Efficient NC programming also requires good tool management for the administration of complete tools, cutting parameters, tool geometries and other technologies. NX provides the option of tool management via ASCII databases. Janus Engineering AG has developed the TechnologyManager for this purpose, as it gives this simple type of data structure a comprehensive, database-like and graphically-focussed functional interface. A key benefit is that the implementation and maintenance of the data is much more cost-effective. Both the close linkage to the NC programmer's requirements, as well as the availability outside the CAM system, in the workshop, the tool preparation centre, the warehouse, the AV and in the commercial area, etc., turn the TechnologyManager into a universal tool for comprehensive technology management.
