Abstract
A cutting insert for chipforming machining of workpieces is of the type comprising a rake face and a clearance face. At least one cutting edge is formed by the transition between the rake and clearance faces. The cutting edge is intersected by depressions extending along the rake face. The greatest dimension of each depression in a direction parallel to its associated cutting edge is greater than the distance between adjacent depressions.
Claims9
A cutting insert for use in the chipforming machining of workpieces, said insert comprising a rake face and a clearance face, at least one cutting edge formed by the intersection of the rake and clearance faces, said cutting edge being intersected by spaced depressions extending along said rake face, the depth of each depression initially increasing in a direction away from said cutting edge and thereafter decreasing in said direction.
A cutting insert for chipforming machining of workpieces, said insert being of the type comprising a rake face and a clearance face, at least one cutting edge formed by the transition between the rake and clearance faces, said cutting edge being intersected by depressions extending along said rake face, the improvement wherein the greatest dimension of each depression in a direction parallel to its associated cutting edge is greater than the distance between adjacent depressions, said rake face provided with a planar land situated along the cutting edge, the width of the planar land decreasing in the direction from a corner of the insert towards the center of the cutting edge.
