For example, to do a 14 hole, the depth of 12, drilling milling cutter is 12, how to do? Is not to make a hole, hit bottom?
Very simple ah, first a 11.5 deep bottom with 13 bits, and 12 mills with G03 go round a deep hole can be, if you can directly through hole with a drill.
Hole diameter 13.5 deep 11.5
If it is 2 or 3 blade drill cutter blade can directly tie the knife down, pay attention to the amount of feed is normal chip 50%. cut to a depth of 14 circular interpolation milling go round, another method is to do direct bottom hole drilling milling spiral milling cutter position. The premise of direct interpolation are to have the edge over center
