So I have a cam that I need to copy so that I can produce it on my cnc.
This cam is part of a timing device that lower and raises a table on a cardboard cutting and printing machine.
There is two cams that have follower "fingers" that ride on the outside.
It has a flat spot on it along with two different arcs. [ what we think is two arcs but maybe not]
So my question is... is there a easy way to measure the outside to get the arcs ["size and locations where they meet including the flat spot] that I can draw it up in cad.
I do have a brown and sharpe manual cmm machine with the reflex control. I have only had it for a couple months so still new to that machine.
The cardboard machine company who made it originally went out of business many years ago and the ordered replacement [ one in the pictures that Im coping] is $$$$$, hence why we are trying reproduce it.
The cams life span is around 10 years.
Tolerance spec-ed is +/- .003
