Investigating the effects of vibration method on ultrasonic-assisted drilling of Al/SiCp metal matrix composites

Preciseness and finished surface quality are the significant factors of final products, especially in a number of drilling processes. Burr is usually considered a negative outcome in assembly procedures. One way to reduce or remove burr and improve surface roughness in metal cutting is to employ ul...
