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 …
Surface and Edge Quality Variation in Micro-machining of OFHC copper
The surface and edge quality of single crystal and polycrystalline copper workpiece has been observed to vary significantly as a function of crystallographic orientation. At the precision scale, the chip formation process is influenced by …
Variation in Machinability of Single Crystal Materials in Micromechanical Machining
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 …
Tribological Behavior and Cutting Performance of Lubricants in MQL Machining
The investigation using high vacuum cutting apparatus indicated the ester and oxygen were likely to enhance mutually their adsorption activities. The experimental facts obtained by normal atmosphere cutting apparatus demonstrated that a synthetic ester for …
Influence of Process Parameters on Accuracy of Microfeatures by Micromachining
Micromachining is a preferable fabrication method for tooling such as a micromold, rather than as a direct method of mass production. For tool fabrication, the precision of machining should receive much more attention than aspects …
Scalability of Tool Path Planning to Micromachining
Micromachining applications have received increased emphasis in recent years with the advent of new precision manufacturing applications which have stringent requirements for surface and edge finish. One of the main concerns in mi- cromachining is …
Micromachining and Burr Formation for Precision Mechanical Components
An understanding of burr formation and edge defects is critical to efficient production of machined features in precision components. Analytical models of burr formation and edge effects including the tool/workpiece interaction and material influences are …
