【摘要】 对用无瞬心包络法加工异形螺杆时金属切除率（MRR）的算法进行了研究，提出了一种计算金属切除率的有效方法，为应用准适应控制方法对螺杆铣床进行进一步控制，以提高表面加工质量、减少振动噪声、提高加工效率奠定了基础．更多还原

【Abstract】 This paper discusses the approach to calculate the metal removal rate in machining screw with non-instant center enveloped method. Thus it provides a basis for the further quasi-control of the milling machine in order to improve the surface quality, reduce the machine vibration and noise pollution.更多还原
