“…Pursuant to the influences of the investigated technological factors, and by means of the prediction, (6) and (7), it is possible to predict the level of vibration parameters of cut material. These equations are applicable within the investigated range of factors for materials with E = 200 GPa and the thickness of up to 15 mm, as it is in the case of stainless steel AISI 309.…”

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.

“…Industry often requires surface treatment of this material. Firstly, the abrasive water jet technology was used to cut the samples from 10 mm thick sheet in order to eliminate thermal effects on the properties of samples [12] to [14]. Dimensions of the test samples were 10 mm × 60 mm × 100 mm (Fig.…”

“…AWJ cutting is a good solution for processing CFRP because of reduced interface temperature, low mechanical loading, better surface integrity, low tool wear, and small cutting forces [3][4][5]. The AWJC uses pressurized water, which acts either by itself at a very high pressure, or in connection with the erosion of the abrasive particles, added into the water jet [6][7].…”

Abstract. The paper presents a preliminary experimental study on processing composite materials (CFRP) using abrasive water jet cutting (AWJC) process, analysing the possibilities of occurrence of material delamination. AWJC is a proper solution for cutting CFRP because of reduced interface temperature, high flexibility, low mechanical loading and reduced cutting forces. Cutting CFRP using AWJC involves several challenges like material delamination due to the high velocity impact of the jet. To understand the delamination, three experimental tests were made: in the first test the cutting and the drilling was made with high water pressure (350 MPa), in the second test the cutting was made with high water pressure and for drilling was used low water pressure (200 MPa) and in last test a pre-drilled hole was used. Within those experiments was observed the CFRP delamination appears just during the drilling, not during the cutting. By decreasing the water jet pressure, the jet energy is decreased and in this way the delamination decrease.
