Aluminum alloy material is light and widely used to reduce the weight of the construction element

especially in fields such as aerospace. More and more parts choose grinding as the final processing method

and the demand for efficient grinding is increasing. However

due to the good plasticity of aluminum alloy

its grinding performance is poor. The grindability of different kinds of aluminum alloys is quite different

but there are some common problems

such as the deformation of workpiece caused by the grinding force

the plastic deformation in the grinding process and the poor surface quality of the workpiece caused by the blockage of the grinding wheel by the debris. Especially for surface grinding and polishing

both of surface shape accuracy and surface roughness are necessary to control

which bring new challenges to processing technology. Scholars improve the surface quality of workpiece by selecting reasonable grinding tools

optimizing grinding parameters or using grinding fluid. Ultrasonic vibration assisted grinding and other methods are also used to improve the surface grinding quality of aluminum alloy. However

how to control the plastic deformation in aluminum alloy grinding

solve the problem of tool blockage

and achieve efficient and precise grinding of free surface remains to be further studied.
