Abstract

Ram is one of the key component of high-end CNC machine tools, which casting residual stress will affect its machining accuracy, quality and performance of machine seriously. This paperutilizing blind hole method to measure residual stress of ram cast-ing,the results show that: the screw mounting face of ram castings is primarily compressive stress, the headstock mounting surface is mainly tensile stress, which tensile and compressive stresses coexist in other test surface. It can concluded that the headstock mounting surface residual stress is thet main reason for bending ram produce.The residual stress of screw mounting surface and spindle box installation site is the main reason for bending of ram. The spindle bearing installation position of Ram is the stress concentration area and the maximum stress value reached 193.2MPa, which is produce deformation or cracking easily. Through obtain the residual stress and its distribution can provide a reference for the design and optimization of the ram structure by testing and analysis.
