“…Four key parameters were considered as the input variables namely; stand-off distance (S OD ), abrasive mass flow (A MF ), feed rate (F R ) and water pressure (W P ). The selection of these parameters was based on the rationale that their impact has been noted as significant on surface roughness in the reported literature [15][16][17][18]20]. Preliminary trials were also performed for selecting the appropriate levels of the selected control variables.…”

“…Considerable research has been conducted in the past to understand the mechanism and to investigate the parametric effects in AWJM with respect to surface roughness. For instance, Babu et al [15] have found that water pressure (W P ) is the most contributing factor for R a during AWJM of brass-360. Uthayakumar et al [16] also reported that W P was the prominent factor affecting the surface morphology of Ni-based super alloy cut by abrasive water jet.…”

Clad composites have emerged as a suitable choice to augment the industrial needs due to having a combination of different properties. The accurate cutting is challenging due to the heterogeneous nature of the composite. Conventionally, thermal cutting (plasma/gas) techniques are commonly employed which provide poor cut quality, deeper heat affected zones and demand additional finishing operations. Therefore, this research evaluates the potential of abrasive water jet cutting (AWJC) as a proficient substitute for the cutting of stainless-clad-steel composite in terms of surface quality. However, it is difficult to produce a similar level of surface finish at both the layers because the constituent layers have different mechanical properties. The effect and significance of four important AWJC parameters on cut quality are examined through statistical analyses. Optical and scanning electron microscopic analyses are further provided as evidence of the reported results. Optimal settings are also developed using a weighted signal-to-noise ratio technique which can provide minimal roughness at each layer. Moreover, using the optimal settings, a similar level of surface finish has been achieved for both the layers with a difference of just 0.03 µm between the constituent layers.

2015):Method for modifying convective heat transfer coefficients used in the thermal simulation of a feed drive system based on the response surface methodology, Numerical Heat Transfer, Part A: ApplicationsTo link to this article: http://dx. ABSTRACTThis paper presents a method based on response surface methodology (RSM) to calculate the convective heat transfer coefficients (CHTCs) of a feed drive system. First, the temperature values at thermal-critical points and ball screw thermal elongation of a feed drive system were obtained by experimental and finite element (FE) methods. Second, the relationship between the CHTCs and simulated temperature values was established using RSM, and the CHTCs were calculated using the designed 25 tests. Finally, the effectiveness of the proposed method was proved using steady-state and transient-state simulation of the feed drive system.

“…With respect to the different fluid contents, water jet cutting can be divided into pure water jet cutting (WJ) and abrasive water jet cutting (AWJ). Compared to traditional cutting technologies, AWJ offers the following advantages: negligible thermal effects, small machining force, good working conditions and environment, long tool life, high flexibility, and high machining versatility (Yue et al 2014). Currently, AWJ is widely used in various industries.…”

The effects of pressure, feed rate, and abrasive mass flow rate on surface roughness were investigated during abrasive water cutting of recombinant bamboo. Two different thicknesses (10 mm and 15 mm) of recombinant bamboo were cut in the longitudinal and transversal directions by abrasive water jet. All experiments were arranged using response surface methodology. The parameter Ra was selected to represent the surface roughness. The value of Ra increased with an increase in feed rate and abrasive mass flow rate, but decreased with an increase in pressure. The surface roughness was lower when cutting the fiber longitudinally than when cutting transversally.
