Design Of Atomizing Nozzle And Experimental Research Of The Cutting Fluid Of Oils On Water

In traditional metal cutting processing, it takes a lot of cooling and lubricating liquid to prolong tool life, but only a small amount of cutting fluid in machining process can have the effect of cooling and lubrication, it causes a lot of waste. Besides,most of the cutting fluid is dangerous and will harm to workers health and environment. Therefore, green cutting technology has become the focus in the field of mechanical manufacturing in twenty-first Century.This paper introduces the research status, the principle of cooling and lubrication and the characteristics of several new green cutting technology, and mainly introduced the oils-on-water(OoW)cutting technology in these respects.Through the analysis and study of the atomization principle and several atomizing nozzle,the basic structure is designed and the main parameters are calculated of the Oo W atomizing nozzle.In three different cooling and lubricating conditions, through the single factor experiment and multi-factor orthogonal experimental, it quantitative analysis and comparison the impact of cutting force and surface roughness, through the orthogonal experiment of the Oo W cutting conditions, the key factors affecting the cutting force and surface roughness are determined, and the optimal cutting parameters are determined.Through multiple linear regression method to establish the mathematical model between the independent variables(cutting speed, feed and cutting depth) and dependent variables(cutting force, surface roughness), there is a significant relationship between independent variables and dependent variables through significant tests.The results show that it has obvious advantage of OoW cutting fluid through multiple experiments, it can effectively reduce the cutting force and the surface roughness, and as a new type of green cutting technology, has large research value and broad market.
