Here i will show you how to calculate Tool Engagement Angle using tool diameter and Width Of Cut (radial deopth of cut)
Lets first draw a pretty image that shows us everything we need.
- r: Radius of the cutter = Diamater /2
- a: TEA - Enagagement angle we are trying to find here
- WOC: Width of cut or RADIAL Depth of Cut
- r2: The difference between r and WOC, r=r2+WOC
Below we develop 2 formulas that allow us to find TEA and WOC
