On the base of the constant removal rate of the metal material, the motion model of tangential point tracing grinding of Non-round parts should be given respectively according to type of the parts.
基于恒金属去除率的原则，根据零件的特点分别建立了非圆零件切点跟踪磨削的运动模型。
2
The tangential coefficient for non-sliding oblique collision is introduced.
该文对无滑斜碰撞的研究引入了切向系数。
3
Swelling efficiency in vertical direction of compressed direction was the smallest in tangential, the biggest in radial and middle in non standard direction compression.
