Vibrationbased analysis is the most commonly used technique to monitor the condition of gearboxes. Accurate classifiion of these vibration signals collected from gearbox is helpful for the gearbox fault diagnosis. In recent years, deep neural networks are becoming a promising tool for fault characteristic mining and intelligent diagnosis of rotating machinery with massive data.
· Vibration exposure direction is also important and is measured in defined directions. Vibration frequencies and duration of exposure are also determined. How hard a person grips a tool affects the amount of vibrational energy entering the hands; therefore, handgrip force is another important factor in the exposure assessment.

Vibration analysis is a process of looking for anomalies and monitoring change from the established vibration signature of a system. The vibration of any object in motion is characterized by variations of amplitude, intensity, and frequency. These vibration signatures can be correlated to physical phenomena, making it possible to use vibration data to gain insights into the health of equipment ...
· 1. Introduction. Ultrasonic vibration has been applied in various machining processes including drilling,, turning, and milling .Ultrasonic vibrationassisted milling is one of the advanced nonconventional milling process in order to achieve higher precision, better surface quality, and longer tool life, while retaining the material removal rate at desired level.
· Milling experiments were carried out with an end mill and with five different insert geometries at various cutting conditions. Acceleration signals were sampled from the spindle head of the milling machine. The algorithm for signal processing, computation of the Power Spectral Density, PSD spectrums and the Root Mean Square, RMS values was created in Matlab using the theoretical .
