Dynamic mechanical thermal properties of frozen dough sheet;

For improving the quality of Chinese tradition frozen flour food,providing processing informa- tion for frozen flour food industry,standard wheat flour in market was selected as the material,second re- gress correctitude was performed with force(YF)and tractility(YTr)as target,two second order quadratic equations for frozen dough sheet processing were built.

Based on economical and practical thoughts,a special machining method of the blade surfaces is presented in the paper,and some relative contents about it are simply introduced,such as its NC machining process method,the structure of the machine tool,work pieces' installation and the fixture,machining process and establishment and process of the blade surfaces' mathematical model.

This paper summarizes the present inspecting methods and the developing trend of blade surfaces inspection,and introduces a better device-the Laser-scanning Machine System.

The blades are key parts to the turbine、the aeronautic engine、the ship’s thruster and others equipments,its quality will directly influence the steamy turbine’s working,but the blade surfaces’quality will directly influence the blades’quality .

The paper introduces the construction features of undevelopable ruled surface integral impeller and two 5-Axis numerical control mill machining methods of vane shape which are "line contact" (flank milling) and "point contact".
