Area of Science:

Materials Science
Manufacturing Engineering

Background:

Traditional manufacturing methods limit the production of application-specific cutting tools due to cost and volume constraints.
Tungsten carbide-cobalt (WC-Co) is a standard material for cutting tools, but its traditional processing has limitations for complex designs.

Purpose of the Study:

To develop and evaluate a manufacturing framework for producing application-specific cutting tools using additive manufacturing (AM).
To investigate the properties and performance of novel diamond-reinforced WC-Co composites created via AM.

Main Methods:

Design and fabrication of diamond-reinforced WC-Co cutting tools using laser-based directed energy deposition (DED) AM.
Microstructure and phase analysis of the manufactured composites.
Machining performance testing and comparison with traditionally processed commercial carbide tools.

Main Results:

Successfully manufactured diamond-reinforced WC-Co composites using DED-AM without large-scale cracking.
Observed improved microstructure with multiple reinforcing phases due to diamond incorporation.
Demonstrated enhanced machining performance of the AM-produced diamond-reinforced tools compared to base WC-Co and commercial carbide tools.

Conclusions:

Additive manufacturing, specifically DED, is a viable technology for creating multifunctional, application-specific cutting tools.
Diamond reinforcement significantly improves the processing, microstructure, and machining performance of WC-Co cutting tools.
This approach addresses manufacturing demands for advanced, customized tooling across various industries.
