Abstract
Abrasive waterjet machining (AWJM) is widely used in the industries with the distinct advantages of no thermal distortion, high flexibility, small cutting forces, etc. In this work, the influence of abrasive waterjet milling (AWJ milling) process parameters such as waterjet pressure (P), traverse rate (TR), abrasive flow rate (AFR) and standoff distance (SOD) on the depth of cut (DOC), material removal rate (MRR) and surface roughness (Ra) were studied. An attempt has also been carried out to monitor the AWJ milling using two sensors namely, acoustic emission (AE) and cutting force dynamometer. The acquired AE sensor signal is analysed in the time- and frequency domains, whereas the cutting force signal is analysed in the time domain. The result indicated that AE and cutting force signals are influenced by the changes in the input process parameters conditions.
