Influence of Exit Surface Angle on Drilling Burr Formation
The influence of an exit surface angle on drilling burr formation was analyzed. The experimental research found that a burr forms on only a certain portion of a hole when an exit surface is not …
A Study on Tribology in Minimal Quantity Lubrication Cutting
Despite the fact that minimal quantity lubrication (MQL) machining produces almost similar cutting performance to conventional flood supply machining while using much less metal working fluid (MWF), it has not been fully utilized in industry …
Investigation of Adsorption Behaviour of Lubricants in Near-Dry Machining
Near-dry machining (NDM) is a technology with many ecological and economic benefits that uses very small amounts of metal working fluid (MWF). In order to increase the applications of this technology, the tribological mechanism during …
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 …
Variation in Machinability of Single Crystal Materials in Micromachining
For practical application of micromechanical machining, four levels of process realization are required; fundamental understanding of process physics, development of microplanning (processing parameter optimization), macroplanning (tool path planning), and design optimization. This study surveyed the …
