Chamfer Solid Question

[rwpmaster]

Hi everyone. 

Having an issue getting my chamfer to continue the rest of the way down this part. Can anyone offer some advice on how to fix the problem? I have included the file and the red lines are what I'm trying to chamfer.  I would like to save a set up on all these parts and have the chamfer in the model. Any help would be appreciated.

I recently had a part were the lead in would work but the lead out would cause it to stop short of the edge.  Playing with the sweep angle on the lead out would get it to work in some places and if I tried enough sweep angles it might have worked but simply turning off the lead out gave me what I needed.  With lead out off it still did a 90 degree lead out.  I'm at home right now so I can't look at your file to see if its the same problem I was having.

That is asking for a lot even out the most advanced CAD package. What about the transition into the top diameter? What are you thinking you want for a blend there? I have found it is best to solid fillet a shape like this and then use that to drive my chamfer sweep so I have to edges to work from. You also need to make the chamfer shape normal to the cut and not normal to the coordinate system. The chain that is going to do the work should be inline with the cut your trying to model. the last option would be to surface chamfer this. A lot of people are not aware the fillet surface option in Mastercam can also chamfer and some times of the best option when trying to do free form shape such as the one your trying to do.

Here is what a variable fillet look like look at the transitions and I think you will see where and why what your trying to do it not easy.
