Help need with odd Chamfer /Pocket feature

Hi,

 

I having problem creating this feature I have attached some pictures to help illustrate what I am trying to achieve.

 

I have started with a Chamfer tool with the following settings:

 

45xD

Set Chain 1 – Standard selected 3 sides,

 

I have also tried Rule based and selecting Partial loop but the model fails to generate when I exiting the sketch.

 

Hope you can help with some pointers please as I am new to proE coming from a SW background. Thanks in advance for your help.Publication1.jpg

Hi Mark,

Looks like a candidate for a Sweep to me (in WF4 it would be a Variable Section Sweep with the option "Constant Section" selected... not sure what that's become in Creo).

Sketch your cutter path, then create a Sweep and select the path, then sketch the section within the Sweep - it should just be a triangle.

HTH!

Re: Help need with odd Chamfer /Pocket feature

Yep, this is a great place to use sweep. It will let you control your intended tool path as well.

If you insist on using the chamfer, however, you will need to make the recess to the shape of the tool-path and then add the through hole after the chamfer.

hi,

below i have added two images, if that is what you are looking for then you have to use the swept blend option and two guide curves. the cross section is triangular.

Go ahead and mark the answer as correct. Great to hear it!

Re: Help need with odd Chamfer /Pocket feature

in my last post i had shown two jpegs shwoing the swept blend option to put the cut.

well in pro/engineer also u can use only the chamfer option to get that particular cut. see the image below.chamfer.JPG

in chamfer select the detail option before selecting the edge and then select only the circular edge..you would get the desired result.

Re: Help need with odd Chamfer /Pocket feature

Actually, looking at the geometry, and imagining how it would most likely be cut, I'd say a simple revolved cut would be the most accurate and easiest, using the axis of the cylinder on the end there. Most likely (cheapest) the machinest went in there with a simple chamfer tool and plunged to the correct depth, or interpolated a circle. I don't think there's a need for a sweep etc.

Re: Help need with odd Chamfer /Pocket feature

Looking at the original input (lower right image), there is an obvious elongation of the chamfer path. I think the discussion morphed into a lesser "compromised" solution. As a matter of fact, the chamfer appears to blend tangent to the center "through" hole.

I hate seeing this when the modeling tool is more than adequate to do the job correctly.

Re: Help need with odd Chamfer /Pocket feature

Well, when I open the attached picture, they look compressed left-to-right. What looks like a circle in the small view gets highly elliptical when you open the pic. You can tell by the fact that even the cylindrical portion in the guy's hands looks elliptical, even the other views look elliptical. Without the part in hand this is one of those things that's hard to pin down.
