A New Approach To Chip Breaking Application In Turning Operation Using Variable Feed Rates
Abstract
In machining operations, especially turning operations, there are many
factors that determine process efficiency and product quality. Factors such as
cutting forces, cutting zone temperatures, tool wear, chip morphology are the
basic elements that monitored in the development of machining applications. One
of the problems encountered during machining of materials commonly used by the
aerospace industry, such as Super Alloy, Titanium, Aluminum, is long and
continuous chip formation. A new methodology has been proposed in this study.
In this methodology, low frequency vibrations are used for chip breaking. In
this study, it is explained that it is possible to break the chip by using the
Computer Numerical Control (CNC) program within certain limits without using an
external device or chip breaker form insert.
