chamfer command giving two different results

[gargoyle27]

i have a set of pins that had a cross hole through them, when i go to add a chamfer on both ends of the hole they end up different, the chamfer is set to .125" for both, but it comes out with a different result, how do i make it make them the same?

 

here is one of the pins

This has been a known problem for years.

I tried deleting in 2011 and it reproduced.

I will try recreating the part from scratch in 2011 (I thought this one had been fixed for 2011).

Incidently, even if it worked - chamfer would not give you the same geometry as a standard revolving cutting tool - the result would be more similar to a hand deburring operation. I would use Revolve rather than Chamfer.

yeah true, i think i will use revolve instead, thought there was something wrong with my computer or the way i used chamfer or something

No - this one is definately a bug in my opinion. I'll have to give it a try in SolidWorks and Pro/E and see what happens.

 

Also, instead of Revolve you can also put in countersink angle using Hole feature rather than extruding a circle and then revolve.
