I am explaining the background of the birth of semi-dry processing.
The concept of semi-dry processing emerged in response to global warming and environmental pollution issues that began to rise worldwide in the 1990s.
As a result of post-war mass production in the industrial sector, serious environmental pollution, such as air pollution, was brought about in various countries. Consequently, international conferences aimed at addressing these issues began to be held around 1990. This prompted companies worldwide to recognize the necessity of seriously addressing the reduction of pollutants in production and social activities, as well as resource and energy conservation, a commitment that continues to this day.
In the keynote paper of the 1997 CIRP (International Academy for Production Engineering) annual report, the demands from society to the industrial sector were summarized into four points: "advanced high-performance materials," "high productivity," "high precision," and "environmental consideration needs."
At that time, a large amount of cutting oils was used in machining, leading to environmental pollution from waste generated during their lifespan, and 40% to 60% of machine power was consumed in oil supply and circulation.
In response, research was conducted to thoroughly reduce cutting oil, leading to the development of semi-dry processing. The movement towards this "non-waste" economic system continues to this day.
