Ultrasonic Machining
Ultrasonic assisted machining is a recently-developed technique, in which high-frequency (> 20 kHz) vibration is superimposed onto the movement of a standard drill bit in the axial direction, providing advantages including reduced drilling forces (reduction often in excess of 80%) and improved quality of drilled holes when compared to conventional drilling. Ultrasonic assisted drilling also achieves a reduction in entry and exit delamination size, but not in the expected proportion considering the observed reduction of drilling forces. A different mechanical process to that in conventional drilling may be driving the delamination in Ultrasonic assisted drilling, for example dynamic or thermal effects in addition to thrust and torque loads.
The aim of this project is to achieve a mechanical understanding of the process that drives delamination during Ultrasonic assisted drilling and to implement it in an analytical model and numerical tools with predictive ability. These can then be used to enhance Ultrasonic assisted drilling to minimise delamination and to predict the performance of hybrid joints with Ultrasonic assisted drilling-induced damage.
Principle:
Ultrasonic machining offers a unique blend of capabilities, quality and material compatibility for the machining of engineered ceramics and advanced technical materials. The process is versatile, offering flexibility to meet a wide range of design requirements, and yields high-quality parts with little or no subsurface damage and no heat-affected zone. These benefits make it a valuable resource for the scientists, engineers and designers who are developing tomorrow’s advanced technologies.
An added benefit is that parts machined ultrasonically often perform better in downstream machining processes than do parts machined using more conventional machining methods. The improved performance can result in economic advantages from higher yields, lower scrap and operating costs, and improved efficiencies

During ultrasonic drilling, the material is removed by micro-grinding or abrasive particle erosion. The tool oscillates at a frequency of approximately 20 kHz by a piezoelectric sensor and an electric oscillator. The tool forces the abrasive grit to normally impact the work surface in the gap between the tool and the workpiece to machine the work surface.

Customized Knife Handle Ultrasonic Vibration Spindle With Power Control
Ultrasonic machining (UM or USM) is a non-thermal, non-chemical and non-electrical process that keeps the chemical composition, material microstructure and physical properties of the workpiece constant. Sometimes referred to as ultrasonic impact grinding (UIG) or vibratory cutting, this process can be used to create a variety of complex features in advanced materials.

Ultrasonic milling has proven to be an effective technique for improving titanium, aluminum and stainless steel workability. Under the action of ultrasonic milling, it has more advantage than the traditional milling. In contrast to the effect of ultrasonic machining aluminum, steel, stainless steel, titanium four metallic materials.Improved surface quality of the most prominent is the titanium and aluminum, can improve the cutting ability of the most prominent is the stainless steel, the quality of the workpiece side is the most significant improvement in steel.
