Japanese Patent JP2007532332

A

This invention relates to a cutting insert (14) comprising a cutting portion (24) and a locating portion (26). The cutting portion comprises a cutting edge (28) formed at the intersection of a rake surface (30) and a relief surface (32). The cutting insert (14) further comprises an upper surface (34), a lower surface (36) and a peripheral side surface therebetween, wherein said peripheral side surface comprises opposing forward and rearward surfaces (38, 40) and opposing side surfaces (42) extending between the forward and rearward surfaces (38, 40). The relief surface (32) is located in the forward surface (38) and the rake surface (30) is located in the upper surface (34). The locating portion (26) extends downwardly from the cutting portion (24) away from the upper surface (34). Said locating portion (26) comprises opposing forward and rear locating surfaces(44, 46) wherein the rear locating surface (46) is located in the rear surface (40) wherein the forward and rearward locating surfaces (44, 46) converge downwardly. The rear locating surface (46) is located in the rear surface (40) and the forward locating surface (44) is located in the lower surface (36). A lower locating surface (48) is located in the lower surface (36) and opposes the upper surface (34) and extends between the forward surface (38) and the forward locating surface (44). The lower locating surface (48) is characterized in that in a side view of the cutting insert (14) the rear surface (40) is straight.
