Connecting the KELCH presetting device with TDM guarantees correct preparation and measurement in the specified tolerance range of the tools. Functions: - Nominal data of tool assemblies, tool lists, holder/adapter are transferred to the tool presetting device from the TDM database - Measurements of actual data are transferred either per tool or per complete tool group from the tool presetting device back to TDM in the form of tool lists Benefits: - Direct connection to the database - No duplicate data - Continuous process flow from planning via NC-programming to machining, which increases productivity - Reduction of production times and costs - Machine downtimes, scrap and damages are reduced because of the electronic generation of special tool offsets
