本研究通过磨损试验台研究了铧面角与刃口磨损形式之间的关系 ,试验结果表明 :适当降低硬度、增大铧面角可以减小背棱宽度和刃口圆弧半径 ,这些是单金属犁铧形成自磨刃的必要条件
In the present study, the relationship between the flank angle and the worn form of the cutting edge was studied by using a wear test bench. The experimental results show that reducing the hardness and increasing the flank angle can reduce the width of the back edge and the radius of the cutting edge. These are single Metal plowshare formed from the grinding edge of the necessary conditions
