Abstract: A kind of single inlet swirl atomizer is set to adjust the inlet location and the length of the outlet for an optimization spray angle and uniformity in this literature.Stationary wave theory is used to describe the results of spray quality.Experimental and theoretical analysis show that using property machining process size, single inlet swirl nozzles can achieve the optimized quality of atomization (spray cone angle of 55 °and more, skewness of spray cone center below 5 ° ).

Abstract: In this paper a method of ultrasonic elliptical vibration cutting has been applied to precision boring of micro hole due to its superior performances such as low cutting force, high quality surface finish and long tool life. A transducer with the longitudinal excitation is carried out to machining(boring) micro hole of 1Cr18Ni9Ti workpiece. The cutting force and surface quality are studied in detail.The workpiece with surface roughness of Rz 0.4μm is achieved.The results showed that the ultrasonic elliptical vibration transducer can be applied rationally in micro hole precision boring.

Abstract: The connotative meaning and trend of bionic design and manufacturing was analyzed. A new bioforming technology was presented, which will offer a new way to solve the difficulties in manufacturing of bionic micro-nano structures, and the layout of bioforming technology was also plotted. Several different bioforming technologies targeting typical bionic products were introduced. Compared with traditional manufacturing methods, to machine complicated micro/nano shapes, structures, functional interfaces with bioforming technology has more advantages, which showed that bioforming technologies would have great potential applications in energy-saving, environmental protection, and micro/nano fields.
