improve the tool structure
降低車刀齒數(shù)增加容屑室內(nèi)空間。因為鋁合金材料塑性變形很大切削變形很大，須很大的容屑室內(nèi)空間，因而容屑槽底半經(jīng)應當很大、車刀齒數(shù)偏少為好。
Reduce the number of turning tool teeth and increase the space of chip chamber. Because the plastic deformation of aluminum alloy material is very large, the cutting deformation is very large, and a large space for chip holding room is needed. Therefore, it is better to have a large half diameter at the bottom of chip holding groove and a small number of turning tool teeth.
