Making parts fit together after machining

[Pearsonh001]

As anyone who machines parts knows, you have to create clearance In the corners of a pocket cut where parts fit together, b/c the Bit creates a radius that will not allow parts with a right angle edge to snap into the pocket cut. 

Is there any type of operations that would create this automatically based on the bit your using? 

Or does anyone have any good tips to preform this without manually going and adding clearance in every single corner? 

thanks!

There is an addin that I've used in the past that automatically adds "dog-bone" fillets into the corners, but it doesn't automate anything in the CAM workspace
