Analyzing Of Departure From Straightness Of Cylindrical Whirling Cutter Milling

With the scope of application of the slightness shaft parts is applied widely, its importanceis increasingly prominent in various types of machinery institutions. Usually after processing orheat treatment the slightness shaft parts there will be varying unavoidable degrees of bendingdeformation occurs, and the low processing efficiency, because of its structural characteristicsand the limit of the processing method. With the amount of demands are increasing and theslightness shaft parts requirements of precision and efficiency are made to further expanded.Thetraditional processing methods will be difficult to meet the high precision and high efficiencyrequirements. Whirlwind milling is an efficient, low consumption and high-precision machiningmethod to replace the turning processing methods of the current stage to meet market demand.The cylindrical whirling cutter milling machine this paper presented has rigid, good stabilityand high cutting efficiency.The cylindrical whirling cutter milling machine is combined the characteristics of thewhirlwind milling technology’s efficient, smoothly cutting and precision numerical. It is a kindof batch milling machine for processed the surface of the cylindrical slightness shaft parts.The slightness shaft part occupies an important position in the mechanical mechanism, and itsstraightness is an important indicator of the quality. More accurate analysis of its departurefrom straightness is the key to ensure and improve the related machinery quality of productsand the quality of products running. This paper presented to analyze the departure fromstraightness of the whirlwind milling slightness shaft parts.The movement principle and the machine structure of cylindrical whirling cuttermilling machine were analyzed and the expression of axis bending was combined. Themodel of departure from straightness error was established from the perspective ofgeometry to given, in order to get the departure from straightness correction of the beforeand after milling of slender shaft parts. The paper combined the theoretical analysis and thevarious numerical changes of the slightness shaft parts actual observation in millingmachine. Proved that the machining precision of the cylindrical whirling cutter millingmachine meets the requirements and it can be used to practical production assembly. Proved that the slightness shaft parts of the cylindrical whirling cutter milling machine is concise andeffective, and it has more extensive practical engineering significance.
