PLASMA ARC CUTTING COST

In the machine manufacturing industries, cost estimation and costing are critical. In order to obtain maximum of technical and economical efficiency, in these cases, very important is to estimate the production costs and the production rates. Knowledge of investment and operating costs represents a base for investment in plasma arc cutting machine. For different plasma arc cutting machines typical investment costs and operating costs depend from the power of the plasma cutting machine and important system components. Knowledge of a plasma arc cutting system's investment and operating costs should form the basis for evaluating its profitability. The high investment and operating costs, compared to conventional methods, must be justified according to economic criteria with corresponding financial advantages. In this paper, a mathematical model for determining the cost of plasma arc cutting machining is presented.
