Has anyone tried to chamfer a hole and then round over the top of the chamfer. I’m attempting to make a bowling ball shelf. I don’t want a sharp edge at the top of the chamfer cutting into the bowling ball. Yes, I could hand sand, but looking for a round over solution. My CNC 1/4 rad bit seems to leave a groove no matter how deep I cut or offset it from the edge. Any ideas appreciated.
How are you designing your work / generating your toolpath? With Fusion 360, you could actually radius the edge of the hole, and use a ball-nose bit to carve the radius. Not sure how to do it with other packages. Hope that helps - let us know what you find out!
What CAD/CAM application are you using? What is the diameter of the holes?
Use a Point Roundover Bit available at most bit suppliers. Here’s a version that I use:
vCarve pro with a 1/4 radius
Point round over.
@Wiremand I’m trying to understand your process, Dudley. You are cutting the hole, then chamfering with a v-bit, then using a point round over to round of the surface edge of the chamfer ??
You pretty much have it. I was thinking of cutting the hole last as the. Board is 1.5 inches and chamfering only. Down .75 inches Post
@Wiremand Does the bowling ball sit in this hole? If so, I believe that the moulding toolpath will do what you want.
