I think it has been discussed before, but the search is notyielding much for results.

I am attempting to create a helical cut that would represent thecut a milling cutter would make on a tube as it is rotated andtranslated. The milling cutter remains perpendicular to the tube'scenterline at all times, and in this case the tube is rotated onit's axis 90 degrees and translated 16 mm.

The idea is this tube will have a solid cylinder sit within it.This solid cylinder will have a 2 mm pin pressed into the radialface, so it sticks out the side of the cylinder. This pin thenrides within the helical cut of the tube. This mechanism then hasthe ability to transform linear motion of one part into rotation,when the pin rides along the helical path and rotates the solidcylinder relative to the tube.

So I need to create a helical cut. I could do this in Pro/Engineer,and am having great difficulty doing so within SolidWorks. I am inthe process of doing some FEA work on this mechanism, so it'simportant that the surfaces be true and that the pin actually canslide within the helical cut-out.

Thanks so much for any help.SolidworksParts And Features
