| Popis: | The paper presents the universal mathematical model-based geometric analysis of a composite hob with replaceable sintered carbide cutting inserts. Composite hobs are characterised by lower accuracy compared to monolithic hobs and are generally used in roughing. Based on a computational algorithm developed by the authors of this study a computer program has been created to model the position and the geometry of the cutting insert placed on the rake face. A generalised case of a composite hob with a flat rake face not parallel to the hob axis and with rake angles different from zero has been analysed. Methods for correcting the cutting insert position and geometry to improve the composite hob accuracy are presented. |
