How can I make a an O ring adjustable . (made with a circle and revolve feature) Whats the best way to achives this as i have multiple assemblies of parts with square O-ring grooves.I want to make the Circular O-ring adjustable with the variables tool so that it can fit the squared groove.
Solved! Go to Solution.
Since the O-Ring itself get deformed when in place I would suggest you to use an ellipse as revolving section and place the dimensions of the 2 main axis.
Make the O-Ring adjustable and use the 2 dimensions to control the "shape" of the oring in the socket.
If you use 2 planes to control the section elipse instead of the axis dimensions you could use the adjustamble part to match the socket.
I know you didn't put it out there for reveiw, but an o-ring groove like that is a real B***H to machine accurately with a nice finish. If at all possible I would recomend trying to design that part with either a face groove type seal, or a stepped groove for the o-ring.
