Enhanced Heat Transfer Technology Based on Emission Reduction and Carbon Reduction in Cutting and Grinding

Huge carbon emissions in machining process, which characterized by high energy consumption and usage of non-renewable resources, is becoming an obsession in the past decades. In the face of the international strategy of carbon peak, it is imperative to eliminate the usage of mineral cutting fluids and reduce energy consumption and carbon emissions by green cutting/grinding technologies, such as dry cutting, minimum quantity lubrication(MQL). However, higher heat output and temperature rise is caused in cutting zone, which leads to serious tool wear and deterioration of workpiece surface quality. To enhance the heat transfer performance and reduce carbon emission and energy consumption in the manufacturing process simultaneously, the exploration of enhanced heat transfer technology based on emission reduction and carbon reduction in cutting and grinding is a research hotspot at present. This Special Issue report on the above advanced technologies and research progress, including tool design and preparation, green lubricant preparation, multi-energy field assistance technologies, and processing mechanisms for difficult-to-cutting materials.
