I need a formula that calculates an angle for an apparent radius of a cut using a standard endmill, let me explain what I need.
When an endmill is exactly 90 degrees from the work piece the mill creates a flat pass, however as you angle the endmill a radius forms, the closer you are to 90 degrees the bigger the radius. When the end mill is at 0 degrees or parallel to the work piece the radius is that of the endmill.
My problem is that I have a 1" endmill and I need to create a 2" radius length wise in a 3/4" x 3/4" x 6" bar, so I need the formula described above to know the angle at which I should mill.
Any help would help.
