【摘要】 本实验研究的目的是通过对不同的加工参数对热压成型的金刚石刀具磨损量影响的分析,进而确定较理想的加工参数,实现高效率的加工。实验采用三维雕刻机铣削的工作原理,通过正交实验的设计方法,并制定不同的加工参数,刀具的磨损量应用高精密电子天平测得,刀具表面磨损形态应用体式显微镜观测。实验数据表明,对金刚石刀具磨损量影响的主要参数是切削深度,其次是进给速度,最后是主轴转速。刀具底面磨损比侧面严重,底面磨损主要以脱落为主,侧面主要以冲击破碎为主。更多还原

【Abstract】 The purpose of this experiment analyses the worn mass of diamond by the different parameters and the tool is made by heat-press,so it can help us find the better processing parameters and increase production efficiency.In the experiment we use the three-dimensional of carving machine.Through the design of orthogonal experimental different processing parameters are designed.The worn mass of diamond mill is measured on the precise balance and the tool of worn surface is analysed with Leica MZ95 stereo microscope.The experiment data shows that the cutting depth is the greatest influence on worn weight of cutting tool,second is feed speed and last is rotative speed of principal axis.The wear of diamond mill is more serious on the underside than on side.Worn form on bottom is mainly diamond fallen off bond and side is mainly crashed diamond.更多还原
