tudy on optimum processing technology of centrifugal impeller Abstract Overall centrifugal impeller is a kind of representative and modelling is more normative, typical channel plex parts, working profile involves the aerodynamics, fluid mechanics, and other disciplines. Work speed generally is 400007000 revolutions per minute, working temperature is 400700 degrees Celsius. So for centrifugal impeller machining method, precision, and has a high surface quality requirement. For its processing technology research and improvement has great practical significance. In this paper, we study a centrifugal impeller for the following: the impeller milling, milling to make use of VERTCUT simulation, locate mode of processing, cutting tools, procedures, etc, parameters optimization, reduce the quality problem, enhance leaf type processing efficiency, leaf surface roughness and surface integrity, the outline shape of impeller, small end, merging processing, small end diameter of impeller big end and small end diameter to drive the car generation of grinding mill, through the research of two aspects of mon and the numerical control turning to improve the machining efficiency, product quality, reduce machine tool production scheduling waiting time. At the same time, the impeller machining also belong to the thin wall parts, machining deformation appear easily in the process, brought great inconvenience to processing. Belongs to the difficult processing, flexible type parts. Therefore, we use a type impeller as an example, the study of optimized scheme. Key words: Profile milling Grinding burn Acid corrosion test Car for grinding Difficult to processing Easy to deformation 目 錄 摘 要 ....................................................................................................................................
