Energy-saving operation method, evaluation method, device and system in the machining stage of CNC machine tools

Abstract

The invention discloses a numerical control machine tool processing stage energy conservation operation method, an evaluation method, a device and a system. Energy conservation of the numerical control machine tool in the processing stage is realized through stopping and starting an energy consumption part of the numerical control machine tool in an empty cutting state. The method comprises the following steps: operation information of the numerical control machine tool and parts is acquired based on NC code analysis, wherein the operation information of the numerical control machine tool and the parts is operation states of the numerical control machine tool and the parts and corresponding time periods, the operation state of the numerical control machine tool mainly refers to the operation state in the processing stage, and the time period corresponding to the empty cutting state is an energy conservation time period in need of energy conservation, the operation state of the parts of the numerical control machine tool mainly comprises the operation state of an energy consumption part controlled by a PLC; and as for each energy conservation time period, whether the sum of the stopping time and the starting time of the energy consumption part in each energy conservation time period is smaller than the energy conservation time period is judged, and if yes, the energy consumption part is controlled to be temporarily stopped in the corresponding energy conservation time period.

Description

technical field [0001] The invention relates to the fields of energy consumption in machinery manufacturing industry, numerical control machine tools, etc., and in particular to an energy-saving operation method, evaluation method, device and system in the processing stage during the operation of numerical control machine tools. Background technique [0002] Energy saving and emission reduction in the manufacturing industry is an important way for sustainable development. CNC machine tools are an important part of energy-consuming equipment in the manufacturing industry. As the largest manufacturing country in the world, my country has the largest number of CNC machine tools in the world. Its energy consumption is huge but its energy utilization rate is low. Reducing the energy consumption of CNC machine tools is an effective way to achieve energy saving and emission reduction in our country. During the operation of CNC machine tools, due to factors such as processing waiti...
