ogrzewanie laserowe - Opis:
- The article presents the results of the influence of laser heating on the properties of replaceable cutting inserts with various anti-wear coatings. Based on the existing own and external publications, it was found that in order to improve the cutting properties (durability in the cutting process of steel), it is extremely important to increase the adhesion strength of hard coatings to the cutting inserts. For this purpose, laser heating with different values of the laser beam power density was used. First, the measurements of the adhesion, and then the wear and durability of the cutting blades in the process of longitudinal turning of the commonly used nitriding steel were carried out. In order to confirm the adhesion measurements carried out on the basis of the vibration signal evaluation, observations were additionally made using a scanning microscope and using 2D and 3D images on a profilometer. As a result of the research, it was found, among other things, a significant correlation between the values of adhesion of coatings to cemented carbide substrates and the durability of the blades in the steel turning process. A significant effect of laser heating on the above-mentioned properties of replaceable cutting inserts was observed. The most favorable value of the applied power density was determined, for which the blades have the best cutting properties. The research indicate that significant increase in adhesion and tool life can be achieved for the laser beam power density of up to 8280 W/cm2. In the most favorable case, an increase in tool life of about 48% was obtained for the indexable cutting insert with a TiCN coating when turning 41CrAlMo7-10 steel.
