一、引言构成砂轮的细小磨粒的切削作用是金属磨削的基础,故单颗磨粒磨削研究成为认识复杂磨削作用的一种重要手段。许多学者曾用它对普通精密磨削的磨粒磨耗破碎、切屑形成及伴随产生的力、变形等进行研究。而本试验研究是以重负荷钢坯磨削为对象进行的。 I. INTRODUCTION The cutting action of the fine abrasive grains that constitute the grinding wheel is the basis of metal grinding. Therefore, the study of single abrasive grain grinding becomes an important method to recognize the effect of complex grinding. Many scholars have used it for ordinary precision grinding abrasive wear and tear, chip formation and accompanying force, deformation, etc. were studied. However, this experimental study is based on heavy duty billet grinding.
