Ultrasonic assisted grinding process with minimum quantity. Aug 15, 2016 It is observed that in all cases, application of horizontal ultrasonic vibration had led to lower grinding forces, with the reduction in normal force being more prominent. The normal force has reduced from 37% to 61% under different cooling/lubricating conditions.get price

1. I N T R O D U C T I O N AS HAS been explained previously [1-3] grinding time plays a very significant part irt the process of generating self-excited vibration. Initially, if a freshly dressed and balanced wheel is used for grinding, no visible vibration is present. Only after a certain machining time when no dressing operation has been applied self-excited vibration appears and its ...

Ultrasonic machining is a kind of grinding method. It is also called as ultrasonic grinding. The term ultrasonic is used to describe a vibratory wave of frequency above that of the upper frequency limit of the human ear, i.e. generally above 16 KHz. The device for converting any type of energy into ultrasonic waves is ultrasonic transducer.

In this paper, a novel ultrasonic vibration assisted grinding (UVAG) technique was presented for machining hard and brittle linear micro-structured surfaces. The kinematics of the UVAG for micro-structures was first analyzed by considering both the vibration trace and the topological features on the machined surface.
