摘要：
Cutting temperature in workpiece has significant effects on machined surface integrity, including residual stress formation, metallurgical alteration, and microstructural change of workpiece material. In order to investigate temperature distribution in workpiece machined surface layer in external turning, an experimental investigation is carried out using physical vapor deposition (PVD) film method. This method provides an access to study temperature distribution as a function of depth in workpiece in turning. Effects of cutting parameters (cutting speed, feed rate, and depth of cut) on temperature distribution have been studied in dry cutting. Wet cutting condition was also studied in this paper to investigate the effects of different proportions of emulsion in cutting fluid on temperature distribution. This experimental investigation provides a new insight into the temperature distribution in workpiece machined surface layer in turning and is essential to the further research of machined surface integrity.
