1. Increasing the corner radius improves the surface finish.

2. Increasing the corner radius improves cutting edge strength.

3. Increasing the corner radius too much increases the cutting resistance and causes chattering.

4. Increasing the corner radius decreases flank and rake wear.

5. Increasing the corner radius too much results in poor chip control.
