Abstract: Based on the function of Chooks in MasterCAM, the section of a oval gear is generated. An oval gear 3D Model is established using the section in UG, then a pair of assembling oval gear in UG is imported into ADAMS, motion simulation results are validated and compared with the theoretical value. The results indicate that the profile conversion method can meet the design requirements in certain conditions of transmission accuracy, and effect of eccentricity to the transmission of oval gears is summarized.

Abstract: Finite element model of the matching of lengthened shrink-fit holder (LSFH) and cutting tool is established and a milling force model is developed to predict the transient milling force exactly using back propagation neural network (BPNN). Subsequently, the transient dynamic characteristic of matching of LSFH and cutting tool is analyzed and the simulation result is obtained. Finally, the simulation result is verified with practical measurement and the results fit very well. The studies are important to optimum design and select the lengthened shrink-fit holder in high speed milling.
