END MILL FOR ORBITAL DRILLING OF FIBER REINFORCED PLASTIC MATERIALS |
摘要 |
<p>A center or non-center cutting end mill (10) for orbital drilling of fiber reinforced plastic (FRP) materials includes a shank (12), a neck (14), a cutting head (16)and two or more flutes (36, 38). The end mill (10) has a tool geometry with the following features: a dish angle (28) between about 2 degrees to about 6 degrees; a helix angle (44) between about 5 degrees to about 18 degrees; an end teeth radial rake angle (46) between about 0 degrees and about 15 degrees; a peripheral teeth radial rake angle (47) between about 8 degrees and about 16 degrees; a gashing axial rake angle (48) between about 3 degrees to about 10 degrees; and a primary clearance angle between about 10 degrees to about 18 degrees. The end mill is made from a tungsten carbide substrate with cemented cobalt and a diamond coating.</p> |
