| Abstract: | There are various degrees of remnant stress in the heavy duty machine tools' compornents made by casting and welding.Remnant stress is apt to make these components for foundation structure to become deformed and in crackle state,eventually infect the machine tool's accuracy.In order to decrease remnant stress,this paper attempts to take feasible technological measures to reduce component's remnant stress and to increase stability of geometry accuracy in machine tools. |

| Keywords: | thermostable stress relief foundation structure component accuracy remnant stress |
