machining - How do I manufacture a fillet? - Engineering ...

4. This answer is not useful. Show activity on this post. On a mass manufactured part, one solution is to cast the piece and shape the die (with an inside fillet) to form an outside fillet. Of course, if you want your casting to have an inside fillet, you'll need an outside fillet on your die.

How to Machine Square Corners with CNC Milling - Get It Made

A smaller cutting tool requires the CNC milling machine to run at a slower speed and takes longer to remove material. Also if the milled pocket is deep, a larger stronger cutting tool will need to be used. This means a larger radius would be required. A rule of thumb is to keep the corner radius greater than ⅓ cavity depth.
