Abstract

Boring is also known as internal turning operation. Which is used to increases the internal diameter of the hole. Boring or internal turning operation is very critical manufacturing process. Which create surface roughness; vibration, noise, and tool wear related problems. In the boring operation of machining vibration is very critical problem In this work, boring tool with viscoelastic material such as Polytetrafluoroethylene (PTFE), Polyvinyl Chloride (Polyurethane) [PVC (Pu)], and Butyl rubber is mounted on boring tool as nut and bush arrangement. Boring operation was performed on EN8 material work piece with and without viscoelastic material damper on CNC machine. Taguchi optimization technique applied to determine the optimum boring parameters: spindle speed, feed rate, and depth of cut. Experimental results are appraised as surface roughness. PTFE gives better result as compare to other viscoelastic material PVC and Rubber. The surface roughness value decreases due to installation of PTFE damper on boring tool.

采用被动阻尼材料的数控镗床，优化镗床参数以实现最小表面粗糙度

镗孔也被称为内车削操作。用来增加孔的内径。镗孔或内车削工序是非常关键的制造工序。产生表面粗糙度;振动、噪音、刀具磨损等相关问题。在镗刀加工过程中，振动是非常关键的问题。在本工作中，镗刀采用粘弹性材料如聚四氟乙烯(PTFE)、聚氯乙烯(聚氨酯)[PVC (Pu)]、丁基橡胶等作为螺母和衬套布置安装在镗刀上。在数控机床上对带粘弹性材料阻尼器和不带粘弹性材料阻尼器的EN8材料工件进行了镗孔加工。应用田口优化技术确定最佳镗削参数:主轴转速、进给速度和切削深度。实验结果用表面粗糙度来评价。与其他粘弹性材料PVC和橡胶相比，PTFE具有更好的效果。由于在镗刀上安装了聚四氟乙烯阻尼器，表面粗糙度值降低。
