| 摘 要： | 视线锯的磨粒为圆锥状，考虑磨粒突起高度为正态分布，同时用截断高斯分布模型表示线锯的磨损，根据线锯和工件的相对运动，给出了粗糙度的理论模型和预测方法．此方法通过求得不同突起高度的磨粒残留痕迹的交点，得到加工工件的最终轮廓，从而得到表面粗糙度．实验证明，此方法所得表面粗糙度与实测的表面粗糙度一致。

| Abstract: | A new method for modeling and predicting surface roughness generated in diamond wire-sawing is developed. This method takes into consideration the random distribution of the grain protrusion heights and a truncated Gaussian distribution model is developed to relate the wear of wire-saw. The intersecting points of the traces of any two grains with different heights are found. Then the workpiece profile and the surface roughness are determined. The tested result shows that the roughness obtained based on the developed method is consisrant with the measured one. |
