To　select　appropriate　cutting　parameters　and　define　the　depth　in　residual　stress　measurement　by　stripping　layer　method,　machining　residual　stress　distribution　is　studied　under　various　cutting　parameters　by　X-ray　method.　And　the　effects　of　cutting　parameters　such　as　cutting　speed,　feed　rate　and　cutting　depth　on　machining　residual　stress　were　analyzed.　The　experiment　results　show　that　cutting　parameters　affect　the　distribution　of　machining　residual　stress　at　a　certain　extent.　And　every　parameter　shows　different　effect　on　stress.　Cutting　depth　mainly　affects　the　distribution　depth　of　residual　stress.　With　cutting　depth　increasing,　the　latter　increases.　When　cutting　depth　is　separately　0.25　mm　and　0.75　mm,　the　distribution　depth　of　residual　stress　becomes　0.2　mm　and　0.8　mm　respectively.　The　feed　rate　and　speed　affect　the　surface　residual　stress　largely.　And　the　surface　tensile　residual　stress　increases　linearly　with　the　increasing　of　the　feed　rate　and　speed.
