Ball End Mill Sweep

634 Views, 45 Replies
11-20-2008 12:20 PM
Is there a way to do a clean sweep that imitates the shape a ball end mill? I'm trying to create a path that has 90 degree bends and whose end product looks like it was cut by a ball end mill. If there's a way to avoid sweeping the straight areas and then revolving the corners, I'd be happy to know.

Thanks!

and technically thats not the correct shape a ball end mill will leave. If you need that actual path/shape that a ball end mill will create you need additional steps besides a simple sweep.

Could you save in IGES or STP format?

Did you use the REVOLVE function at the corners?

Thanks.

Yes you need to do a straight sweep first, then revolve (cut) at the end of the sweep to get the rounded end, then another sweep perpendicular into the center of the revolve.

So 2 straight sweeps and 1 revolve to make a right angle.



attached is the step file

Here is the result I got in another SoftWare that will allow swept cut of one solid body through another.

That's what I'm looking for. What software did you use to make that?

Created this in Inventor 2008 using an extruded cut feature and a couple of fillets.
