Through this interface the tool database TDM and the technology database RCS are constantly synchronized. Technologiedatenbank von RCS ständig synchronisiert. This supports an optimal continuous cAM-process. Functions: - Fast selection of tools in TDM directly in the RCS-technology database - Transfer of information and defined tools from a tool list from TDM as tool library to RCS - In form of tool lists all used data of the nc-program is re-transfered from RCS to TDM - By fast selection of tools and efficient data maintenance, savings in production time are possible. The extension: CAD features: Through an easily in TDM created tool contour, RCS can create a simulated tool assembly with real rotation symmestrics.
