Prediction of wear of carbide cutting tools

International Journal of Production Research, 1977
SUMMARY This paper presents an analysis of tool-wear data mainly from the view-point of flank wear. Mechanism of wear of cemented carbide tools is considered to be of two main types: (i) mechanical interaction, with adhesion-transfer type being the main cause and mechanical abrasion of secondary importance; (ii) thermochemical type, which is considered

Feature selection for predicting tool wear of machine tools

The International Journal of Advanced Manufacturing Technology, 2020
In this study, the vibration transmitted solely from a spindle to the worktable is proposed to be a crucial feature of wear prediction models for machine tools. To validate the effectiveness of the proposed feature, a feature ranking and screening methodology was also used for developing a tool wear prediction model.

Analytical prediction of cutting tool wear

Wear, 1984
Abstract An analytical method is presented which enables the crater and flank wear of tungsten carbide tools to be predicted for a wide variety of tool shapes and cutting conditions in practical turning operations based only on orthogonal cutting data from machining and two wear characteristic constants.

Prediction of tool wear in micro USM

CIRP Annals, 2012
Abstract Micro Ultrasonic Machining (USM) is used to generate micro features in hard and brittle materials. However, tool wear occurs during machining. In this paper, low cycle fatigue is identified as the dominant factor causing tool wear in micro USM. A theoretical model is proposed to estimate the tool wear.

In-Process Prediction of Milling Tool Wear

1984
In process sensinq of cutting tool condition, which may include wear as well as breakage, has become a major interest to machine tool users. The various methods proposed so far can be divided into direct and indirect methods. A good example of the former is the use of a TV camera directed at the cutting zone, so that careful examination of the tool ...

Research of Tool Wear Monitoring and Tool Life Prediction Models

2020 13th International Conference on Intelligent Computation Technology and Automation (ICICTA), 2020
Tool wear is inevitable in manufacturing and affects the surface quality and geometric tolerance significantly. Detection of the tool wear and residual life can significantly improve the usage rate of machining and reduce the economic losses due to the tool breakage so as to optimize input-output ratio.

Tool Wear Prediction in Broaching Based on Tool Geometry

Volume 9: Manufacturing Materials and Metallurgy; Microturbines, Turbochargers, and Small Turbomachines; Oil & Gas Applications; Steam Turbine
Abstract The aircraft engine is a safety-critical part of an aircraft. Constructive modifications resulting in ecological and economic improvements of the engine lead to necessary changes in manufacturing processes. The turbine discs in the low-pressure section are made of temperature resistant nickel-based superalloys.
