Creating Parts using Thickened Trimmed Surfaces

[Malcolm Crowe]

This is another example of creating sheet metal parts using thickened trimmed surfaces. Again it involves using a "Structured Part" to contain the 2D sketches and surfaces used to create the thickened parts. The difference here is that we are using the "Extrude" tool (outside cut) to trim the surfaces to the desired profile, before using the "Thickening" tool.

In this particular example (a ROPS Grille), the Vertical Blades need to have an even spacing (100mm) at the top and bottom, and angled towards a common point (operator), and welded to inclined Lower and Upper Plates. The geometry of the fabricated part dictates that only the outside edges of the Vertical Blades make contact with the Lower and Upper Plates. As a result, the surfaces constructed in the "Structured Part" are the outside faces of these Vertical Blades. From these construction surfaces the "Thickening" is directed inwards to create the finished parts.

The attached video and model demonstrate the technique.

Nice work!
