Prediction of tool wear based on GA-BP neural network

Proceedings of the Institution of mechanical engineers. Part B, journal of engineering manufacture, 2022
The anisotropy and nonuniformity of wood-plastic composites (WPCs) affect the milling tool, which rapidly wears during high-speed milling of WPCs. Thus, the evolution mechanism of tool failure becomes complicated, and the prediction of tool wear cannot ...

Wear mechanism of ceramic tools

Wear, 1993
Abstract Cutting tests were performed using ceramic cutting tools under continuous cutting conditions. The tests were carried out on AISI 1040 steel, with cutting speeds ranging from 5 to 11 m s −1 . The wear mechanism was investigated for both crater and flank.

Thermoelectric wear in tools

Wear, 1973
Abstract Thermoelectric tool wear was measured by the thermocurrent generated in Machine-Tool-Workpiece-Machine (MTWM) circuit. The relationship between thermocurrent and the cutting parameters in the machining of EN 24 steel with a carbide tool and the significance of the influencing parameters are assessed statistically.

Tool Wear or Tool Design

1975
There are a group of problems which on face value appear to be associated with tool-wear mechanisms, but which, after a careful examination are either design based or metallurgical in their nature.
