Effect of the Abrasive Grain Distribution on Ground Surface Roughness

Different grinding wheel surface conditions affect the ground surface roughness and grinding resistance during the grinding process. In addition, as the grinding wheel surface condition changes depending on the dressing conditions, the difference in the dressing conditions significantly affects the grinding characteristics. However, the dressing condition is affected by factors such as the dressing lead, depth of dressing cut, and tip shape of the dresser. Thus, optimum dressing conditions are difficult to achieve. Furthermore, even if the dressing is applied under the same dressing conditions, the grinding wheel surface condition will differ as the tip wear of the dresser progresses. There is a need for a method to quantitatively evaluate the relationship between the dressing conditions, grinding wheel surface condition, and grinding characteristics while considering the difference in the tip shape of the dresser. Thus, the relationship between the tip shape of the dresser and dressing conditions was evaluated using the dressing overlap ratio. This study aimed to evaluate the effect of different dressing overlap ratios on the grinding wheel surface condition and grinding characteristics with different grain sizes. Consequently, even if the tip shape of the dresser changes, the effect of the different dressing conditions on the grinding wheel surface condition and grinding characteristics could be quantitatively determined using the dressing overlap ratio. Furthermore, the relationship between the calculated successive cutting-point spacing, area of active abrasive grains, and grinding characteristics could be quantitatively evaluated for grinding wheels with different grain sizes.

Recent studies have shown that the cutting edge spacing and density of abrasive grains on the grinding tool surface affect the accuracy and tool life of grinding tools. However, studies on the effects of dispersion on the abrasive grain distribution have not yet been conducted. In this study, it was shown that the machining ability of a tool can be evaluated and tool life can be determined using an index of normalized information entropy for abrasive grain dispersion. However, it was difficult to continuously obtain transfer images with different loadings during the measurement of the abrasive grain distribution. Additionally, it has been revealed that in entropy evaluation, the evaluation values may remain the same even when the distribution state changes. Therefore, in this study, a device was developed to obtain a transferred image by continuously changing the loading conditions. We also examine the change in the number of divisions in the evaluation region to modify the entropy evaluation. To demonstrate the effectiveness of the proposed method, models with varying abrasive grain numbers and distributions were prepared, and the abrasive grain distributions were evaluated. After studying the entropy evaluation by simulation, an evaluation of a grinding belt in a processing experiment was conducted. It was demonstrated that evaluation using information entropy is possible in all cases by employing a method that decreases the number of divisions in the evaluation region.
