Chamfering Question 1

[bluesman0007]

Hello All,

I will try to describe my problem and if it's a simple fix excuse me for asking. I have a yoke shaped part and I only want to chamfer the radius and not the flat leading up to the radius. I have turned off "tangent propagation" and cannot just chamfer the radius it automatically continues on to the flat. Have tried everything to deselect etc. Is it possible?

Thanks in advance.

Without seeing the part this might be a duff idea, but my first thoughts were try editing the features and untick "merge result" therefore creating a number of separate bodies.

Do your chamfer then "combine" the bodies.

You need two flat surfaces for a chamfer. Try a revolved-cut?

Sounds like a loft cut to me.

Just out of curiosity, why would you loft a cut that seems like it would be of uniform cross-section and about a constant radius? I have to agree with Chris...revolved cut.

 

[hendersdc]

I like the loft cut because if the cord length of the radius changes the loft will rebuild automatically. You wouldn't need to go back and modify the angle like in a revolve cut. This only applies to an outside radius not an inside. Personal prefference really.

It would help to see a pic.

Thanks everyone, I'm at home so will try when I get into work in the morning. I think I'm most comfortable with the revolved cut but just for kicks will try the loft. I've never been able to get the image thing to work for me, sometime I'll try again.

Thanks again, I love this forum.

Create a very narrow cut (0.0001") cut at right angles to and just covering the chamfer so that it doesn't cut the parent body. This will stop it propagating;(see below) I often use this if I need to stop a chamfer or fillet short of its usual end to simulate the run-out of a tool. In this case I make a sketch for a revolved cut on this "stopped end" face.

SincoTC,

That's pretty smart! Cut the edge that is propogating to stop the chamfer...I like it!
