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.

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.

Combining with the electron microscope analysis of the morphology of incision, the mechanism of abrasive water jet cutting metal materials was carried out to explore, for the rational selection of abrasive jet cutting parameters, to extend its application to provide the basis. Study shows that the abrasive water jet cutting metal materials, the material damage mechanism is mainly to yield deformation and failure and shear of grinding damage, grooving formation is mainly caused by falling impact deformation and furrows grinding.
