New Construction

Quality of the technological part is one of the major problems of modern machine manufacturing. In many cases, components are manufactured from new construction materials with specific properties that are considered difficult to machining applying conventional technologies. Hence, to search for new technologies, including high-pressure abrasive water jet cutting in the context of the S355J2H steel elements manufacture, while maintaining the quality requirements of the machining, is the need. The results of tests on the accuracy of components made of S355J2H steel are presented as dependent on the water jet pressure, cutting feedrate and the amount of abrasive dozed, with constant element thickness. The accuracy of the design measure – regardless of dimensional accuracy – was the magnitude of the lateral sagging of the cut workpiece resulting from the specific mechanism of water jet removal mechanism.

Master Model

The main objective of the paper consists in remanufacturing of a part, through Abrasive Water Jet Cutting, using a method of reverse engineering based on 3D scanning. The characteristics of this process, the equipment and the main applications are presented. The research starts with manufacturing of a master model made by CFRP. This master model is a complex part cut by abrasive water jet cutting. In scanning process was used the 3D Scanner Artec Space Spider and the point cloud was processed using Artec Studio 11 software. By using this new 3D model was manufactured a new part, with the same setup. The quality characteristics (accuracy and surface quality) of this part was compared with the master model. The paper presents the advantages and disadvantages of this reverse engineering method applied on abrasive water jet cutting process.

Abstract Since 1989, SCK•CEN is dismantling the BR3 (Belgian Reactor no3). During these 11 years of decommissioning, a lot of experience is gained in the field of remotely controlled cutting techniques for high active parts and decontamination techniques of highly contaminated parts. Mechanical cutting techniques (circular saw and band saw) were used for cutting the reactor Pressure Vessel (RPV) and its internals. For some large components in the reactor building, like the steam generator, the pressurizer and the Neutron Shield Tank, a new tool, the High Pressure Abrasive Water Jet Cutting will be used to cut activated and contaminated pieces with material thicknesses ranging from 20 to 170 mm. Deliverance of the cutting equipment is foreseen in the summer of 2001. Cold tests and training sessions for the operators will then take place and by the beginning of 2002 the cutting equipment will be installed in the reactor pool inside the controlled area to start the actual work.

Abstract The present paper discusses the impact of the speed of an abrasive water jet cutting process on some surface properties and morphology of the S235JRG1 steel. The values of the cutting speeds used for the analysis were of 100, 150 and 200 mm.min−1 respectively. A contact profile method was used to analyze the surface roughness during the conducted tests. In this study, the observed surface roughness parameters were the Ra, Rt and Rz, respectively. At the same time, these parameters were measured in three positions, i.e.: at the inlet (A), in the middle (B) and at the exit position (C) of the water jet nozzle with respect to the machined material. The experimental study showed that the roughness of the surface reached higher peaks and was more pronounced at the exit position (C) of the water jet. Similarly, it was also concluded that a better quality of the surface was achieved at a speed of 150 mm.min−1.

Technological Quality

Despite extensive knowledge of the cutting methods described, no universal method has been developed so far for evaluating the technological quality of elements shaped by different cutting processes. The aim of the research described in this article was to fill this gap and to propose the author’s methodology for the assessment of the technological quality of the surface of X5CRNI18-10 steel shaped as a result of laser cutting and abrasive water jet cutting. A synthetic index of technological quality assessment of the surface after cutting CTQ (cutting technological quality) was proposed. Three groups of factors were taken into account in the assessment of technological quality of the surface after cutting: selected surface texture parameters (arithmetic mean deviation of the surface Sa and total height of the surface St), results of measurements of dimensional accuracy of cut elements (length deviation LD and width deviation WD) as well as indicators of surface morphology estimated on the basis of microscopic images of the surface after cutting (deformation intensity DI and identification of cutting zones ICZ). On the basis of CTQ values determined, the cutting results of both cutting methods were compared. The analyses presented in this paper proved that the CTQ index can be effectively used to compare the results of a cutting process conducted using different methods and under different conditions. The developed CTQ index is a universal valuation tool, allowing for quantitative evaluation of features related to the technological quality of cutting process results.
