Abstract:仿生研究表明,凹坑、沟槽等微织构具有减阻、降噪、自清洁等许多优秀的性能,实现微织构的精密加工对于提高产品性能具有重要意义。然而,目前的微织构加工方法存在着基准面适应性差,加工成本高以及加工周期长等问题。以V型槽减阻织构为目标织构,提出了一种分层椭圆振动辅助切削加工微织构的方法,实现了工件表面上V型槽的加工。首先,根据椭圆振动的轨迹特点,建立了V型槽的形貌参数模型,据此推导出最大残留高度与切削速度之间的关系;其次,根据V型槽的加工深度,设计了分层椭圆振动辅助切削的走刀轨迹;最后进行了V型槽加工试验,对不同的加工方式所获得的V型槽进行对比,验证了关于形貌模型的理论分析的正确性,表明分层椭圆振动辅助切削加工V型槽时具有降低切削力和抑制槽沿毛刺产生的作用。
