Ling Ping，Cheng Xuesen，Chen Wei

Abstract:The article describes the turning characteristics of deep cavity thinwalled slot of 155PH stainless steel from materials and structure，and summarizes the factors that affect the machining accuracy in the actual turning process.The methods to reduce the deformation and vibration phenomena in cutting process are studied based on fixture，tool material and parameters，cutting allowances and process flow etc，and finally a set of fixture and tool are designed and a set of processing solutions are concluded.The actual production shows that this solution can effectively ensure the thin size of the deep cavity thinwalled slot and the surface quality of the slot，and can improve the clamping and processing efficiency.
