In order to understand the energy consumption level of the machinery manufacturing industry and propose an energy efficiency evaluation method with strong operability and good applicability, based on the previous research results such as the energy efficiency model of the machining workshop and the evaluation index system, a set of general machining system energy is proposed. Efficiency evaluation method framework and its key technologies. The method includes 6 steps of energy efficiency evaluation boundary division, energy efficiency evaluation index determination, energy efficiency data collection, energy efficiency evaluation tool selection, energy efficiency evaluation result output and energy efficiency level analysis. Based on Practicality This paper proposes a set of energy efficiency evaluation indicators for machining systems at the process (equipment) level and the workshop system level. The system reflects the energy efficiency of the workpiece machining process at the micro level and the energy efficiency of the unit output of the product at the macro level. Starting from this, a structured and object-oriented energy efficiency data acquisition method is given. The validity of the energy efficiency evaluation method is verified through a case study. The operability of energy efficiency evaluation.
The energy consumption of mechanical processing equipment (process) is the main body of the energy consumption of the mechanical processing system, and its energy consumption process and energy efficiency evaluation are also the most complex. It is generally believed that the energy consumption of mechanical processing equipment is divided into fixed energy consumption and variable energy consumption, and the proportion of effective energy to the total energy of the equipment may be very low. Moreover, different machining parameters and tool paths will affect the energy consumption of the machining process, and the energy consumption characteristics of different machining processes will present different trends. The influence of milling machine processing parameters (such as tool cutting angle) on the specific cutting energy was studied, and the cutting width and cutting depth with good energy efficiency were obtained.
