Abstract

Abrasive waterjet (AWJ) cutting is one of the most recently developed manufacturing technologies. This technology is being increasingly used in various industries especially in gear manufacture. This paper presents the investigation of abrasive water jet nozzle height on cutting parallelism of mild steel gear. There are three objectives of this project that needs to be accomplished. Firstly, to investigate the cutting taper on the mild steel work piece using abrasive water jet machining. Second, to select the best height of the nozzle during cutting process of cutting parallelism and lastly to assess cutting edge condition at different taper ratio. There are 10 mm and 20 mm thickness of mild steel work pieces are machining and 15 readings of cutting width are taken for every size of the sample. From the main effect plot Minitab software analysis, the best nozzle height is proven to get the parallel cutting kerf. The mean value indicated that there is a significant difference height between 5mm, 10mm,and 15mm nozzle height of the mild steel work piece. The lowest nozzle height will produce a smaller erosion on cutting taper and better surface finish. The best selection for waterjet cutting of nozzle height during machining is 5mm because it produce a lowest angle taper and produced a high kerf quality.
