Fuzzy stability analysis of regenerative chatter in milling [PDF]

, 2010
During machining, unstable self-excited vibrations known as regenerative chatter can occur, causing excessive tool wear or failure, and a poor surface finish on the machined workpiece. Consequently it is desirable to predict, and hence avoid the onset of

Influence of Surface Finish on the Tribological Performance of AlTiBN Coatings Deposited on Forming Tools

Advanced Engineering Materials, EarlyView.
Aluminum and nitride coatings are used in industry because they are hard, resist wear, and protect against oxidation. Adding boron can improve friction behavior and other properties. This study tests coatings on surfaces with different finishes. Results show smoother surfaces perform better, while rough ones wear faster, although coatings can reduce ...

Development of the intelligent cylindrical grinding system considering the thermal deformation of a workpiece

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2018
In cylindrical grinding, the size accuracy of a workpiece decreases due to the thermal deformation of the ground workpiece. To improve the size accuracy, it is necessary to consider the thermal deformation of the workpiece during grinding process.
