Enhanced manufacture technology based on emission reduction and carbon reduction in cutting and grinding

Cutting fluid has the effect of reducing cutting force, cutting temperature, improving tool life, etc., which has been widely used in traditional machining.According to statistics, the global annual consumption of cutting fluid is more than 4 million tons.However, with the improvement of carbon reduction and emission reduction requirements, cutting fluids have been unable to meet the future requirements of green manufacturing and sustainable manufacturing due to the problems of unfriendly environment and non-renewable energy.Currently, green and sustainable manufacturing has become a hot topic in the manufacturing industry.Emerging sustainable technologies (e.g., dry condition, minimum quantity lubrication) have been increasingly reported and preliminarily validated.However, there are some limitations under various conditions (e.g., grinding, cutting, milling) and application areas (e.g., aerospace and automotive).Therefore, more attention should be focused on improving machining performance (e.g., reduced energy consumption, improved efficiency and quality, suppression of machining defects) as well as understanding unknown mechanisms (e.g., atomization, penetration, film formation, and thermal stability of the bio-lubricant) by combining existing green and assistive technologies (e.g., ultrasonic vibration-assisted and nanoenhanced bio-lubricants), which can provide theoretical and technical support for the machining of key components in aerospace, rail transportation, automotive, marine, semiconductor, and other fields and accelerate the application of related technologies.On this basis, the authors' team has planned a special issue entitled "Enhanced manufacture technology based on emission reduction and carbon reduction in cutting and grinding," which aims to solve the problems of unclear mechanism of multi-field empowerment-assisted machining cutting and grinding, lack of lubricant atomization, penetration, film formation and thermal destabilization mechanism, and bottlenecks of insufficient sustainable manufacturing strategy.
