一、概述磨削力是直接说明磨削过程中砂轮磨削性能的重要参数,磨削力的大小直接反映了作用在砂轮磨粒切刃上的负荷的大小。所以,可以把磨削力的变化作为评价砂轮切削性能的指标;磨削力的法向分量将影响工艺系统的弹性变形,使工件产生残余留量、颤振等现象,对工件的尺寸精度和加工表面光洁度产生不利的影响;磨削力的切向分量的大小直接影响机床功率的选择,同时,磨削过程中消耗的能量大部分转变为热量,使磨削温度升高,从而影响工件尺寸精度及表面质量(烧伤等)。因此,磨削过程中力参数的研究一直受到重视。
First, an overview of grinding force is a direct description of the grindstone grinding process grinding performance of an important parameter, the size of the grinding force directly reflects the role of grinding wheel abrasive cutting edge load size. Therefore, the change of grinding force can be used as an index to evaluate the cutting performance of grinding wheel. The normal component of grinding force will affect the elastic deformation of the process system, resulting in the residual capacity and flutter of the workpiece. The dimensional accuracy and Machining surface finish adversely affect the size of the tangential component of the grinding force directly affects the machine power selection, while most of the energy consumed in the grinding process into heat, the grinding temperature, thus affecting the size of the workpiece Accuracy and surface quality (burns, etc.). Therefore, the study of the force parameters in the grinding process has been paid more attention.
