1、Select the appropriate processing method：

Layered multiple processing method:

When there are multiple camultiple cavities on the aluminum alloy plate parts that need to be processed, the layered multiple processing method can be used.

That is to say,all cavities are processed at the same time, but not at one time,but at several levels layer by layer to the required size.

In this way, the intersection is uniform and the probability of deformation is small.

2、Appropriate selection of cutting parameters：

Choosing the right cutting parameters that can effectively reduce the cutting force and cutting heat in the cutting process, thereby reducing the possibility of part deformation. Among the various elements of cutting parameters, the back engagement has the  greatest impact on the cutting force. Among the various elements 

of cutting parameters, the back engagement has on the cutting force.

Secelt the aappropriate tool material and angle:

Compared with ferrous metal, the cutting force of aluminum ally is smaller in the cutting process, but it is easy to stick to the tool and form  bulit-up edge.

Therefore, the selection of appropriate tool materials and angles, such as improving the roughness requirements of the tool surface is very helpful to reduce the cutting force and cutting heat.

The cutting deformation, cutting force and cutting temperature can be reduced by reasonably selecting the parameters of the tool, such as rake angle, clearance angle, helix angle and tool cutting edge angle.

3、Improve the cutter structure：

Aluminum alloy material has large plasticity and large cutting deformation in machining , so it nedds large chip space.

It can be cut by milling cutter, the number of teeth and increase of chip space are used to improve the tool structure.

4、Heat treatment  technolohy：

The heat treatment methods to eliminate the processing stress of aluminum alloy material mainly include stress relief annealing,aging and so on. 

The methods can reduce the deformation of the aluminum alloy material in the processing process. 

5、Use cold treatment technology：

Cold treatment methods such as vibration aging and artificial cold sizing can be used to solve problem of processing deformation of aluminum alloy.

These methods have Nergy-saving, short production, low production cost and the like.

By taking the above measures, the deformation of aluminum alloy precision mechanicak parts in the processing process can be effectively 

raise the parts machining accuracy and quality.
