Abstract

The effects of the initial clamping force, the number of plates and the area of plates on the deformation of 2050-T84 Al-Li alloy were studied. The pressure sensor is placed between the workpiece of the press plate through the four-point clamping plate, and the change of forward pressure and cutting force is measured simultaneously. In the process of machining, the forward pressure and the cutting force change dynamically at the same time, when the initial clamping force changes, the cutting force also changes. Workpiece deformation is the result of coupling of initial clamping force and cutting force. After machining, the flatness also changes with the initial clamping force. Due to the existence of "over-cutting" phenomenon, the surface smoothness of the machining area presents the characteristics of "convex". The initial clamping force of the surface has a significant effect on the deformation of the thin plate. Increasing the number of plates slightly reduces the deformation, and increasing the area of plates can effectively reduce the deformation.
