Technological and Sustainability Implications of Dry, Near-Dry, and Wet Turning of Ti-6Al-4V Alloy
Maria Giulia Faga,Paolo C. Priarone,Matteo Robiglio,Luca Settineri,Vincenzo Tebaldo 한국정밀공학회 2017 International Journal of Precision Engineering and Vol.4 No.2
Titanium-based alloys are commonly applied in high-performing structural components. Their machinability could be penalized by severe tool wear and poor surface quality. As a result, cutting fluids are widely used to improve the production rate without negatively affecting the machined surface integrity and the tool life. The experimental research activities presented in this paper are focusing on the effects of dry and near-dry cutting conditions on machining process performance when turning Ti-6Al-4V. Minimum Quantity Cooling/Lubrication systems have been exploited to supply low cutting fluid volumes to the cutting area in the form of a precision-metered droplets mist. The conventional flood cooling (i.e., wet cutting) has been assumed as benchmark. Results are discussed with respect to tool wear/life, cutting forces, process power demand, surface quality, lubricoolant consumption, and human health hazards. All the main factors of influence are highlighted, and guidelines for identifying the trade-off between the minimization of environmental impact and the enhancement of process productivity are proposed.

The Three-Bite Technique: A Novel Method of Dog Ear Correction
Jaber, Omar,Vischio, Marta,Faga, Angela,Nicoletti, Giovanni Korean Society of Plastic and Reconstructive Surge 2015 Archives of Plastic Surgery Vol.42 No.2
The closure of any circular or asymmetric wound can result in puckering or an excess of tissue known as a 'dog ear'. Understanding the mechanism of dog ear formation is a fundamental requirement necessary to facilitate an appropriate treatment. Many solutions have been reported in the literature, but in all cases, the correction entails the extension of the scar and the sacrifice of the dermal plexus. Here, we propose a novel technique of dog ear correction by using a three-bite suture that sequentially pierces the deep fascial plane and each dog ear's margin, thus allowing for flattening the dog ear by anchoring the over-projecting tissue to the deep plane. The three-bite technique proved to be a fast, easy, and versatile method of immediate dog ear correction without extending the scar, while maintaining a full and complete local skin blood supply.
