The Formation And Properties Of Machining Burrs, Laroux K. Gillespie
The Formation And Properties Of Machining Burrs, Laroux K. Gillespie
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The formation of burrs in Machining Operations occurs by three Basic Mechanisms:
1) Lateral Extrusion of material
2) Bending of the chip
3) Tearing of the chip form the workpiece
Each of these mechanisms has been studied analytically and compared to experimental results. The agreement between predictions and measurements has been found to be close.
Drilling, milling, grinding, and turning burrs were produced in 303Se stainless steel and their properties were related to tool geometry, feedrates, and depth of cut. One thousand measurements were made and subsequently analyzed by analysis of variance techniques. The properties measured include burr length and …
