Abstract

According to the shape of the guide pad in the actual production, the force of the guide pad in the process of deep hole drilling is analyzed, and the results show that the force of the first guide pad is greater than that of the second guide pad. The reasonable shape of the guide pad is verified by displaying dynamic simulation and test by ABAQUS software. The results show that when the arc guide pad is used, the contact stress with the workpiece is small, the cutting formed is an ideal shape, and the dimensional accuracy, surface roughness and straightness of the parts meet the machining requirements.
