Process characteristics of aluminum parts processing:

(1) can reduce the influence of residual stress on processing deformation. After the completion of rough machining, it is recommended to use heat treatment to remove the stress generated by the rough machining of the part to reduce the impact of stress on the quality of finishing.

(2) Improve machining accuracy and surface quality. After the separation of roughing and finishing, finishing is just a small machining allowance, machining stress, and deformation is small, which can greatly improve the quality of the parts.

(3) Improve production efficiency. Because rough machining only removes excess material, leaving enough margin for finishing, so do not consider the size and tolerance, effectively plays the performance of different models of machine tools to improve cutting efficiency.

After the aluminum parts are cut, the metal organization in the machining table will be greatly changed. In addition, the effect of cutting motion can lead to greater residual stresses. In order to reduce the deformation of the part, the residual stresses in the material need to be fully released.

1. Machining datum selection: machining datum should be consistent with the design datum, assembly datum, and measurement datum as far as possible, and the machining process should give full consideration to the stability, positioning accuracy, and clamping reliability of the parts.

2. Rough machining: As the machining dimensional accuracy and surface roughness of some aluminum alloy parts are not easy to meet the requirements of high precision, some parts with complex shapes need to be rough machined before processing and cut in combination with the characteristics of aluminum alloy materials. The heat generated in this way will lead to cutting deformation, increase the error of part size in different degrees, and even lead to deformation of the workpiece. Therefore, for the rough machining of generally flat surfaces, milling and planing are used. At the same time, coolant is added to cool the workpiece to reduce the effect of cutting heat on machining accuracy.

3. Finishing machining: In the processing, high-speed cutting will produce a large amount of cutting heat, although the debris can take away most of the heat, the blade can still produce a very high temperature, due to the low melting point of aluminum alloy, the blade is often in a semi-melting state so that the strength of the cutting point is affected by high temperature, easy to produce aluminum alloy parts in the process of forming bump defects. Therefore, in the finishing process, usually choose the cutting fluid with good cooling performance, good lubrication performance, and low viscosity. In the lubrication tool, timely take away the cutting heat, reduce the temperature of the tool and parts processing surface, and reduce the temperature deformation of the parts.

4. Reasonable choice of tools: Compared with ferrous metals, aluminum alloy materials produce relatively small cutting forces in the cutting process, you can use a larger cutting speed, but it is easy to form a chip tumor. The thermal conductivity of aluminum alloy is very high. Due to the high heat of debris and parts during the cutting process, the temperature of the cutting area is low and the durability of the tool is high, but the temperature rise of the part itself is faster and easily causes deformation. Selecting the right tool material, choosing a reasonable tool angle, and improving the surface roughness of the tool are very effective in reducing the cutting force and cutting heat.

5. The use of heat treatment and cold treatment to solve the processing deformation: heat treatment methods to eliminate the processing stress of aluminum alloy materials are: artificial timeliness, recrystallization annealing, etc. The simple structure of the parts process route is generally used: rough machining, manual just-in-time, and finishing. For the process route of parts with complex structures, generally use rough machining, artificial promptness (heat treatment), semi-finishing, artificial promptness (heat treatment), and finishing. While arranging a manual just-in-time (heat treatment) process after roughing and semi-finishing, a stable heat treatment process can be arranged after finishing the part to prevent small dimensional changes in the process of part placement, installation, and use.
