Offset & angular displacement compensation

At Euralco we like to embrace the challenges our clients are struggling with. A couple of months ago, we machined various cut-outs and hundreds of holes into 150 aluminium sheets. Fully in accordance with our clients’ set of drawings. After delivery of the first 20 assembled products to their end-client, a modification was requested. Approximately 200 existing countersink holes needed to be enlarged in exactly the same location. Another 50 countersink holes to be added. How to convince a client, who is understandably hesitant that all previous works and materials are to be scrapped? Before we encourage you to read further about our approach, let us serve you by showcasing this process in less than a 1 minute.

Babysteps to convincing results:

  • As our robot loads sheets on the machine with an accuracy of 1 mm, the machine’s reference pins improve the accuracy to 0,3 mm.
  • By using the measurement probe, we can further improve the sheet positioning accuracy to 0,05 mm.
  • By drilling an existing countersink hole with the same tool, it was impossible to see the difference (e.g. ovality) with the naked eye.
  • That’s why we engraved two 100 x 100 mm crosses 0,1 mm deep over a diagonal distance of 3.000 mm. After changing the sheets’ position several times, we ran the test again and again and again. When we found identical crosses, we knew that offset and angular displacement compensation was absolutely perfect.

Herewith we convinced the client and got the order. Another happy Euralco client!
