Abstract


Aiming at the problems that the simulation accuracy which is reduced due to the simplification of the model, a three-dimensional simulation method based on solid modeling is being proposed. By analyzing the motion relationship and positional relationship between the caries knife and the workpiece, the coordinate system of the caries machining was established. With the MATLAB software, the cutting edge model and the blade sweeping surface model of the boring cutter are sequentially established. Boolean operation is performed on the blade swept surface formed by the tooth cutter teeth with time t and the workpiece tooth geometry as well as the undeformed three-dimensional chip geometry model and the instantaneous cogging geometry model are obtained at different times. Through the compare between gear end face simulation tooth profile and the theoretical inner arc tooth profile, we verified the accuracy and rationality of the proposed method.
