Tool-Life Distributions—Part 2: Multiple-Injury Tool-Life Model

Journal of Engineering for Industry, 1977
The single-injury tool-life model developed in Part 1 of this paper is extended to the case of tool failure due to a multitude of injuries. The expected tool-life distribution in the case of tool failure from multiple injuries due to constant, time-independent stochastic hazards is shown to be a gamma distribution.

Evaluation of Tableting Tool Life Records

Journal of Pharmaceutical Sciences, 1968
A study of tableting tool life records, accumulated over a period of 8 years, has served to develop and define relationships between tool performance and the many operating variables that exist in routine tablet production. The effects of these numerous factors on punch and die life have led to conclusions involving techniques for extending tool ...

Wear and Tool Life of CBN Cutting Tools

The International Journal of Advanced Manufacturing Technology, 2002
= T(vc) tool life curves are of "dromedary" type. The tool life maximum point moves up and down according to changes of depth of cut and feed-rate values. The reasons for polyextreme tool life curves and moving maximum tool-life points are discussed in the paper. A new general tool life Eq.

Cutting Tool Life Comparisons

1985
Single point tool performance data are presented, concerning the use of tungsten carbide, alumina, sialon and cubic boron nitride cutting tools, when machining a variety of hardened and annealed ferrous workpiece materials. When cutting hardened die steel Rc 55-61, at speeds between 50–100m /min with a constant feed rate of 0.12mm/rev, two of the three

Tool Life Variation and Its Influence on the Development of Tool Life Models

Journal of Engineering for Industry, 1977
An investigation into the nature of the inherent variation of tool life over a range of cutting conditions for a finish turning process is presented. In this study, tool life is based upon a fixed amount of wear on the clearance face of the tool. The nature of tool life variation as a function of the prespecified wear level is also examined.

Radioactive Cutting Tools for Rapid Tool-Life Testing

Journal of Fluids Engineering, 1953
Abstract This paper presents an abbreviated method of measuring cutting-tool life using radioactive isotopes as tracers to measure the “instantaneous” rate of tool wear. This method consists of machining with a tool which has been rendered radioactive by neutron irradiation in a nuclear reactor, collecting the resulting chips, and ...

Tool Life Analysis and Forecasting: 2. Forecasting Tool Life Using Neural Networks

1993
Abstract : To achieve Semi-untended or untended machine operation in a factory environment forecasting tool life is a prerequisite. In order to achieve this rock island arsenal initiated a tool life test program for 3/4 inch drills. AMCCOM systems analysis office has statistically analyzed this data and employed in the development of a neural network ...
