INVESTIGATION ON CUTTING TIME RATIO AND DRILLING FORCE OF VIBRATION DRILING

摘要

In this paper, by analyzing the axial cutting thickness, a concept of cutting time ratio K in vibration drilling is introduced. The new drilling force model of separate vibration drilling is presented. And the drilling force model includes cutting force and chip-evacuation force. The results of simulation and experiments prove that the model is right. The experiment results also show the effect of cutting time ratio on the drilling force.
