In this study, ultrasonic assisted machining (UAM) technique is applied in side-surface milling experiment for glass-ceramic workpiece material. The tungsten carbide cutting-tool with diamond coating is used in conjunction with two kinds of cooling/lubrication mediums such as water-soluble (WS) cutting fluid and minimum quantity lubricant (MQL). Full factorial process parameter combinations on ...

Rotary ultrasonic machining (RUM) is one of the machining processes for advanced ceramics. Edge chipping (or chamfer), commonly observed in RUM of ceramic materials, not only compromises geometric accuracy but also possibly causes an increase in machining cost. In this paper, a three-dimensional finite element analysis (FEA) model is developed to study the effects of three parameters (cutting d...

Ti6Al4V alloys are difficult-to-cut materials that have extensive applications in the automotive and aerospace industry. A great deal of effort has been made to develop and improve the machining operations of Ti6Al4V alloys. This paper presents an experimental study that systematically analyzes the effects of the machining conditions (ultrasonic power, feed rate, spindle speed, and tool diamete...

In recent years, advanced materials with unique metallurgical properties such as super alloys, composites and ceramics have been developed to meet the demands of extreme applications. While these materials are harder, tougher, less heat sensitive and more resistant to corrosion and fatigue, they are also difficult to machine. Advanced materials are being widely used these days not only in the a...

The purpose of the present investigation is to compare the statistically controlled machining solution of titanium alloys using ultrasonic machining (USM). In this study, the previously developed Taguchi model for USM of titanium and its alloys has been investigated and compared. Relationships between the material removal rate, tool wear rate, surface roughness and other controllable machining ...

Machining-induced edge chipping damage represents a common challenge in ceramic applications. This paper reports on responses of zirconia materials with porous and dense microstructures to induced conventional ultrasonic vibration-assisted diamond machining. The machining-induced was evaluated using optical scanning electron microscopies. results show that produced these processes associated br...
