【摘要】：目的:镍基合金是一种难加工材料,在磨削时工件表面经常会出现烧伤、弹性形变和白层。本文拟通过3种不同镍基合金工件(Nickel 201,INCONEL~?600和MONEL~?400)的平面磨削实验,研究在采用微量润滑方法进行冷却时,两种不同类型磨削液对磨削力和工件表面粗糙度的影响规律。同时,研究砂轮结构对磨削过程和磨削结果的影响。创新点:通过实验比较2种磨削液对3种镍基合金工件磨削结果的不同影响,为在采用微量润滑方法时的磨削液合理选择提供有益借鉴,也为绿色制造、可持续生产或清洁生产等制造技术的发展提供技术支撑。方法:1.对每个试件表面进行多行程无火花磨削预处理,并采用浇注式冷却;2.进行单程磨削实验(图2),并采用微量润滑方法进行冷却;3.在磨削表面标记3个区域,比较在不同磨削液、工件材料及砂轮结构条件下,每个区域平均切向力和表面粗糙度值的变化情况。结论:1.磨削表面粗糙度与磨削切向力成反比,Nickel201和INCONEL~?600的表现尤为明显。2.不同的镍基合金材料工件磨削时的切向力和表面粗糙度有很大不同,MONEL~?400获得的磨削效果最好。3.初始单程磨削实验方法可以用来评价砂轮切入3个磨削区磨削状态的异同;不同磨削区域的磨削结果差异较大。4.Biocut 3000磨削液可以获得比Ecocut Mikro Plus 82磨削液更好的磨削表面,但磨削力也相应增大。5.砂轮结构的不同对磨削结果没有太大影响。
[Abstract]:Objective: nickel-based alloy is a difficult-working material. The surface of workpiece is often burned elastic deformation and white layer during grinding. In this paper, the effects of two kinds of grinding fluids on grinding force and workpiece surface roughness are studied by means of plane grinding experiments of three different nickel-based alloy workpieces Nic201kel / INCONELNLNLPHEN 600 and MONELLLLLPHON 400) when cooling with micro lubrication method, the grinding force and surface roughness of the workpiece are affected by two different kinds of grinding fluids. At the same time, the influence of grinding wheel structure on grinding process and grinding results is studied. Innovation: the different effects of two kinds of grinding fluids on the grinding results of three kinds of nickel-base alloy workpieces are compared through experiments, which provide useful reference for the reasonable selection of grinding fluids in the use of micro-lubrication method, and are also useful for green manufacturing. The development of manufacturing technologies such as sustainable production or cleaner production provides technical support. Method 1: 1. The surface of each specimen was pretreated with multi-stroke non-spark grinding and cast cooling was used. A single-pass grinding experiment was carried out (fig. 2) and micro-lubricating method was used for cooling. The average tangential forces and surface roughness values of different grinding fluids, workpiece materials and grinding wheel structures were compared in three regions marked with grinding surfaces. Conclusion 1. The surface roughness of grinding is inversely proportional to the grinding tangential force. The performance of Nickel201 and INCONEL~?600 is especially obvious. The tangential force and surface roughness of different Ni-base alloy workpiece grinding are very different. The initial single-pass grinding experiment method can be used to evaluate the similarities and differences of grinding state of grinding wheel cutting into three grinding areas. 4. Biocut 3000 grinding fluid can obtain better grinding surface than Ecocut Mikro Plus 82 grinding fluid. But the grinding force also increases correspondingly. The different structure of grinding wheel has no great influence on grinding results.
