Analysis of machining of the workpiece clamping stability， according to common processing of the hands of the workpiece， determine the stability of the classification and identification method of calculation， application Visual C + +0 and Access2000 and other software platforms， the development of feature-based automated fixture design determine the stability of the system subsystem
all kinds of machines are widely used in manufacturing field and daily as different new kinds of macines are developed based on the application of diverse knoledge and technologies， the term machine has been given new this design is mainly for the tap-driving， the gear power transmission， the verification and basic design theory of gear wheel， the calculation methods and the selection and maintenance for each section follows the order of operation mechanism， structure calculation， strength calculation and the maintenance to give an now design methods are being improved with the development of the science technoloty and the further comprehension to however， normal design methods are still the basic for mechanical engineering the transmission design xhould meet the operation requests and gain the characteristics of compaction structure， easy manufacturing and convenient keywords: tap-driving， gear power transmission，design theory， calculation process， gear
