摘要：

提出了一种适用于球头铣刀多轴铣削加工的铣削力系数辨识方法.首先，将剪切力系数考虑为轴向位置角κ的多项式函数，推导了基于平均铣削力的铣削力系数辨识模型.然后，设计了多组刀具轴线与工件表面夹角不同的槽切铣削实验来实现铣削力系数辨识，以保证通过实验辨识得到的铣削力系数包含了球头铣刀不同姿态切削对铣削力的影响因素.最后，通过实验验证了该方法的正确性和可靠性.实验结果表明，该辨识方法相比于基于瞬时铣削力的辨识方法具有更好的抗干扰能力和更高的辨识精度，适用于球头铣刀多轴铣削加工的铣削力预测.

Abstract:

A new method for the identification of milling force coefficients is proposed for the prediction of the milling forces in multi-axis milling with ball-end cutter. Firstly， the shearing coefficients of milling forces are fitted with multiple order polynomial function of axial position angle， the identification model is derived based on average milling forces as well as the milling force model of multi-axis ball-end-cutter milling. Secondly， the experiment plan of multiple group slot milling for milling coefficient identification is presented， in which the groups are distinguished from each other by varying the angle between the cutter axis and the work piece surface in the slot milling. This experiment is used to ensure the identified coefficients contain the effect factor of different cutter postures. Finally， the proposed method is validated experimentally and the results show that the proposed method is better than that based on instantaneous milling forces in terms of anti-interference and identification precison.
