Composition: Specially engineered, cobalt-enriched carbide grade with thick K-MTCVD-TiCN coating layer, an Al2O3 layer of controlled grain size, and outer layers of TiCN and TiN for maximum abrasion and wear resistance for high-speed machining. That equipment was focused not only on capacity but also on efficiency. What are interpolation and the 3 common methods of interpolation? For turning, if the influence of turning tool installation and cutting motion is not considered, the cutting plane can be considered as a vertical plane; the base plane is a horizontal plane; when the main cutting edge is horizontal, the section perpendicular to the main cutting edge is the main section. According to Haberski, this enables a quick response to part changes and easily accommodates smaller batches as well. These dies reflect the high surface finish capabilities from the grinding process. (3) The main deflection angle Kr is measured in the base plane, which is the angle between the projection of the main cutting edge on the base plane and the feed direction.
