The processing of forming deep hole in sheet is a kind of process using friction heat between drilling tool and workpiece to make workpiece in plastic deformation to machine hole. The process is a kind of green mechanical processing without chip. Studying green processing process in mechanical is becoming a development direction. In this paper, simulated analysis about the influence of processing parameters on the friction heat and the shape of forming hole, and researched on the temperature area of warm forming to machine hole, and then studied on quality of the hole in different temperature area in order to determine the appropriate warm extrusion temperature; Finally contrasted analysis the size of the hole of different location of test and simulation. The research results show that the simulation results agree well with the actual test results, and the warm extrusion is useful to form hole under the condition of a certain thickness.
