- the cutting tool 100 comprises a tool holder 102 and a cutting insert 112.
- the tool holder 102 has an insert pocket 104 formed in a front end 106 thereof.
- the insert pocket 104 has a longitudinal main axis M extending in a forward to rearward direction Dp, D R , and a lateral pocket axis S.
- the tool holder 102 has longitudinally extending opposite first and second side surfaces 108, 110, and top and bottom surfaces 144, 154 extending therebetween.
- the insert pocket 104 opens out to the top surface 144.

- the insert pocket 104 has a forward clamping portion 124 and a rear clamping portion 128.
- the forward clamping portion 124 is coupled with the second side surface 110, located forward of the pocket axis S, and the rear clamping portion 128 is coupled with the first side surface 108, located rearwards of the pocket axis S.
- the forward clamping portion 124 has a longitudinally extending forward abutment surface 126.
- the rear clamping portion 128 has first and second rear abutment surfaces 130, 132, angled relative to one another and converging towards the pocket axis S.
- the first and second rear abutment surfaces 130, 132 may be spaced apart from one another by a non-abutting holder surface 131.
- the non-abutting holder surface 131 may be convex when viewed in a top view.
- a threaded pocket screw bore 150 passes through the insert pocket 104 along the pocket axis S.
- the insert pocket 104 also has a pocket abutment surface 146.
- the pocket abutment surface 146 may be parallel to the top surface 144 of the tool holder 102, and spaced apart therefrom by a pocket height H ( Figure 7).
- the first and second rear abutment surfaces 130, 132, and the forward abutment surface 126 may extend substantially perpendicular to the top plane T.
- the second rear abutment surface 132 may be substantially perpendicular to the first rear abutment surface 130, for example, as depicted in the top view of Figure 5.

- the first rear abutment surface 130 may extend substantially parallel to the first side surface 108.
- the forward abutment surface 126 may extend substantially parallel to the first rear abutment surface 130.
- the cutting insert 112 is S-shaped, having a longitudinal first axis I and a lateral second axis L.
- the cutting insert 112 may be indexable, exhibiting 180° rotational symmetry about the second axis L.
- the cutting insert 112 has two end surfaces 114 and a peripheral surface 116 extending therebetween.
- Two opposite cutting portions 118 are formed along the cutting insert 112, and a central clamping portion 120 is located therebetween, arranged along the first axis I.
- Each cutting portion 118 has a cutting edge 122.
- an insert screw bore 152 passes through the clamping portion 120 along the second axis L.
- the clamping portion 120 of the cutting insert 112 has an insert abutment surface 142, located on one of the end surfaces 114.
- the peripheral surface 116 of the cutting insert 112 has two opposing side flanks 134, each side flank 134 defining an insert side plane P, located on opposite sides of the second axis L.
- the insert side planes P are parallel to one another and are spaced apart by an insert width W ( Figure 5).
- the insert width defined by the side flanks 134 extends in a direction perpendicular to an imaginary plane defined by the longitudinal first axis I and the lateral second axis L.
- the two opposing side flanks 134 extend in opposite directions along their associated cutting portions 118, from the cutting edges 122, and partially along the clamping portion 120.
- the side flanks 134 extend longitudinally from the cutting edges 122, in opposite ones of the forward direction Dp and the rearward direction D R .
- a recessed clamping corner 136 is located following each side flanks 134, i.e., in a direction away from the respective cutting edge 122.
- Each clamping corner 136 has first and second clamping surfaces 138, 140 (located adjacent the respective side flank 134), which are angled relative to one another and converge towards the second axis L.
- the first and second clamping surfaces 138, 140 may be spaced apart from one another by a non-clamping insert surface 139.
- the non-clamping insert surface 139 may be concave (i.e., in a top view), forming the closest point of approach on the peripheral surface 116 to the second insert axis L around which the cutting insert 112 has 180° rotational symmetry.
- the cutting tool 100 is moveable between an assembled position (e.g., Figures 1 and 3) and a disassembled position (e.g., Figures 2 and 4).
- the cutting insert 112 In the disassembled position, the cutting insert 112 is separated from the tool holder 102.
- the cutting insert 112 is retained in the insert pocket 104, for example with a clamping screw 148.
- the clamping screw 148 passes through the insert screw bore 152 along the pocket axis S and threadingly engages the pocket screw bore 150 to fasten the cutting insert 112 to the insert pocket 104.
- the pocket axis S may pass slightly rearwards of the cutting insert's second axis L, i.e., along the main axis M, in order to retain the cutting insert 112 with a rearward tightening.
- first and second clamping surfaces 138, 140 of one of the clamping corners 136 i.e., adjacent one of the side flanks 134 and recessed from the insert side plane P
- first and second rear abutment surfaces 130, 132 respectively.
- the first clamping surface 138 of the other clamping corner 136 i.e., adjacent the other side flank 134
- the insert abutment surface 142 abuts the pocket abutment surface 146.
- neither of the side flanks 134 of the cutting insert 112 abuts the tool holder 102, and hence both side flanks 134 are considered non-abutting side flanks 134.
- Both of the second clamping surfaces 140 are located longitudinally between the first clamping surfaces 138. This provides further stability in retaining the cutting insert 112, when the two first clamping surfaces 138 are abutted against the insert pocket 104, and the angled second clamping surface 140 is located longitudinally therebetween.
- the second clamping surface 140 of the clamping corner 136 which is close to the forward clamping portion 124, does not contact the forward clamping portion 124 ( Figure 7).
- the cutting insert 112 is clamped in three locations about the second axis L against the insert pocket 104, namely, in the forward abutment surface 126, and the first and second rear abutment surfaces 138, 140.
- both of the side flanks 134 of the cutting insert 112 may remain free from abutting the tool holder 102, as it is not required to obtain another location of abutment between the cutting insert 112 and the insert pocket 104.
- the abutment locations of the cutting insert 112 are spaced apart from its cutting edges 122. Thus, any force or pressure applied at the abutment locations due to clamping or cutting operations, does not affect the cutting edges 122.
- the cutting edges 122 are not subject to forces originating in the clamping of the cutting insert 112, and are less prone to breakage due to such forces, thereby increasing the durability of the cutting insert 112. Further, if one of the cutting edges 122 is damaged during cutting operations (e.g., cracked or broken), the cutting insert 112 may still be indexed and clamped in the insert pocket 104, and the other cutting edge 122 may be further employed in cutting operations.
- the cutting portion 118 which is close to the forward clamping portion 124, extends forward of the tool holder 102.
- This is apparent, for example, in a bottom view of the assembled cutting tool 100, taken along the pocket axis S, as depicted in Figure 6.
- the first axis I of the cutting insert 112 may coincide with the main axis M of the tool holder 102. This is apparent, for example, in the top view of Figure 5, and the front view of Figure 9 (taken along the main axis M).
- At least one of the side flanks 134 of the cutting insert 112 is flush with a respective one of the side surfaces 108, 110 of the tool holder 102. This may be required when employing the invention in machines with limited space or multiple shanks placed in proximity to one another, which may also limit the access to the cutting tool 100.
- both of the side flanks 134 are flush with both of the side surfaces 108, 110 of the tool holder 102. However, it may be that only one of the side flanks 134 will be flush with the respective one of the side surfaces 108, 110.
- the clamping screw 148 is fastened to, or loosened from the pocket screw bore 150, respectively.
- the clamping screw 148 may not have to be completely extracted from the pocket screw bore 150, for the cutting insert 112 to be mounted into the insert pocket 104, or removed therefrom. Instead, it may be required to partially loosen the clamping screw 148, while keeping it threadingly engaged with the pocket screw bore 150 to a certain extent (e.g., Figures 2 and 4).
- the insert screw bore 152 is designed to allow the cutting insert 112 to pass over the head of the clamping screw 148 in particular orientations.
- the cutting tool 100 shown in the accompanying drawings is a Swiss type cutting tool, with the tool holder 102 having a rectangular lateral cross section, as depicted in the front view of Figure 9, taken along the longitudinal main axis M.
- the invention is in no way whatsoever restricted to the cutting tools of the type used for Swiss-type automatic machines (e.g., lathes), but is applicable to many types of cutting tools wherein a cutting insert is to be secured to an insert pocket.
- the cutting tool 100 may be a different kind of cutting tool, with the tool holder 102 having a non-rectangular cross section, while still employing the features of the cutting insert and insert pocket according to the present invention.
- the abutment locations of the cutting insert 112 are on the peripheral surface 116 thereof, except for the insert abutment surface 142.
- any abutment or clamping structures such as protrusions or depressions, on the insert end surfaces 114, and correspondingly on the pocket abutment surface 146.
- the height of the cutting insert 112 in the clamping portion 120 i.e., the lateral distance between the end surfaces 114
- the manufacture of the cutting insert 112 is simplified, for example, when the cutting insert 112 is formed by pressing of cemented carbide (e.g., tungsten carbide), and subsequent sintering thereof.
- the manufacture of the cutting insert 112 is made easier by simplifying the mold in which the cutting insert 112 is press-formed.
- the insert width W is made substantially similar to the width of the tool holder 102, namely the distance between the side surfaces 108, 110. If either one of the side flanks 134 were abutted against the tool holder 102, it would mean that the insert width W is smaller than the width of the tool holder 102.
