I will try and reply to the correct thread this time, darn it. If the 2D cutter profile is perpendicular to the helical cutter path will this give you the geometry you are looking for? See attached.
Nope. For transporting bottles, the bottle needs to stand upright, perpendicular to the screw axis. Your screw forces the bottle to lean over at the helix angle. The screw can be fabricated by translating a vertical end mill along the axis of the screw as the screw is turned at a constant rate (for a fixed-pitch screw). The trick is to figure out how to generate the 2D profile that results, since we don't have the ability to sweep a 3D object (cylinder, in this case) along a path (coil, in this case).
If the model is used in a drawing, it will look like the real thing. If you know what you're doing, it will take 5 minutes to produce a drawing that'll tell the machine shop how to make the part, and obviously it will work. I've made this point before, but it seems you want to have the last say and like to nitpick, while missing my point about digital prototyping.
I won't bother to respond to you again, you can have the last say. I've made my point, twice in fact, hopefully it will sink in this time.
Dear whunter, I had absolutely no intention of hurting anybody's feelings here. This is the issue of academic disscussion about Inventor's ability to perform very specific task, not the issue of manufacturing particular part. In this case - of course - the problem will be solved long time ago after 5 minute conversation with average skilled machinist.
Another solution, this one develops the 2D shape to sweep along the helix. (IV 2012 format). As others have said it would be nice if solid sweeps were included. Solidworks tool is pretty limited and fairly confusing on its own, but at least they are trying.
The interference between the tool and shaft is about .00017 in^3, very evenly distributed, likely due to the surface approximation. If you have IV Pro, the simulation shown in the included video (mp4 format) is included.
Bravo! It seems you've made exactly what dnewman ordered !
It is unclear for me, however, how did you get this 3D Sketch3 curvature. There's a work point set on Sketch 3 projection (how?), which is used for establishing Work Plane3, than you get this 3D Sketch3, later mirrored ... would you kindly guide me to this point?
