Targeted and fast tool repair

The challenge

A tool has worn so much during production that the parts produced with it no longer possess the required geometry. Result: The tool needs to be repaired. For this, material is often welded onto the tool and reworked iteratively until the tool again has the correct shape, usually making this a fairly time-consuming procedure.

The solution

With the aid of an ATOS system, users can scan the tool in 3D and compare the measurement data with the data of the CAD model of the tool. In this way, it is very easy to identify the worn sections of the tool. This information can then be used to carry out repair work in a targeted manner, with new material only having to be welded onto the critical area.

The tool, including the welded-on layer, is then scanned again and the measurement data is compared with the CAD data. This will immediately indicate the machining allowance, which is then transmitted to the milling machine where the surplus of the welded-on layer can be milled off in a very short time, and a productive tool again be made available.
