Energy consumption when processing the steel workpieces with fast-cutting drills made from different chemical compounds

Energy saving at industrial enterprises is one of the most crucial problems nowadays, since the power cost is constantly increasing. Among the expenditures for products manufacturing including the expenses for raw stores and materials, fuel and energy, earned income, operational and other costs the energy constituent has a considerable proportion. The article considers energy expenditure for drilling holes in the constructional steel with the high-speed steel drills of different marks. Under the assumptions made for the torque and drilling axial force independence from the drill cutting unit chemical composition it has been established that the application of the constructional steel drills of different marks preconditions the differences in energy consumption. It determines the need for the judicious selection of the tooling material when solving the problem of optimization in terms of energy saving.
