在外圆切入磨削时,采用径向磨削力、磨削功率或金属实际切除率的稳定系统不排除为保证被磨工件质量在加工循环结束时降低磨削用量的必要性。分析各种不同的加工循环可以认为,在加工过程中存在着与工件质量指标和工艺参数有关的磨削用量之最佳变化规律。加工循环可根据工件几何形状误差、波纹度、粗糙度、尺寸精度和烧伤等指标最佳化。对于宽砂轮来说,工件横截面内的几何形状误差是其主要质量指标在外圆切入磨削时,此项参数决定于工件和砂轮的旋转精度、磨削用量、振动程度和砂轮不平衡量等等。由磨削用量所决定的极限形状误差约相等于(在数量上)工件每转的进给量。
Stabilization system using radial grinding force, grinding power or actual metal removal rate does not preclude the need to reduce the amount of grinding required to ensure the quality of the workpiece to be milled at the end of the machining cycle during the cutting of the outer circle. Analysis of a variety of processing cycles can be considered in the process of existence of the workpiece quality indicators and process parameters related to the best change in the amount of grinding. Machining cycle can be based on the workpiece geometry error, waviness, roughness, dimensional accuracy and burn indicators such as optimization. For wide wheel, the geometric errors in the cross section of the workpiece is the main quality index when cutting in the outer circle, this parameter is determined by the rotation accuracy of the workpiece and the grinding wheel, the amount of grinding, the degree of vibration and the wheel unbalance, etc. . The limit shape error, determined by the amount of grinding, is approximately equal to (in number) the feed per revolution of the workpiece.
