摘要:
为了提高薄壁回转结构加工面余量分布的均匀性,改善表面质量,提出了一种磨头相对工件作圆平动的方法,并采用数值分析方法研究了加工间隙内流场、电场的分布规律.数值分析结果表明,平动运动消除了加工间隙内的负压区、空穴区和分股流,避免了加工面两侧的电场畸变.基于数值分析开展了工艺试验,工艺试验结果表明,采用平动偏心距为0.1 mm,平动周期为6 s的优化平动运动参数,加工面余量误差可控制在5 μm以内,表面粗糙度Ra达到0.21 μm.
Abstract:
To improve the uniformity of allowance distribution and the surface roughness of the machined surface in the thin-wall revolution structure, a method with grinding head circular translational moving relative to the workpiece was proposed, and the distributions of flow field and electric field in the machining gap were studied by numerical analysis. The numerical analysis results show that the negative pressure region, the cavitation region, and the split flow in the machining gap are eliminated by the circular translational moving, besides, the electric field distortions in both sides of the machined surface are avoided. Experiments are carried out based on the numerical analysis. The experimental results show that the machined surface allowance error of less than 5 μm, and the surface roughness of 0.21 μm can be obtained by adopting optimized circular translational moving parameters, i.e. translational eccentricity 0.1 mm, translational cycle 6 s.
