The automated cutting of sheet metal has traditionally been done according to engineering drawings which are printed out on hardcopy. Therefore, every time a test piece was cut, it would be compared to one of these drawings and if the piece fails, many hours would be spent changing the drawing until a workable finished product was produced.
Now the fabrication sector is armed with a new tool known as re-engineering, which does away with engineering drawings. Suppliers of this technology, Maxitec deal in sheet metal machinery, where an entire job design is performed in a digital environment before a single part is produced.
And it takes one part to test for accuracy. Almost every time, the result is near-perfect and if there is any slight anomaly it can be quickly adjusted so production is not affected whatsoever. Re-engineering is highly suitable in most sheet metal machinery such as a punch/press or laser. An operator can take the first part off and within 15 to 20 seconds the software running the equipment returns a report.
This facilitates instant and accurate changes so the operator can keep working rather than sending away checks against engineering drawings, effectively providing reverse engineering. There is no need to redraw the engineering drawings which could take about eight hours work. Now the user receives an instant ‘snapshot’ of the job and work begins.
