Machine learning based hierarchy of causative variables for tool failure in friction stir welding

Acta Materialia, 2020
Since friction stir welding tools fail in service under various mechanisms, it is difficult to mitigate tool failure based on mechanistic understanding alone.

Surgical Tool Failure Analyses

Journal of Failure Analysis and Prevention, 2013
Abstract Several surgical tool failures were analyzed to understand why they occur and how to prevent them. The study included drills, catheters, and needles subjected to the rigors of biomedical applications such as corrosive environments, high stresses, sterilization, and improper cleaning procedures.

Joint strength and failure studies of dissimilar AA6061-AA7075 friction stir welds: Effects of tool pin, process parameters and preheating

Engineering Failure Analysis, 2019
The present study aims at bracketing the effect of tool pin geometry, process parameters e.g. tool rotational speed, feed rate, and use of additional heat source (preheating) during dissimilar friction stir welding (FSW) between 6061-T6 and 7075-T651 ...

Progressive wear based tool failure analysis during dry and MQL assisted sustainable micro-milling

International Journal of Mechanical Sciences, 2021
Micro-milling tools suffer high wear rate and early edge-chipping owing to their small sizes. Mechanism of various wear modes of a coated tool with the progression of micro-milling along with the conditions for their onset was not systematically explored

Analytical modeling of tool failure boundary map in milling titanium alloy

Proceedings of the Institution of mechanical engineers. Part B, journal of engineering manufacture, 2021
As a typical aerospace difficult-to-machine material, tool failure in milling titanium alloy Ti6Al4V will reduce the stability of the milling process and affect the surface quality of the workpiece.

Heart Failure Tools

Critical Pathways in Cardiology: A Journal of Evidence-Based Medicine, 2009
Our heart failure team was part of the Accelerating Best Care in Pennsylvania program through a grant by our State Representative, Todd Eachus. Our team met weekly and identified high leverage points that needed to be addressed-one being that of discharge instructions. We also identified the need for standing order sets for heart failure admissions. We

Tool failure detector

The Journal of the Acoustical Society of America, 1987
A failure detector detects breakage in a machine tool cutting element, such as a drill bit, by use of a accelerometer supported against a workpiece being operated on by the cutting element. Vibrations are induced in the workpiece by the cutting operation, the vibrations having spectral components in the audio frequency range which are characteristic of
