A novel failure mode and effect analysis model for machine tool risk analysis
Reliability Engineering & System Safety, 2019Increasing the reliability of machine tools and reducing possible risks during the manufacturing process is crucial for the future of industry. The failure mode and effects analysis (FMEA) method is reliant upon the experience of experts to determine the

Characteristics of the failure of tool materials
Metal Science and Heat Treatment, 1994Tool materials for metal cutting tools, with hardness exceeding 62 HRC as a rule, are destroyed, in distinction to most structural steels and alloys, by brittle failure without any noticeable macroscopic deformation. The article examines the characteristics of such failure.

Investigation of the tool-rock interaction using Drucker-Prager failure criterion
Journal of Petroleum Science and Engineering, 2019Mechanical rock breaking in different forms have found wide applications in the mining and civil engineering industry such as drilling, tunnelling and grinding. A detailed understanding of the tool-rock interaction is essential to achieve high efficiency

WebSee: A Tool for Debugging HTML Presentation Failures
2015 IEEE 8th International Conference on Software Testing, Verification and Validation (ICST), 2015Presentation failures in a website can negatively impact end users' perception of the quality of the website, the services it delivers, and the branding a company is trying to achieve. Presentation failures can occur easily in modern web applications because of the highly complex and dynamic nature of the HTML, CSS, and JavaScript that define a web ...

Failure Analysis in Tool Steels
2008AbstractThis chapter focuses on the failure aspects of tool steels. The discussion covers the classification, chemical composition, main characteristics, and several failures of tool steels and their relation to heat treatment. The tool steels covered are hot work, cold work, plastic mold, and high-speed tool steels.

Evaluation of an Inpatient Heart Failure Screening Tool
Journal of Nursing Care Quality, 2014Heart failure is increasing in incidence, prevalence, and mortality. The purpose of this study was to test the predictive accuracy of a screening tool to identify inpatients with heart failure. The tool demonstrated statistical significance for predictability, with 68.3% sensitivity, 86% specificity, and overall accuracy of 77.5%.

The Failure of Metal Cutting Tools at Tool/Work Disengagement
1993The paper presents recent findings obtained from our finite element modelling of a metal cutting tool engaged in an intermittent cutting operation. Finite element models have been developed for different configurations of the tool, the chip generated, and the workpiece.

Failure Analysis of Coatings on Concrete: a Failure Avoidance Tool
SSPC 2000, 2000Abstract Failure analysis is examined as a tool for designing coating systems for concrete and writing specifications to meet performance expectations. The intended function of the coating system is compared to common imperfections, which may or may not be acceptable depending upon the intended use.
