To cope with the machining requirements of high-precision beryllium copper parts,analyzing the influence of tool surface adhesive process on cutting system and machined surface is beneficial to improve the processing quality and efficiency.A two-degree-of-freedom(TDOF) cutting chatter system was established.Combining the characteristics of the workpiece material,adhesive process and interrupted cutting process,single-factor cutting test method was used to analyze the internal relationship between tool damage,cutting chatter and the machined surface.In addition,tool surface and machined surface were compared and classified through scanning electron microscope and white light interference.As a result,the difference in cutting speed and adhesive degree greatly affects the stability of the cutting process,leading to a poor surface finish.Different adhesive environment results in diverse cutting state,especially,the high adhesion rate environment is conducive to maintain the shape of cutting edge and improve the processstability.
