Model Predictions

Predictive models for the major cutting performance measures, such as the kerf taper and depth of cut, are developed for both straight-slit cutting and profile cutting by an abrasive waterjet. The plausibility and predictive capability of the models are assessed and verified by comparing the model predictions with the corresponding experimental data. Very good correlations between the predicted and experimental results have been found, which confirm the adequacy of the models for use in process planning.

An experimental investigation is presented of the various cutting performance measures, such as the kerf taper and depth of cut, in profile cutting on an 87 per cent alumina ceramic by abrasive waterjet (AWJ) over a wide range of process parameters. It is found that the taper angles on the two kerf walls produced in cutting AWJ of profiles are different in magnitude and exhibit different trends as the profile curvature radius varies. Moreover, the depth of cut increases with an increase in the curvature radius and approaches its maximum in straight cutting. The other process variables affect the cutting process in a way similar to that in straight cutting. Recommendations are finally made for the selection of process parameters in AWJ profile cutting of alumina ceramics. Predictive mathematical models for the major cutting performance measures that are essential for the optimization of the AWJ cutting process are reported in the subsequent part of this investigation.

The cutting performance in abrasive waterjet (AWJ) multipass cutting with and without controlled nozzle oscillation is presented based on an experimental investigation cutting an 87% alumina ceramic. The cutting capacity in terms of the depth of cut and the kerf geometrical features is analyzed with respect to the process variables. It is found that multipass cutting is a viable means to increase the cutting performance and application domain of this technology, while a further increase in the cutting performance can be made by using a controlled nozzle oscillation technique.

Waterjet Machining

Abrasive water jet machining is a proficient alternative for cutting difficult-to-machine materials with complex geometries, such as austenitic stainless steel 304L (AISI304L). However, due to differences in machining responses for varied material conditions, the abrasive waterjet machining experiences challenges including kerf geometric inaccuracy and low material removal rate. In this study, an abrasive waterjet machining is employed to perform contour cutting of different profiles to investigate the impacts of traverse speed and material thickness in achieving lower kerf taper angle and higher material removal rate. Based on experimental investigation, a trend of decreasing the level of traverse speed and material thickness that results in minimum kerf taper angle values of 0.825° for machining curvature profile and 0.916° for line profiles has been observed. In addition, higher traverse speed and material thickness achieved higher material removal rate in cutting different curvature radii and lengths in line profiles with obtained values of 769.50 mm3/min and 751.5 mm3/min, accordingly. The analysis of variance revealed that material thickness had a significant impact on kerf taper angle and material removal rate, contributing within the range of 69–91% and 62–69%, respectively. In contrast, traverse speed was the least factor measuring within the range of 5–18% for kerf taper angle and 27–36% for material removal rate.
