Abstract

The influence of the machining mode on the process of diamond finishing of boron carbide ceramic balls characterized by the allowance removal rate, the rate or decrease/increase of the deviation from spherical shape, and the heterogeneity of ball diameter within a batch has been studied experimentally. The time course of changes of a parameter was approximated, and the difference between the experimental value and the approximated value at any moment was regarded as the fraction of this parameter determined by the machining mode. We established that the fractions described above could either increase or decrease depending on the finishing conditions: the processing mode (the product of the force applied to the lap and the cutting speed), the direction of the decrease of ball diameter in the separator relatively to the direction of lower disk rotation, and the frequency of the diamond slurry feed. The most efficient combination of factors for the correction of deviation from the spherical shape and reduction of ball size heterogeneity within a batch was determined.

加工方式对碳化硼陶瓷球金刚石精加工参数的影响

摘要

实验研究了加工方式对碳化硼陶瓷球金刚石精加工工艺的影响，该工艺以余量去除率，偏离球形的速率或减小/增加，批内球直径的不均匀性为特征。 。估计参数变化的时间过程，并且随时将实验值与近似值之差视为该参数由加工模式确定的分数。我们确定上述分数可以根据精加工条件而增加或减少：加工模式（施加于棉卷的力与切削速度的乘积），相对于较低的盘旋转方向，分离器中球径减小的方向，以及金刚石浆液进料的频率。确定了纠正批次中偏离球形和减小球尺寸异质性的最有效因素组合。
