| 摘 要： | 瞬时切削厚度是铣削加工建模研究的重要参数之一。通过分析刀刃切削轨迹,可以得到准确的瞬时切削厚度,但需要求解复杂的超越方程。通常对切削刀刃轨迹进行不同程度的简化来求解近似的瞬时切削厚度。为得到准确的瞬时切削厚度,提出一种新的切削厚度计算模型。基于立铣刀真实切削刀刃轨迹,对近似的切削厚度模型进行补偿,得到较传统计算方法更为准确的结果,计算过程也更为简单。通过切削力试验验证,该模型可以得到更好的动态切削力预测结果。 |

| Abstract: | Instantaneous undeformed chip thickness is one of the key parameters in modeling of milling process.Through analyzing the tooth trajectory,accurate instantaneous undeformed chip thickness can be obtained by solving cumbersome transcendental equation.Traditional chip thickness models always simplify the tooth trajectory to get approximate results.A novel instantaneous undeformed chip thickness model is proposed.Based on real tooth trajectory of end milling cutter,compensation is made for the simplified model... |
