Flip countersunk hole IV9

[Josh_Petitt]

Is there a way to "flip" a countersunk hole so the hole starts at a plane, extrudes a specified distance then goes to the countersink diameter for the rest of the part depth? I've attached a picture to help demonstrate what I'm saying.

I've ran into this situation a fair bit, and first I tried using a regular countersink hole with the countersink diameter smaller than the hole diameter (i.e. hole becomes countersink and vise versus), but got an error message 😞

Josh,

Before helping you resolve this issue, I would like to understand your
request a bit more. You want CounterSink hole, not CounterBore, right?

oops, thanks Johnson, I meant to say CounterBore (like is shown in the picture).

Josh,

Not sure if I understood your question correctly. For what I see from the
picture, you can make a workplane above the surface where you want the
countersink/counterbore depth, then sketch a point on this workplane and
make countersink/counterbore hole from there. Attached is a screenshot for
what I described. Hope this helps!

Josh,

There are possibly many ways to create the flip counterbore. But none of
them can be done through one step. Here are a few ways I think of.

Solution#1: a hole and a workplane
1) Create an offset workplane from the face where the holes will be normal
to.
2) Create a sketch on the workplane.
3) Create sketch points for placing the holes.
4) Insert CounterBore holes.

Solution#2: a hole and an extrusion cut
1) Create an offset workplane from the face where the holes will be normal
to. This will be where the counterbore start.
2) Create regular drilled holes on the face.
3) Create a circular extrusion cut based on the offset workplane.
4) Extract the two features as iFeature.
5) Insert the iFeature as you wish.

Chun,

Keep including more screen shots of Inventor 11, so we can see all the new
features. 🙂

I posted a "punch tool" method of doing this a while back. Hopefully we will see this functionality built into the hole tool in the future. In my former life as a machinist I was usually working from cast surfaces where the c'bore depth was reference only and the important dimension was the length of the clearance hole from the clamping surfaces as that determined how far the fastener went into the threaded mate.

If you do this sort of thing frequently, perhaps make an iFeature?

Create a Punch tool with the iFeature and it is as simple as placing sketch points to "punch" the holes just like the Hole tool works.

Thanks for the ideas, currently I'm using method #2 you described. I may go ahead and make this an iFeature to save some clicking.

yes, exactly!
