I am having an difference in opinions. We have an old blueprint of a cam. We need to make a master for the cam. The drawing shows the cam being cut with the dimensions of the profile being off the center of a cutter.
Others that I talk to say that the master must be built using the cutter specified in the drawing.
I say we can subtract half the cutter width and use whatever size end mill we want. In a cam system we could shrink the drawing by a percentage, offset it or something to that matter.
If I am not correct could someone please explain why? The agruement is that the dwells and rises will not be the same without using the exact cutter specified. |
