Abstract

According to the practical condition and traditional design parameters of the oblique hole drilling, the mechanical model for the oblique hole drilling is established. With the finite element analysis software, two conditions are analyzed: the bit is not completely drilled into the workpiece, and the bit is completely drilled into the workpiece. At the same time, the effect of coaxiality error on the bit life is considered, and the influence law of the drill bush radial parameters on the bit life is analyzed. Then, the pre deformation method is adopted to solve the statically indeterminate problem by using the finite element software, and the comprehensive life analysis method for the bit life under multiple conditions is presented. Compared with the production in the enterprise, the theoretical analysis is consistent with the actual situation. The analysis shows that the feed rate of the oblique hole drilling and the coaxiality error are the key factors affecting the bit life.
