Abstract

This paper presents an experimental method of determining the velocity of chip flow on the rake surface of a cutting insert during the longitudinal turning of Ti-6Al-4V titanium alloy. A Seco CNMG120408-M1 833 carbide cutting insert without a protective coating was used for the purposes of research. In order to record phenomena in the cutting zone, a PHANTOM V5.2 high-speed camera was used and placed above the area of machining. The camera recorded the process at a speed of 3000 fps. Placing the camera near the cutting zone allowed recording the process of chip formation and its flow along the rake face of the insert. Trials of longitudinal turning were performed in accordance with the test plan, where vc and f were the independent variables. In addition, the tests were performed for two different cutting depths. Processing and analysis of the obtained video sequences were performed with the use of CineViewer 663 and Tracker computer applications. Experimental determination of the velocity of chip flow at the rake face of a cutting insert was conducted by analysing the movement of the characteristic point on the outside side of the chip. Analysis of variance for the obtained results was performed using ANOVA and the regression functions were determined.
