Laboratory studies to investigate the relationship between energy consumption of diamond wire cutting machine with physical and mechanical properties of carbonate rocks

One of the criterions for evaluating the cutting of building stone using the diamond wire cutting system is the energy consumption of the cutting wire machine. In this study, in order to evaluate the amount of energy consumed in the cutting process, a laboratory diamond cutting wire system was designed and built with the ability to change and stabilize the operational and tooling parameters of cutting, including linear velocity, backward pulling speed and angle of impact of diamond wire. In order to determine the relationship between the physical and mechanical properties of the stone with the energy consumption of the cutting machine, 6 different samples of travertine were prepared from the mines of East and West Azerbaijan, Isfahan, Yazd and Markazi provinces and The values of physical and mechanical properties including density, porosity, water absorption, uniaxial compressive strength, tensile strength and the speed of ultrasonic waves passed through them were measured in the laboratory. Then, by cutting cubic blocks of the samples with the laboratory diamond cutting wire system, the energy consumption of the device in different situations of the angle of the wire with the sample was recorded. Using regression and univariate fitting, the relationship between each of the rock properties and the specific cutting energy with respect to linear, logarithmic, power and exponential functions was investigated. The results showed that the best value for the angle at which the wire hits the specimen, at which the lowest specific energy consumption is recorded, was 15 degrees.
