When CO2 laser cutting, fiber optic laser cutting, flame
cutting, laser welding etc. are gaining momentum across the
sheet metal fabrication industry, it becomes vital for sheet
metal contractors and fabricators to stay aligned with these
new developments and stay profitable. Instead of conventional
metal cutting and joining process with machine tools, these
methods are gradually taking over the fabrication business and
hence fabricators need to align their designs and drafts with
the upgrades. Cleaner environment, efficient process, saving of
metal scrap and flexibility of these new technologies are some
of the key factors that run in favor of discarding conventional
processes, as new technologies continue to grow.
It goes without saying that when laser cutting or welding of
sheet metal is involved, it isn’t about fabrication drawings
[Fig. 1]; it is about nesting drawings and reports. Fabricators
insist [and should insist] on having a comprehensive nesting
report form their CAD design engineers in order to utilize
metal judiciously and effectively. Enclosures, HVAC ductworks
and other sheet metal components are seen as commodities and
companies from all over the sheet metal fabrication industry
are looking for reducing costs by quick fabrication and
bringing these commodities to markets faster.
Standalone traditional CAD systems aren’t enough for laser
With sheet metal fabrication, it isn’t about where you start
from; it is in fact all about what will be the end product.
While all application materials require precision in laser
cutting for efficient finish and accurate geometry, designs too
have got to be precise and comprehensive. Designs that are
focused on the fabrication process chosen, materials to be used
and machine technology to be deployed, are essentially the
designs of requirement.
