针对三种不同的工件材料,用量纲分析与正交回归分析的方法,对缓进给磨削深直沟槽时的砂轮边角磨损量进行了试验研究。提出了应用曲线拟合等手段计算砂轮边角磨损量的方法,从无量纲特性数的角度揭示了砂轮边角磨损的特性与规律,并得到了砂轮边角磨损量的回归方程。
Aiming at the three kinds of different workpiece materials, the wear amount of the corner of the grinding wheel at the time of slowly feeding the deep straight groove is studied with the method of dimension analysis and orthogonal regression analysis. A method of calculating the wear amount of the corner of the wheel by means of curve fitting is put forward. The characteristics and rules of the corner wear of the wheel are revealed from the dimensionless number of features. The regression equation of the wear amount of the corner of the wheel is obtained.
