According to the method, high-precision and high-sensitivity high-temperature infrared thermal imaging equipment is used for collecting the actual temperature of a tool and a peripheral area in the machining process, a thermal analysis mode is adopted, an ideal working condition temperature is obtained by combining a workpiece three-dimensional structure diagram, a technological parameter table and a tool parameter table, the difference value between the ideal working condition temperature and the actual temperature serves as guidance, the feeding speed of a cutter, the rotating speed of a workpiece and the using amount of cooling liquid in the machining process are adjusted, so that the machining temperature is controlled within an ideal working condition range, cutter abrasion is reduced, and the service life of the cutter is prolonged; in addition, due to the proper control of temperature, the damage to the material of the machined workpiece is greatly reduced, the workpiece machining optimization of the numerical control machine tool is achieved, and finally machining energy consumption is reduced.

Description

technical field [0001] The invention belongs to the field of optimized processing of workpieces, and more specifically relates to a method for realizing optimized processing of workpieces by using high-temperature infrared thermal imaging technology. Background technique [0002] At present, the energy consumption of the manufacturing industry has always been the main aspect of energy consumption, and the energy consumption of the machining system has always been in a dominant position in terms of energy consumption. As environmental issues become more prominent, reducing energy consumption is an important task for all manufacturing industries. The first aspect of reducing energy consumption is to monitor and collect energy consumption in real time, and only after evaluating the energy consumption data can specific energy reduction strategies be formulated. [0003] In the process of CNC machine tool processing, the temperature of different workpiece materials at the positi...

Problems solved by technology

[0003] In the process of CNC machine tool processing, the temperature of different workpiece materials at the position of the processing area (that is, the contact area between the tool and the workpiece) under different processing technologies (including tool selection, cutting, feed speed, etc.) is very different, and different The temperature at the contact point has different effects on the tool and energy consumption. If the processing speed is fast, the energy consumption is relatively low. However, when the processing speed is too fast, it is easy to cause greater damage to the tool, resulting in the tool being scrapped too quickly, thus increasing the number of replacement tools. and equipment maintenance costs, and increased production energy consumption
