摘要：

One of the most prevalent problems in grinding nickel-based super alloys is grinding wheel loading phenomenon which is the chip accumulation in free inter granular spaces between grains or micro-clogging on active vertices of abrasive grains. This research work studies the efficiency of acoustic emission signals in order to measure the grinding performance accompanied by wheel loading. Nickel based super alloy has been used as a work piece and experiments were carried out on different levels of wheel speed (v(s)), depths of wheel engagement (a) and work feed speeds (v(f)). The results showed that evaluation of acoustic emission parameter as well as root mean square of acoustic emission energy (AE(RMS)) and acoustic emission amplitude are the appropriate tests to predict grinding performance.
