- For many decades there has been an awareness of cutting tool edge condition and tool surface finish and the effect it has on piece part quality and tool life. There have been many independent studies, tests, and implementations of edge conditioning methods to create extended life in turning, drilling, and milling cutter tooling – some published but most kept “secret” as a manufacturing advantage. — Jack Clark, Surface Analytics LLC and Colorado State University
The “Deburr/Finish Tech Group” of the SME has tasked itself to manage the project and use it’s member resource pool to provide tooling, applications, and the necessary documentation and reporting to objectively test cutting tool edge radius improvement on tool life and piece part consistency. This is a proposed outline on how to organize and conduct such a test. It is the intention of the participants to publish a document, possibly an SME Technical paper or article, at the conclusion of the study.
