The creation of an NC program is very time consuming without access to a tool database. The interface TDM-ESPRIT supports your CAM process optimally with access to a central tool database. With the interface, the technology know-how is available in all phases of the CAM planning process. Geometry and technology data of tool assemblies are transfered via the interface. The access to the online database takes place via the integrated tool selection in ESPRIT. Data gets standardized through a central database and can be used from each ESPRIT workplace. The retransfer of tool lists to TDM is possible.
