Abstract
A slotting tool body includes a disc-like cutter portion including opposing forward and rearward cutter portion side surfaces and a cutter portion peripheral surface extending therebetween and a shank portion projecting rearwardly from the rearward cutter portion side surface. The cutter portion includes a number N of angularly spaced apart clamping portions, each having a peripherally disposed insert receiving slot. The cutter portion further includes a flexibility recess recessed in the forward cutter portion side surface and extending to each of the insert receiving slots. A cutting insert is releasably and resiliently clamped in each insert receiving slot to form a rotary slot cutting tool.
Claims28
A slotting tool body (22), having a body central axis (B) that defines opposite forward and rearward directions (DF, DR) and about which the slotting tool body (22) is rotatable in a rotational direction (R), the slotting tool body (22) comprising:
- a disc-like cutter portion (26) comprising:
- opposing forward and rearward cutter portion side surfaces (28a, 28b) and a cutter portion peripheral surface (30) extending therebetween;
- a number N of angularly spaced apart clamping portions (32), where N is an integer greater than 1, each clamping portion (32) having a peripherally disposed insert receiving slot (38) which opens out to the forward and rearward cutter portion side surfaces (28a, 28b) and the cutter portion peripheral surface (30);
- and
- a resilient clamping member (34) and a lower jaw member (36) which oppose each other and which are spaced apart by the insert receiving slot (38), the resilient clamping member (34) being configured to resiliently retain a cutting insert (24) in the insert receiving slot (38);
- and
- a shank portion (56) projecting rearwardly from the rearward cutter portion side surface (28b), the shank portion (56) comprising a shank peripheral surface (58) which extends circumferentially about the body central axis (B);
- wherein:
- the cutter portion (26) further comprises a flexibility recess (64) recessed in the forward cutter portion side surface (28a) and extending to each of the insert receiving slots (38).
