Abstract
A tangential cutting insert has a body with an operative front surface associated with upper and lower main cutting edges, side auxiliary cutting edges and corner cutting edges therebetween. All cutting edged have rake surfaces formed at the front surface and extending from their associated cutting edges in an inward direction of the cutting insert. The cutting insert has an imaginary reference plane passing through extremities of the cutting corner edges thereof. Each of the main cutting edges extends from its associated comer edges in an inward direction of the cutting insert away from the reference plane.
Claims17
A tangential cutting insert having a body with an operative front surface associated with upper and lower main cutting edges, each of said main cutting edges being connected by first and second corner cutting edges to respective first and second side auxiliary cutting edges, each of the main cutting edges side auxiliary cutting edges and comer cutting edges having a rake surface associated therewith in the front surface the rake surfaces extending along an entire circumference of the front surface and in an inward direction of the cutting insert, the cutting insert having an imaginary reference plane passing through extremities of the corner cutting edges thereof, wherein each of said main cutting edges extends from its associated corner edges in an inward direction of the cutting insert away from said reference plane.
A tangential cutting insert comprising:
- at least one operative front surface associated with upper and lower main cutting edges, the upper main cutting edge being connected by first and second comer cutting edges to respective first and second side auxiliary cutting edges, the lower main cutting edge being connected by third and fourth comer cutting edges to respective said first and second side auxiliary cutting edges, wherein:
- extreme points of the comer cutting edges define an imaginary reference plane on one side of which the cutting insert entirely lies,
- each of the main cutting edges extends from its associated comer cutting edges in a direction away from said reference plane, and
- each of the cutting edges has a rake surface associated therewith in the front surface.
