cutting a cam

I'm stumped.

Take a cylinder with a hole through the center. Plunge an endmill
into the cylindrical surface radially, then do a helical cut out
of the flat end of the part by turning the part and moving the
endmill along the axis of the cylinder. On the initial plunge,
the centerline of the tool is right on the flat end of the
cylinder.

The problem I'm having is getting the helical cam ramp face to be
tangent to the initial plunge hole. It's not as geometrically
simple as I thought it would be, having done other similar things
in the past.

Any help appreciated.

your link is to a word doc.

 

must have jumped the gun

 

i can't post a solution. shoot me an email with your address and i'll send
to you.

 

Link works for me. Are you really getting a word doc?

Oh, you're the one asking for the old version of my Tools, Options
doc. Let me look again and see if I can't find it. I think I
deleted the old version.

Ok, I'll trade you for that tools, options thing.

Take the underscores out of my email address.

Thanks for your help, I'm interested to see what you did.
