The interplay of dynamic laser and video projection and tool tracking from Extend 3D makes it possible to seamlessly link analog and digital processes. In doing so, the projection solution displays the positions for assembly or rework on the component, thus providing visual assistance to the worker. Once the position has been machined with the tool, the system registers this and hides the colored notes or switches to the next machining step. The completeness of the conversion and, if necessary, other process parameters are seamlessly documented digitally. Companies can gain valuable insights for process optimization from the recorded data.
