这两部分的文件解决了与无心磨削相关的凸角行为。第一部分建立了一个系统模型（波瓣环）的波瓣分析和发展的波瓣稳定性分析的方法，和第二部分研究波瓣特性，并提出补救措施，波瓣抑制。波瓣环表明波瓣行为是运动学性质的，由几何倒圆机制之间的相互作用引起。和再生切削机构。随后发展了一种双积分方法来估计波瓣稳定性。有人发现，波瓣是固有的不稳定，和波瓣环的特征根被限制在其各自的根邻域中的u平面。这导致：（1）一种使用增长率边界进行波瓣稳定性估计的方法，以及（2）一种使用泰勒级数逼近求解特征根的有效方法。生长速率边界和特征根分布的存在为控制无心磨削中的凸角提供了一种有效的工具。
This two-part paper addresses the lobing behavior associated with centerless grinding. Part I establishes a system model (the lobing loop) for lobing analysis and develops methodologies for lobing stability analysis, and Part II investigates lobing characteristics and proposes remedies for lobing suppression. The lobing loop shows that lobing behavior is of kinematic nature, caused by the interaction between the geometric rounding mechanism. and regenerative cutting mechanism. A bidiagrammatical method is subsequently developed for lobing stability estimation. It was found that lobing is inherently unstable, and the characteristic roots of the lobing loop are limited within their respective root neighborhoods in the u-plane. This leads to: (1) a method of lobing stability estimation using the growth rate boundaries, and (2) an efficient way of solving for the characteristic roots using a Taylor's series approximation. The availability of growth rate boundaries and characteristic root distribution provides an effective tool for the control of lobing in centerless grinding.
