Analysis and Experiment of Multi Energy Field Composite Processing Mechanism of SiCp/Al Composite Materials
Effectively combining traditional grinding processing with special processing methods such as rotary ultrasonic and electrical machining to achieve effective processing of SiCp/Al composite materials.Study the mechanism of rotary ultrasonic mechanical electrolytic composite machining,analyze the effect of multi energy field parameters,explore machining efficiency and surface quality,and establish mathematical models.Design and develop a rotating ultrasonic composite multi energy field machining system.Using a Φ4 mm electrode and 4 V electrolytic voltage,the SiCp/Al composites with 30%silicon carbide content were subjected to rotational ultrasonic and one-dimensional and two-dimensional ultrasonic multi-field machining tests.The results showed that the ultrasonic multi-energy machining could significantly reduce the surface roughness of a single rotary ultrasonic machining,and process a smoother plane and micro-structure.At the same time,compared with one-dimensional machining,the efficiency of two-dimensional rotary ultrasonic composite machining can be increased by more than 20%,the machining accuracy can reach 0.01 mm,and the surface roughness is Ra1.6 μm.The ultrasonic multi-energy field processing process is stable and has significant multi-technology compound advantages.
