摘要：
A new precision hard cutting forces model is developed based on unit cutting model, the transformation between unit and free cutting is promoted. As the characteristics of precision cutting are concerned, the cutting area and the cutting forces generated by the end cutting edge are calculated based on the actual cutting condition in the new cutting force model, the shear angle is predicted by energy approach combined with chip-flow angle and constitutive equation. The predicted results agree well with the experimental data, and the error is low that its high precision could meet the demands of precision hard cutting force prediction.
