“…With the correct choice of the cutting head traverse speed, the walls of the material to be cut are parallel, which means that there is no narrowing of the cut profile, and the surfaces are smooth without undulations [20]. However, if the traverse speed is high, a V-shaped cut is created.…”

The article focuses on the machining of polymeric materials polypropylene (PP) and un-plasticized poly vinyl chloride (PVC-U) after surface treatment with polyurethane and acrylate coatings using waterjet technology. Two types of waterjet technologies, abrasive waterjet (AWJ) and waterjet without abrasive (WJ), were used. The kerf width and its taper angle, at the inlet and outlet of the waterjet from the workpiece, were evaluated. Significant differences between AWJ and WJ technology were found. WJ technology proved to be less effective due to the creation of a nonuniform cutting gap and significant burrs. AWJ technology was shown to be more efficient, i.e., more uniform cuts were achieved compared to WJ technology, especially at a cutting head traverse speed of 50 mm·min−1. The most uniform kerf width or taper angle was achieved for PP + MOBIHEL (0.09°). The materials (PP and PVC-U) with the POLURAN coating had higher values of the taper angle of the cutting gap than the material with the MOBIHEL coating at all cutting head traverse speeds. The SEM results showed that the inappropriate cutting head traverse speed and the associated WJ technology resulted in significant destruction of the material to be cut on the underside of the cut. Delamination of the POLURAN and MOBIHEL coatings from the base material PP and PVC-U was not demonstrated by SEM analysis over the range of cutting head traverse speeds, i.e., 50 to 1000 mm·min−1.

“…In literature, it is established that reverse taper (negative taper angle) occurs mainly due to the cutting speed, when its value is lower than the critical one that is required in order to ensure a smooth cut surface with almost zero tapering, under specific machining parameters. As a rule of thumb, it can be said that higher from the optimal cutting speeds leads in typical V-shaped taper, lower cut speeds in reverse taper, while, in cases of very thick workpieces, barrel like taper may occur (Krajcarz et al, 2017).…”

Abrasive Waterjet (AWJ) machining is considered an excellent alternative to conventional machining processes due to its superb machining characteristics. More specifically, Abrasive Waterjet drilling is nowadays a promising non-conventional process for obtaining high quality holes. In the present study, drilling experiments based on Taguchi L9 orthogonal design method were conducted via AWJ on carbon fiber reinforced polymer (CFRP) plate at various waterjet parameters, namely, different pressure, abrasive mass flow rate and standoff distance values. The purpose of the experiments was to investigate the impact of these process parameters on the quality of holes. The hole quality was determined by measuring the hole diameter error as well as the hole taper. The optical evaluation was implemented with the use of optical microscope and special measuring software. The ANOVA analysis of the results showed a significant influence of standoff distance regarding the hole diameter error and a combined influence of waterjet pressure and standoff distance regarding the hole taper. Furthermore, the optimal process parameter values for the optimization of the hole diameter error and hole taper were determined. The hole quality in terms of defects appearance was also quantitatively inspected, through optical imaging.

The article presents the basic parameters characterizing the abrasive water jet cutting, such as: water pressure (pw), cutting speed (vf), abrasive mass flow rate (ma) and the distance between forming nozzle and the cut material (l). Each of the mentioned parameters of the cutting process has been described in a separate subsection. The authors of the article focused primarily on the aspects related to the possibility of achieving maximum efficiency of the machining process while maintaining the assumed quality of cutting for individual cutting parameters. A detailed analysis of the topic was enabled the authors own research and an available literature on this subject. A closer understanding of the phenomena accompanying the abrasive waterjet cutting (AWJ) process and obtaining characteristics that would describe the influence of the tested output parameters in the function of input parameters will enable optimization of AWJ cutting process.
