摘要: 金刚石滚轮在砂轮的成型修整中发挥重要作用,其磨粒磨损是影响滚轮寿命与修整质量的一个主要因素,磨粒的有效排布可以减少磨粒磨损,但目前研究多集中于磨粒排布对单层砂轮的磨削影响,并不适用于磨料堆积砂轮,具有局限性。本文研究滚轮表面磨粒排布对修整砂轮的过程影响,通过进行错位、阵列和叶序三种排布滚轮对砂轮成型修整过程的有限元仿真与实验验证,以磨削力为主要指标,得出结论:在金刚石滚轮对砂轮的修整过程中,颗粒的规则排布会对磨削力产生影响,其中阵列排布磨削力最大,错位排布次之,叶序排布磨削力最小。叶序排布相较于错位与阵列排布,可以有效减少滚轮表面磨粒磨损,提高滚轮的修整性能与寿命。Abstract: The diamond roller plays a crucial role in the formation and dressing of grinding wheels, with its abrasive wear being a significant factor that affects both the roller's lifespan and the quality of dressing. Effective arrangement of abrasive particles can help reduce this wear. However, current research primarily focuses on studying the impact of abrasive layout on single-layer grinding wheels, which limits its applicability to abrasive accumulation grinding wheels. This paper investigates how the arrangement of abrasive grains influences the process of dressing a grinding wheel. By employing finite element simulation and experimental verification during the forming and dressing processes using three types of roller arrangements (dislocation, array, and phyllotactic pattern), we evaluate their effects on grinding force as our main indicator. Our findings reveal that during the wheel dressing process, regular particle arrangement significantly impacts grinding force; specifically, array arrangement results in higher forces compared to dislocation arrangement while phyllotactic pattern yields lower forces. Furthermore, when compared to dislocation and array arrangements, phyllotactic pattern arrangement effectively reduces abrasion on the roller surface while enhancing both dressing performance and service life.
