“…WED turning and AWJ turning were considered for machining of hybrid metal matrix composites. The roughness values of samples decreased while the rotational speed increased and those of WED turned were comparatively superior to AWJ ones [7].…”

“…Variation of microhardness and residual stresses were founded as tensile residual stresses in WED turning because of the thermal erosion process, but they become negligible when increasing the depth from the surface towards the core of the workpiece. In AWJ turning operation were founded compressive residual stresses due to pinning effect and no role of heat formation [7].…”

Abrasive water jet machining (AWJM) is one of the most important method used in cutting different types of materials: alloy sheet, marble, glass, rocks. This process is used in the aeronautic, automotive, metallurgy industries and even in some art techniques and textile industry. The method consists in transforming the kinetic energy of a solid particle directed with water jet at a high pressure to remove material through erosion and abrasion. AWJM is low cost equipment compared to other conventional cutting technologies. This paper is an attempt to review the achievements made in AWJM technology for different hardness materials.

“…Machining with AWJ can be applied for turning, drilling and milling as per requirement of the industry. However, the surface roughness of the AWJ machined surface is high compared to the other machining processes reported by most of the authors [15][16][17]. This is due the fact that the ploughing nature of cutting was observed with plastic deformation.…”

The conventional machining of engineering hard materials like composites is a challenging task due to rapid tool wear and high machining cost. In this context, the non-conventional machining such as abrasive waterjet cutting is mostly utilized for the cutting of such hard materials due to its tremendous machining outcomes. Here an attempt is made to cut the previously developed sample of hybrid metal matrix composite A359/B4C/Al2O3 by abrasive waterjet machining process. Three different samples with change proportions of reinforcement from 2% to 4% were used in this study to create the flat machined surfaces. The surface roughness profile and 3D surface detailing are generated through the microprof FRT machine and inbuilt measuring sensor. Result revels that rough cutting with the average surface roughness value ranges from 7 to 9 µm for the selected samples. The machined surface is full of cutting traces with some of macro pores of size 1.2 mm to 1.8 mm observed by 3D profile views.

“…For these materials, research potential arises in relation to their machining process. Due to the variability of these materials, there is no exact general solution [15]. Various factors are taken into account in relation to the acceptability of the machining process, which depend on the setup parameters and the physical properties of the chosen material.…”

Effect of Waterjet Machining Parameters on the Cut Quality of PP and PVC-U Materials Coated with Polyurethane and Acrylate Coatings

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.
