| 摘要 |
The cutting insert of the present invention has such shape that use of the same in a machining operation creates a greater than conventional surface pressure on the contact surface of the insert, such pressure causing an extremely thin, localized, area of the contact surface to attain an elevated temperature creating a flow layer therein. Such area reduction is effected by the formation on the contact surfaces of the notches inside of the cutting edge of the insert. |
