This study proposed a new magnetic abrasive finishing (MAF) method, in which 6-axis robot with machining tool was used to polish the inner surfaces of curved tubes. We have also developed jig, can be fixed at front robot, rotating freely and suitable for polishing In this study, we focused on investigating parameters initial stage precision stage. Based characteristics parameters, multi-stage M...
Polishing technology is a final surface finishing process. The main aim is the removal of the machining marks to make the surface bright and clean. Polishing is often difficult to realize automatic mechanical polishing due to the polishing quality requirements and workpiece shape. Aiming at the problem, an automatic polishing technology has been proposed. In the paper, a new polishing path dete...
INTRODUCTION Hard and temperature resistant materials are used for mold manufacturing of optical glass lenses. These materials are not machinable by ultra precision diamond milling and turning processes. For example hardened steel or tungsten carbide can be ground in optical quality regarding shape but additional polishing is necessary to guarantee the high requirements for optical surface qual...
Fluid jet machining has been widely used in of hard-brittle materials. However, the diffusion a flow significantly affects erosion capacity. Magnetorheological (MR) fluid considered to take role pure water for carrying abrasive particles, due its better concentration when external magnetic field is applied. The present investigation focuses on characteristics magnetorheological jet, which are i...
