The document pretty much has everything a CNC hobbyist would want to know about the use of endmills from types, how to sharpen, cutting fluids, work materials, feed rate etc. Only bits which are of little use are pages 77 to 89 relating to the development of a multipurpose endmill.
I've opted for buying bulk lots of 10 of both 2 and 4 flute endmills in ball nose and standard. 2 flute for roughing, as suggested by other members, and 4 flute for finishing. |
