In this paper research elements regarding the effect of water pressure variation on cut surfaces quality are presented in the field of abrasive water jet cutting of materials hard to process by machining such as austenitic stainless steels, in this case with a thickness of 20 mm. Selection of the optimal cutting process based on technical and economic criteria takes into consideration the type and thickness of the targeted material and also the physical and geometrical quality requirements. The present paper contains experimental research results regarding abrasive water jet cutting of austenitic stainless steel EN 1.4306 (ASTM 304 L) at different values of water pressure. The abrasive material used is Garnet with particle granulation 80 Mesh. By making roughness measurements and hardness examinations of the cut surface an evaluation will be made of the surface quality defining the optimal pressure values.

Modern materials cutting operations are traditionally part of the research priorities and also in the production activities of ISIM Timișoara. In the last decade, within the institute, a special emphasis was placed on the development of the abrasive water jet cutting process as well as on implementing the research results obtained into industrial activities. The paper presents own achievements and contributions of ISIM to the development of the abrasive water jet cutting process in the following directions: cutting technologies for materials with different characteristics, innovative new patentable solutions regarding the cutting process respectively important modules in the composition of the water jet cutting equipment, ways to recycle used abrasive waste, solutions to streamline the process. The proposed solutions have been verified with good results in industrial applications, or have been proposed for analysis and development together with specialists in the field from important research units.

This article deals with measurement of the thermal gradient on material during abrasive water jet cutting. The temperature was measured by thermocamera before the technological process started, during the abrasive water jet cutting process technology, and just after the cutting process. We performed measurements on several types of materials. We calculated the approximate amount of energy during the abrasive water jet cutting process technology that changes into thermoenergy, which is the current water pressure drained in a catcher tank.

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.
