SPI SheetMetalWorks Technical

SPI SheetMetalWorks is 100% integrated with SolidWorks. The complete functionality of SolidWorks is available, ensuring the sheet metal part can be edited at any time. SPI SheetMetalWorks specifically addresses the needs of companies involved in the design and manufacturing of parametric sheet metal parts and assemblies. It leads to significant increase in ready-to-manufacture products and makes the design process instant, resulting in dramatic time savings between concept and the testing of actual parts.
  

What makes it the best-in-class solution?


SPI has developed software for the sheet metal industry for many years. We started with several other CAD systems and came to SolidWorks in the late nineties. There is a whole bucket full of experience. Don't hesitate: This is your chance to participate...
 

Sharp cornered design

A special feature of SPI SheetMetalWorks is the „sharp cornered“ design. In that case bending zones
are not filleted, notching is not necessary. By this the CAD model‘s size and the construction effort
decreases enormously. SPI SheetMetalWorks takes over the calculation of the fillets and automatically
creates the required reliefs. The Split Corner command allows for precise unfolding of closed boxes.
You do not need to design slots but just add split attributes to the corner areas. In many cases this
method is profitable. It even works with complex slant designs. Due to the fact that bending radii are
contained as attributes, you can modify them without re-designing the solid. The file is very stable
and is represented in a more clearly arranged way, the dimensioning is more comfortable. The figures
on the right hand side show such effects.
 

More than a simple flat pattern development

You can visualize the borders of the bending zones beneath the bending lines. Free form surfaces
as well as conical or cylindrical surfaces with large radii can be treated with a sequence of readyto-
manufacture bending lines for successive bending. The amount of facets for a freeform surface
depends on the settings of the parameters or of the possibly attached facet attribute. At the middle
of each facet line (bend line) the inclusive angle is displayed. To simplify the identification of bending
lines on the blank you can let calculate bending marks. Thus the worker at the bending machine has
a better orientation and will position the sheet metal even more effectively. The optionally created
bending line table delivers all the information needed for the bending process (e.g. angles and
radii). Line type, colours and layers of the contours can be customized to NC program standards. The
unfolding is available within the existing drawing, another part document or directly into a DXF-, XML or
GEO-file. The processed NC data are according to TRUMPF TruTops, WiCAM PN 4000 and others.
