This paper presents a study conducted to examine the effect of cutting parameters, namely standoff distance, nozzle traverse speed (TS), abrasive flow rate (AFR), and material type on cutting performance for two types of marble workpieces, Carrara white and Indian green. Statistical analysis was undertaken to assess the influence of the cutting parameters on the process performances in terms of surface roughness, surface waviness, and Kerf taper ratio. The results showed that the TS and material type were the most significant factors that affected surface roughness and Kerf taper ratio. Also, although AFR was found to have significant effect on surface waviness, it had no noticeable influence on surface roughness nor Kerf taper ratio.

“…The levels of these parameters are presented in Table 3. The levels of the traverse speed were chosen based on previous experiments done by others [6][7][8][9][10][11][12][13] and by the authors [14] for the type of material which was tested. The levels for the other parameters were chosen based on some practical considerations about the use of Hardox steels in the real workshop of the company which is partner in this research project.…”

“…The main technological parameters of influence on the process of AWJ which are considered by the comprehensive researches until present day [3][4][5][6][7][8][9][10][11][12][13] are: the water pressure, the traverse speed, the abrasive flow rate and the distance between the nozzle and the surface of the material to be cut, usually called standoff distance. The water pressure directly influences the process productivity and costs and almost all researches agree that it is better to use the maximum value given by the equipment.…”

“…There is a larger number of parameters which have an influence on the quality and cost of the process [5]. In the last decade there were published several research studies on AWJ, focusing mainly on the surface roughness, the kerf formation and the influence of the traverse speed on those parameters [6][7][8][9][10][11][12][13]. But each research analysed one type of material and the results have the validity for that type of material.…”

An experimental study on the dimensional accuracy of holes made by abrasive waterjet machining of Hardox steels

Abstract. The manufacturing process of special steels like Hardox is usually difficult. Abrasive waterjet cutting (AWJ) is one of the machining processes which can be used in this case, with good results, as proved in previous research of the authors. This paper presents an experimental study on the influence of the AWJ main process parameters to the dimensional accuracy of holes manufactured in Hardox steels. The experiments were conducted using a L8(2 4 ) fractional factorial design matrix considering four parameters: the traverse speed, the part thickness, the hole dimension and the material type. Based on the measurement of the dimensions of the holes, the influence of those parameters was revealed and analyzed. The manufacturing time was also registered, as this parameter directly influences the production cost. Further research aims developing a mathematical model which will be a useful tool in workshop process planning.

Reduction of dimensional variability of pieces, resulted in AWJ process, using robust design method

Abstract. Dimensional variability arises in AWJ system from uncontrolled factors intervention or due to the variability of input signals considered fixed or due to interactions of the input signals with unexpected effects, leading to deterioration of unpredictable outcome. Number of noise factors, negatively influence the results registered, dispersion of the result values is directly proportional to the number and their effect. Stochastic influence and his unpredictable nature determine a thorough research of the hydroabrasive process. The research refers to the study of dimensional variability for different configurations of hydroabrasive liquid pressure, abrasive type and traverse velocity. This is achieved by performing the experiments statistically processed by combining of control parameters, which allow favorable conclusions on reducing variability results and on optimizing the entire process of hydroabrasive machining.
