【摘要】 随着工业技术的发展,数控车床在工业加工中的应用越来越广泛。数控加工过程中,一般对刀具刀尖的圆弧半径r、主偏角kr、刀尖距离零件中心高的偏差尺寸等几何参数进行重点探究,以提高工件表面的光滑程度、减缓刀具磨损,便于对刀具的切削力进行控制。刀具几何参数对加工零件的轴向尺寸误差和纵向尺寸误差产生影响,加工零件的表面形状也会出现变化。本文重点探究了数控车床刀具刀尖圆弧半径对零件加工精度的影响,便于零件加工过程中采取有效的措施。更多还原

【Abstract】 with the development of industrial technology,numerical control lathe processing,the application of more and more widely in the industry. Nc machining process,the general of tool tip arc radius r,the main Angle of kr,high point distances from the center of the parts size deviation,and other key geometric parameters to explore,in order to improve the smooth degree of surface,reduce tool wear,easy to control the cutter cutting force. Tool geometric parameters on the machining parts of the axial size error and longitudinal dimension error,machining parts surface shape will change. This paper mainly explores the CNC lathe tool tip arc radius influence on precision parts processing,to take effective measures in the process of machining parts.更多还原
