Chamfering a slot in a piece of tube.

I have a piece of tube that will have 3 slots machined .250" from the
end and are 1.500" long. The slots will be .250" wide and have
radiuses at each end of .250". The slots must have a 30 degree chamfer
around the periphery of the slot. I tried the chamfer console and it
will only allow me to use 0x0 or 01x02. I cannot get the chamfer on
the slot for some reason. The chamfer must start at the bottom edge of
the slot and open up toward the sides of the tube at 30 degrees.

Any suggestions?

Thanks, Steve

 

How about a variable section sweep? Normal to projection: make an
embedded datum plane through the two long sides of your slot to use as
your direction reference.

 

Hmm... I never noticed this limitation. It must have something to do
with placing a chamfer on a round surface. The easiest workaround I
can think of is to just use the O1 X O2 option and calculate for
yourself what the two distances should be. For example, if you wanted
a 30deg chamfer with a .05" long side, then the other leg would be
equal to .05*tan(30) = 0.0288. That way you don't have to mess around
with VSS and trajectories. It's still one clean chamfer feature in
your model tree. If you want to be able to easily adjust the chamfer w/
o repeated trig calcs, you can easily create a relation that
calculates O2 based on O1.
