PARTIAL EFFECT OF CUTTING PARAMETERS ON ENGAGED POWER AND ENERGY CONSUMPTION: THE CASE OF EXTERNAL TURNING OF AN AISI1045 STEEL

Abstract

With the ever-growing interest in energy saving during machining processes, it is important to be able to assess energy consumption for various machining conditions. The paper presents results on measuring of engaged power and energy consumption for external turning of an AISI1045 steel part. A series of experiments were conducted in which the values of cutting speed, depth of cut and feed rate were changed within their selected range. The measurement was performed using an advanced energy sensor that allows detailed monitoring of the engaged power and energy in real time. The measurement results draw out the partial effect of each of the parameters on the increase in the engaged power and the consumed energy. In addition, the measurement results enable the development of a prediction model that can be useful for making the optimal choice of machining parameters regarding energy consumption, especially for the cases of high-volume manufacturing.
