Autodesk Inventor Sheet Metal Tutorial || Contour Roll Tool

In this tutorial we are going to discuss about the Contour Roll Tool in detail. This tool is used when we want to create a sheet by revolving a profile consisting of lines arcs, splines or elliptical arcs around an axis.

1. Here we have a sketch profile which is drawn previously.
2. Activate Contour Roll tool from the Create Panel of Sheet Metal Tab.
3. In the Contour Roll Tool Dialogue Box we can see Profile Selection is active.
4. There are four different options available in Unroll Method.
5. Let us first see the Centroid Cylinder option.
6. First select the profile then Axis of revolution.
7. Here we can see it is telling what would be Neutral Radius and Unfold / Unrolled Length of sheet.
8. Click Apply button to create the feature.
9. Activate Create Flat Pattern Tool and check out the extents of the sheets.
10. The Length mentioned here is the same as it was in the Contour Roll dialogue Box.
11. Let’s see the another option Custom Cylinder.
12. Here we have to define Neutral Axis in addition to profile and Axis of revolution.
13. Here it states that the Unrolled length would be 78.54 mm.
14. Again check the Unfolded sheet to find the difference.
15. The next option is the developed length or Unrolled Length…
16. Here we will fill the same 78.54 length that we got in the Custom Cylinder unroll method.
17. After defining the Profile and Axis we get the same 50 mm radius of Neutral Axis that is mentioned in our sketch.
18. In the last method we will only define Neutral Radius along with Profile and Axis.
19. Here we can see the Unroll Length will be 78.54 if we defining the Neutral Radius to 50mm.
