Application Of Hypothermia In Cold MQL Technology Of Titanium Turning

Manufacturing provides a wealth of products to humans, it is also the raw material extraction, refining, processing produced a large number of industrial "three wastes", causing serious pollution to the environment, leading to environmental degradation and resource depletion is characterized by ecological crisis. So people began to study green manufacturing technology, that is, under the premise of ensuring product features, quality, cost, considering the environmental impact and resource efficiency of modern manufacturing mode. It makes products from the design, manufacture, use and disposal of the entire product life cycle environmental pollution is minimized, so that maximum utilization of resources, the lowest energy consumption.Green cutting technology which is one of the key technologies of green manufacturing, including dry machining, cutting fluid processing biodegradable, low-cut cutting dry machining, machining and cold cold cold cold MQL processing. Because of the performance of increasingly demanding, difficult materials (titanium, etc.) are widely used, the corresponding green cutting technology forward a higher level of low-temperature cold MQL technology.Cutting through the green paper mainly technical analysis, the principle of atomization technology cryogenic cold MQL nozzle atomization field formed the theoretical analysis and finite element atomization field flow analysis; turning of titanium alloy (sub-dry) MQL cutting mechanism research, analyze the causes and course of capillary formation, exploring oil into the channel and the establishment of micro-lubricant film formation process, explaining the reasons for the cutting force can effectively reduce; exclusion with experimental conditions, changes in the experimental The experimental conditions of whether to add a trace lubricants, cutting force is reduced without the oil film in the proof of the existence of the two conditions; derive a theoretical model to reduce cutting force, i.e., a small cutting force model boundary lubrication theory proves.
