...-objective Taguchi technique, analysis of variance (ANOVA) and regression analysis. Design/methodology/approach The bronze-based composite materials containing 5, 10 and 15 Wt.% fly ashes were prepared by using spark plasma sintering carried out under a pressure of 35 MPa, at 750, 800 and 850 °C for 3...

... the ANOVA. Regression analysis was used to derive the predictive equations for both friction coefficient and wear rate. Findings It was found that the most significant parameter that affects the COF is the weight composition, while for the wear rate, it is the operating temperature. The proposed...

... was to establish a model using multiple regression analysis between spindle speed, drilling depth and feed rate with the drill bit temperature and thrust force in an AISI 1040 steel material. Findings Statistical results show that drill bit temperature was significantly influenced (at 95 percent confidence...

... regression analysis (MRA). Design/methodology/approach This paper presents a new thermo‐mechanical model to predict the tribological behaviour of the composite PEEK‐CF30/steel pair, in dry sliding, using MRA. A plan of experiments was performed on a pin‐on‐disc machine PLINT TE67HT^®...
