Abrasive Cutting

Water jet cutting is an unconventional technology used for materials processing. Abrasive water jet cutting has become a highly developed industry technology. Its development has been favored by the fact that abrasive water jet cutting can be used in practically all areas in which solids are processed stone, glass, plastics, composite materials and metals. It is known to be one of the most versatile and rapid cutting methods that can be applied to process a greater variety of materials such: metallic materials, non-metallic materials. By comparing with the classical technologies, the water jet cutting presents the following advantages: very low side forces during the machining; it is rapid; it is silent; no thermal distortion, high flexibility and has a good cutting accuracy and minimal burrs. The aim of the present paper is to present the results of the study regarding the influence of the distance between the cutting head and working sample processed by abrasive water jet cutting on the surface roughness and dimensional accuracy of the processed part.

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.

Water jet cutting is an unconventional technology used for materials processing. It is known to be one of the most versatile and rapid cutting methods that can be applied to process a greater variety of materials such: metallic materials, non-metallic materials, stone, glass etc. By comparing with the classical technologies, the water jet cutting presents the following advantages: very low side forces during the machining; it is rapid; it is silent; no thermal distortion, high flexibility and has a good cutting accuracy and minimal burrs. In this paper the influence of the high pressures on the surface quality of the workpieces processed by water jet abrasive cutting is presented. The studied parameters were as follows: width of the processed surface at the jet inlet (Li), width of the processed surface at the jet outlet (Lo), deviation from perpendicularity (u), inclination angle (α) and roughness (Ra).

High-pressure abrasive water jet cutting is a cold and non-traditional method, with many advantage which the traditional processing do not have.The traditional method of cutting marble have rough sections, poor dimensional accuracy, large seam, high tool cost and the processing efficiency is low. Can be considered high-pressure abrasive water jet cutting to improve its traditional cutting defects. This article explores the use of the pre-mixed abrasive water jet cutting in the marble, and its comparison with traditional methods, highlighting the advantages which the pre-mixed abrasive water jet cutting in the marble.

Abstract The paper deals with a study of relations between the measured Ra, Rq, Rz surface roughness parameters, the traverse speed of cutting head v and the vibration parameters, PtP, RMS, vRa, generated during abrasive water jet cutting of the AISI 309 stainless steel. Equations for prediction of the surface roughness parameters were derived according to the vibration parameter and the traverse speed of cutting head. Accuracy of the equations is described according to the Euclidean distances. The results are suitable for an on-line control model simulating abrasive water jet cutting and machining using an accompanying physical phenomenon for the process control which eliminates intervention of the operator.
