In high speed cutting, the mean flank temperature is not likely to be less than that on the rake face, that is, the cutting temperature, as the undeformed chip thickness is very thin and of the same order of cutting edge radius. To measure the flank mean temperature, it is critically important to mount the artificial thermocouple properly in the workpiece. A new thermocouple mounting arrangemen...

The paper presents results of an analysis of acoustic emission (AE) signals obtained during laser cutting of a steel plate, which is frequently used in the production of automotive body components. The acoustic emission in the plate, which is produced by various physical phenomena occurring during the laser cutting process, was measured with contact PZT sensors. During the laser cutting process...

Lasers are widely used in industry as cutting tools due to ultra flexibility of the cutting conditions, obtaining high quality end product, quick set up, non-mechanical contact between the workpiece and the tool, and small size of the heat affected zone. In the present study, laser gas assisted cutting process is examined. Statistical method based on factorial analysis is introduced to identify...
