On Chip Morphology, Tool Wear and Cutting Mechanics in Finish Hard Turning

Critical cutting speed for onset of serrated chip flow in high speed machining

“…The growing demand for enhancing production efficiency has stretched a rapid development of high speed machining (HSM) technology, which has many advantages such as high removal rates, low cutting forces, leading to excellent dimensional accuracy and surface finishing quality [3,4]. However, higher cutting speed usually renders the emergence of serrated chip flow [5], which ties up with decreased tool life, degradation of the surface finish and less accuracy in the machined part [6]. So, to predict the critical condition and especially the critical cutting speed for the onset of serrated chip flow could be of significant importance.…”

A study of the impact of blade wear on specific energy in precise turning of 16MnCrS5 steel (AISI 5115)

“…Zasadniczo, naukowe i inżynierskie problemy obróbki na twardo dotyczą takich zagadnień jak mechanika procesu, zużycie ostrza, stan warstwy wierzchniej i dokładność wymiarowa [3,4,5]. Bilans energetyczny tego procesu nie jest zbadany dostatecznie, chociaż oddziaływanie ostrza na twardy materiał jest bardzo specyficzne.…”

The study of the process of chip segmentation in case of edge cutting machining of titanium alloy

“…In the course of the past several years the analysis using finite-element method (FEM) has become the main tool for modeling the cutting process [3][4][5][6][7][8][9]. T. Thepsonthi, T. Ozel used the FEM analysis in order to study the impact of a cutting tool with CBN coating for processing of Ti6Al-4V titanium alloy.…”
