Cutting tool geometries play important roles in tool performance, such as tool life, surface
integrity, and cutting force. The most common commercial tools edge geometries are honed,
chamfered and hone-chamfered. This study investigates new ways to develop tool geometry.
An uncoated carbide tool is used in the orthogonal cutting of AISI 4140. By observing the tool
geometry changes in the machining process with white light interferometry, a new tool wear
geometry model has been proposed. A non-destructive tool wear measurement is discussed
as well. In addition, this study presents the machining result comparison between the new
and conventional geometries as well as the failure analysis from both experimental and FEA
perspectives. / Thesis / Master of Applied Science (MASc)
