Burr research is undeniably highly complex. In order to advance understanding of the process involved several techniques are being implemented. First a detailed and thorough examination of the burr forming process is undertaken. The technique …
Development of a Drilling Burr Control Chart for Low Alloy Steel, AISI 4118
A control chart for drilling burr formation for low alloy steel, AISI 4118, was developed. A drilling burr control chart, based on experimental data, is a tool for the prediction and control of drilling burrs. …
Thrust Force Analysis of Drilling Burr Formation Using Finite Element Method
This study is focused on thrust force analysis of the drilling burr formation. A finite element model (FEM) for drilling burr formation was proposed with a stainless steel (AISI 304L) workpiece and a conventional twist …
Finite Element Modeling of Burr Formation in Metal Cutting
In order to advance understanding of the burr formation process, a series of finite element models are introduced. First, a finite element model of the burr formation of two-dimensional orthogonal cutting is introduced and validated …
Application of Four Levels of Drilling Burr Minimization Strategies
Burr problems can be approached at various stages from design to final processing. Four levels of burr minimization strategies are proposed. A case study is included to illustrate the application of these strategies. One of …
Modeling of Inter-layer Gap Formation in Drilling of a Multi-layered Material
With increases in the use of multi-layered material in the aerospace industry to reduce weight while still meeting strength requirements, studying inter-layer burr formation in drilling of a multi-layered material becomes more important. Inter-layer gap …
Finite Element Modeling of Burr Formation in Drilling of a Multi-Layered Material
For an optimization of a drilling process to minimize burr formation, control chart or empirical model from design of experiment can be used. However, direct measurement of inter-layer burr is limited experimentally in the case …
Surface and Edge Quality Variation in Precision Machining of Single Crystal and Polycrystalline Materials
The surface and edge quality of single-crystal and polycrystalline copper workpieces has been observed to vary significantly as a function of crystallographic orientation. On the precision scale, the chip formation process is influenced by the …
Investigation of Tribological Mechanism of Near Dry Machining (NDM)
This paper describes tribological mechanism of Near Dry Machining (NDM). Two special setups to understand Tribological mechanism of near dry machining are designed. One is mainly to measure the behavior of some fed gases in …
