ABSTRACT 、， 、 1， M Gear is widely used in automotive，aviation， shipbui1ding，military and other fields as 白e most widely used drive device. As the key drive components of all types ofmachin田y，也.e manufacturing processes of the ge盯 products and its quality directly affect the quality of complete machines. Therefore，也e precision of ge即 shaping machine directly affects the machining accuracy，and the transmission p町formance and noise of gears further. Machine precision design，an important st叩 in machine desi扭， is the key ωdet町mine 由e price quality and success of 由e products. The 衍aditional precision design method is prim町ilyωcalculate the precision of ev即y machine tool p盯ts in 伽e 位ansmission chain based on the given precision of machine tools terminal actuators. It is the precision desi伊 which is oriented to the manufacturing 叫uipmen邸， but it can t meet 由.e machining precision r，叫uirement of superprecision machining.η1时efore，由is pap时 explores the issues on gear shaping machine tool s precision desi部1 from the r叫uirement of 伽e gear precision and machining mechanism. Main contents and results 盯e 础 follows. 1.The ge町 precision r，叫uirement-oriented active precision design method of gear shaping machine tool is proposed. It designs ge町 shaping machine precision from the mωhanical precision requirement of gears and machining mechanism. 丁he basic idea of this me也od is to establish the mapping model according to the gear shaping machine tools motion error and the gear machining error，and 由en to establish 伽 gear mechanical precision model based on 由.e error mapping model. Finally，transform 也e requirement of 也e ge町 precision to the motion precision of 也ree CNC controlled axis according to the machining precision mode1. According ωthe principles of ∞njugating too曲， it establishes the tooth surface model of the involutes cylindrical ge盹 and the tooth model is validated. With 也e analysis of the influence factors of gear tooth surface machining error， i
