“…Some attempts were previously made to study the AWJT process. Experimental investigations by the pioneer of this technique, Hashish, give very useful information about fundamentals for acquaintance of AWJT [1,2,10,11]. As the first investigations, Hashish [1] discussed the effects of different parameters on the turning performance.…”

“…Results illustrate the great potential of AWJT to produce near-net-shape parts at fast material removal rates. A visualization study [10] pointed out how the material removal takes place at the workpiece face and the process involves a mechanism of step formation and removal similar to the linear cutting with abrasive waterjet. Moreover, the observations suggest that the abrasive waterjet does not undergo any significant radial deflection in the region where material removal takes place.…”

The effects of the main operational machining parameters on the material removal rate (MRR) in abrasive waterjet turning (AWJT) are presented in this paper using a statistical approach. The five most common machining parameters such as water pressure, abrasive mass flow rate, cutting head traverse speed, workpiece rotational speed, and depth of cut have been put into a five-level central composite rotatable experimental design (CCRD). The main effects of parameters and the interaction among them were analyzed by means of the analysis of variance (ANOVA) and the response surfaces for MRR were obtained fitting a second-order polynomial function. It has been found that depth of cut and cutting head traverse speed are the most influential parameters, whereas the rotational speed is insignificant. In addition, the investigations show that interactions between traverse speed and pressure, abrasive mass flow rate and depth of cut, and pressure and depth of cut are significant on MRR. This result advances the AWJT state of the art. A complete model discussion has been reported drawing interesting considerations on the AWJT process characterising phenomena, where parameters interactions play a fundamental role.

“…It was reported that the final diameter of the turned part is usually more than the desired diameter because of the jet deflection and its instability 10 . However, from a visualization study, Ansari et al 11 pointed out how the abrasive waterjet does not undergo any significant radial deflection in the region where material removal takes place. Axinte et al utilized AWJT as an efficient method to profile and dress grinding wheels and proved its technological and economical capability 5 .…”

Geometrical error in abrasive waterjet turned parts is an important challenge towards the abrasive waterjet turning process commercialisation. A Systematic study has not been done yet to investigate the effects of process parameters on geometrical error in abrasive waterjet offset-mode turning. In this paper, a comprehensive study has been performed to investigate the influence of several machining parameters on the geometrical error (part diameter percent error) in turning AA2011-T4 aluminum alloy round bars. Water pressure, cutting head traverse speed, workpiece rotational speed, abrasive mass flow rate and depth of cut were considered as the main machining parameters in a five levels statistical experimental design. Basing on central composite rotatable design (CCRD), a total of 52 experiments was carried out. The main effects of the parameters and interactions among them were analyzed based on the analysis of variance (ANOVA) technique and the response contours for the part geometrical error were obtained using a quadratic regression model (i.e. RSM). The model predictions were found to be in good agreement with experimental data. Furthermore, among the significant parameters, pressure, depth of cut and traverse speed are the most influential parameters, with percent contribution of almost 25% each. Abrasive mass flow rate places as the least influential parameter with a percent contribution of 4%.
