INTRODUCTION TO MACHINING 4. EXERCISES
[mm]; the largest tool diameter to machine the "pocket" would be 20 [mm]. The step around the outside edge can be cut with any tool with a diameter considerably larger than 10 [mm]. Use a face-mill to reduce the height of the part to 30 [mm]. Therefore: use a 20 [mm] diameter, centre-cutting, end-mill (at least 4 flutes) and a face mill.
