Ultrasonic processes machining

The assembly process described above using the press is not necessary in case non-traditional or plastic materials are to be used. For such materials, the cut panel takes a different path towards an ultrasonic welding machine for Inserting a joining strip that will connect the panel to the floor and roof systems In the main assembly line. 

A comprehensive program that includes predictive maintenance techniques to monitor and analyze critical machines, equipment, and systems in a typical plant. Techniques include vibration analysis, ultrasonics, thermography, tribology, process monitoring, visual inspection, and other non-destructive analysis methods. 

Unlike vibration monitoring, ultrasonics monitors the higher frequencies, i.e. ultrasound, produced by unique dynamics in process systems or machines. The normal monitoring range for vibration analysis is from less than 1 Hertz to 20,000 Hertz. Ultrasonics techniques monitor the frequency range between 20,000 and 100 kHz. 

A number of applications of power ultrasound are to be found in heavy industry both in metalworking and processing [17]. The machining of modem materials requires tools that can deal with unusual properties, complex shapes of work-pieces, and accuracy in working. Basic ultrasonic machining processes become of importance when dealing with carbides, stainless steels, ceramics and glass. Four main types of application are of industrial relevance ...

The compression of a powder is a complex process that is usually affected by different kinds of problems. These problems have been widely investigated and mainly concern the volume reduction and the development of a strength between the particles of the powder sufficient to ensure tablet integrity [82], The application of ultrasonic energy shows a great ability to reduce and even avoid these problems [83], Ultrasound refers to mechanical waves with a frequency above 18 kHz (the approximate limit of the human ear). In an ultrasound compression machine, this vibration is obtained by means of a piezoelectric material (typically ceramics) that acts as a transducer of alternate electric energy of different frequencies in mechanical energy. An acoustic coupler, or booster, in contact with the transducer increases the amplitude of the vibration before it is transmitted (usually in combination with mechanical pressure) to the material to be compressed.

Compared to other micromachining processes such as micro-EDM, micro-USM (Ultrasonic machining), micro-LBM (laser beam machining), and tool-based micromachining, the initial setup as well as mnning cost of EMM is lesser.
