Pressure conditions during the immersed tumbling process

Abstract

An approach to improve the tool wear behaviour of milling tools made of cemented carbide is a defined cutting edge preparation usingthe immersed tumbling process. One significant factor that influences cutting edge preparation is the effective pressure generated by the relative movement of the cutting tools and the abrasive particles. However, the development and influence of the process pressure has been discussed almost exclusively based on machining and preparation results. For a profound process understanding a wireless force measurement system was designed and the pressure forces of two media were examined. The influences of the used lapping media, the velocityas well as the depth of immersion using a simplified linear movement were analysed. The results provide information about the pressure conditions that change in the real process.
