SQUARE-SHAPED CUTTING INSERT HAVING CURVED SECONDARY AND CORNER CUTTING EDGES, AND ROTARY CUTTING TOOL

Iscar, Ltd., Tefen (IL)

1. An indexable cutting insert (20, 120, 220), comprising:opposing upper and lower surfaces (22, 24) with a peripheral surface (26) and an insert axis (A1) extending therebetween,
the peripheral surface (26) intersecting the upper surface (22) to form a continuous upper peripheral edge (28), and including four insert side surfaces (30) alternating with four insert corner surfaces (32),
each insert side surface (30) intersecting the upper surface (22) to form a side cutting edge (40), and each insert corner surface (32) intersecting the upper surface (22) to form a curved corner cutting edge (42),
wherein each side cutting edge (40) includes a primary cutting edge (46) adjoining one of the corner cutting edges (42) at a first endpoint (N1) and a secondary cutting edge (48) adjoining another one of the corner cutting edges (42) at a second endpoint (N2),
wherein in a top view of the cutting insert (20, 120, 220) along the insert axis (A1):
the upper surface (22) is square-shaped with each of the four primary cutting edges (46) being straight, and the four primary cutting edges defining four sides of an imaginary first square (S1),
each primary cutting edge (46) is tangential to its adjoining corner cutting edge (42), and
each secondary cutting edge (48) is continuously curved and entirely located in a corresponding one of four imaginary quadrants (Q1, Q2, Q3, Q4) defined by two mutually perpendicular imaginary lines bisecting the imaginary first square's four sides, and
wherein:
each insert side surface (30) includes an insert side relief surface (50) intersecting the upper surface (22), and an insert side abutment surface (52) between the insert side relief surface (50) and the lower surface (24), and
in a cross-section taken in a second plane (P2) perpendicular to the insert axis (A1) and intersecting the four insert side abutment surfaces (52), the four insert side abutment surfaces (52) define four sides of an imaginary third square (S3).
