Numerical control machine tool control method based on energy consumption optimization and numerical control machine tool

Abstract

The invention discloses a numerical control machine tool control method based on energy consumption optimization. The method comprises the following steps that 1, a storage stack, a communication network and a peripheral module of a numerical control machine tool are initialized, the effectiveness of the storage stack is verified, the maximum value of the bus communication rate in the communication network is set as an Ethernet bus cycle period, and the energy consumption interval of current main shaft cutting is read; 2, the energy consumption state of main shaft cutting is monitored in realtime, and information is recorded, wherein the information comprises a cutting thermal power error, additional power for performing compensation execution on the thermal power error and the temperature and humidity at the corresponding moment; and 3, the recorded information is input into a pre-constructed decision table, all power compensation schemes are generated with the energy consumption interval of current main shaft cutting as the constraint condition, the feeding rate of the numerical control machine tool is controlled, the temperature and humidity are adjusted, and therefore the power consumption is minimum.

Description

technical field [0001] The invention relates to the field of automation control, in particular to a control method of a numerically controlled machine tool based on energy consumption optimization and the numerically controlled machine tool. Background technique [0002] Manufacturing has become one of the main sources of energy consumption and carbon emissions today. Research by the International Energy Agency shows that nearly 1 / 3 of global energy consumption and 40% of carbon dioxide emissions are attributed to manufacturing. A study by the Massachusetts Institute of Technology shows that the carbon dioxide emissions produced by a CNC machine tool running for one year are equivalent to the annual carbon dioxide emissions of 61 SUVs. As the key equipment in the manufacturing industry, CNC machine tools have significant energy consumption and carbon emissions. Therefore, the study of energy consumption prediction and energy-saving technology of CNC machine tools plays a ve...

The cutting power of the constant cutting rate process is also a stable value, while the power of the variable cutting rate process changes dynamically with time, which is more complicated than the power characteristic of the constant cutting rate process

However, there are few reports on cutting power and energy consumption in the process of variable cutting rate.
