摘要
针对大尺度316L不锈钢台板端面磨削加工中工件表面质量不稳定的问题,利用ANSYS/LS-DYNA有限元分析软件,建立了单颗磨粒磨削有限元模型,仿真分析得到磨削速度和磨削深度对磨削力和材料去除率的影响规律。基于仿真结果,以提高磨削表面质量与材料去除率为目的,利用内径147 mm、外径197 mm的杯型白刚玉砂轮,对面积约20 m^(2)的大尺度不锈钢台板表面进行端面磨削正交实验。实验结果表明,砂轮转速选用1 600 r/min,磨削深度控制在20μm左右,可以获得无烧伤且表面粗糙度R≤0.8μm的端面磨削效果。
To solve the unstable surface quality problems of large-scale 316L stainless steel plate end face grinding,the single-grain grinding finite element model is established with the help of ANSYS/LS-DYNA finite element analysis software.The influence of grind speed and depth on the grinding force and material removal ratio is obtained.According to the simulation result,the 316L stainless steel plate with an area of about 20 m^(2) is subjected to the end face grinding orthogonal experiment by using a cup-shaped white corundum grinding wheel with an inner diameter of147 mm and an outer diameter of 197 mm.The experimental result shows that the grinding wheel rotational speed is1 600 r/min,and the grinding depth is controlled at about 20 μm,which can achieve the grinding effect that surface roughness is R≤0.8 μm without grinding burns.
