Ducts (square and rectangular) must be drawn in the corners as follows: outside radius = 2x wall thickness and inner radius = 1x wall thickness. The value “2” is the average value of the size of the radiuses specified in the standard.
In case of aluminium tubes (square and rectangular), the corners must be drawn as follows: outer radius = 0.5 and inner radius = 0.
247TailorSteel cuts 2.5D. This means that the cutting edge of the ducts is perpendicular to the material (centre-orientation). In case of tubes, it is directed towards the centreline. Some examples are discussed later in this manual. The software of the 247TailorSteel converts the 3D-cutting edges into 2.5D-cutting edges.
Wall thickness options:
Maximum weight of the product per metre: 32 kg.
Maximum length to be laser cut from one piece: 5,800 mm.
The tolerances on the cut contour, centring of the cut contour and on the total length amount to +/- 0.2 mm. The tolerance is strongly influenced by a number of factors, such as:
