磨粒排布对加压内冷却砂轮磨削性能的影响
Effect of Abrasive Arraying Forms on the Grinding Performance of a Pressurized Internal-cooling Grinding Wheel
摘要
Abstract
In view of the effect of the abrasive arraying forms on the grinding efficiency and performance,the pressurized internal-cooling grinding wheels with random or ordered abrasive are designed and prepared.Based on the surface morphology detection technology and image identification technology,the 3D finite element model for grinding superalloy GH4169 is established.The grinding experiments of superalloy GH4169 are performed by adopting the prepared wheels,the effects of the abrasive arraying forms on the grinding performance are revealed,grinding force,temperature,machined surface roughness and surface topography are studied.The results show that:compared with the wheel with random abrasive,wheel with ordered abrasive leads to better machined surface quality,smaller grinding force,lower grinding temperature and surface roughness,moreover cleaner surface morphology.关键词
