Definitions
- the invention relates to a cutting element and a tool with at least one cutting element.
- the cutting surface of the cutting part is the surface on which the chip runs during the material removal process.
- the free surfaces are the surfaces that face or face the cut surfaces created on the workpiece.
- the cutting lines or one-dimensional structures in which the rake faces and the free faces intersect form the cutting or cutting edges of the tool. When viewed in a working plane of the tool, the so-called main cutting edges point in the feed direction, but the secondary cutting edges do not.
- the main cutting edges and secondary cutting edges meet the rake face on a cutting edge. It is often provided with a rounded corner or chamfer.
- the so-called tool angles are determined by the position or location of the surfaces on the cutting part relative to one another and are measured in the so-called tool reference system.
- the tool angles therefore characterize the geometry of the cutting part and are important for the manufacture and maintenance of the tools.
- the tool angles must be differentiated from the effective angles measured in the so-called active reference system for the representation of the machining process.
- a tool reference plane which is placed as perpendicular as possible to the assumed cutting direction by the cutting point under consideration, but is aligned to a plane, axis or edge of the tool, in the end mill of the axis of rotation, there is also a cutting plane that contains the cutting edge and one wedge measuring plane.
- the tool reference plane In the knitting reference system, the tool reference plane must be replaced by the knitting reference plane that is perpendicular to the knitting direction. is sought.
- the three levels of each of the two reference systems are perpendicular to each other.
- the most important angles for machining are the rake angle ⁇ , which corresponds to the angle between the rake surface and the tool reference plane, the wedge angle ß, which corresponds to the angle between the rake surface and the flank surface, and the clearance angle, which corresponds to the angle between the flank surface and the cutting edge plane.
- the sum of the three angles, ß and ⁇ is 90 °.
- the setting angle ⁇ which is measured between the tool cutting edge plane and the working plane in the tool reference plane
- the corner angle ⁇ which is measured between the cutting edge planes of related main and minor cutting edges in the tool reference plane.
- the angle of inclination ⁇ in the tool cutting edge plane is defined as the angle between the cutting edge and the tool reference plane.
- cutting elements or: cutting plates, cutting inserts
- the so-called cutting elements which have two or more cutting regions that are essentially identical or congruent to one another and can be used several times by turning or rotating relative to the carrier body, depending on the number of identical ones present To cut.
- the cutting edges are arranged according to a predefined rotational speed or n-fold rotational symmetry, whereby this symmetry means that the cutting part merges into itself when it is rotated by a predetermined rotational angle or an integral multiple of the rotational angle.
- a rotation angle of 180 ° is generally selected, with three cutting edges a rotation angle of 120 °, with four cutting edges a rotation angle of 90 ° etc., that is to say generally a rotation angle of 360 ° / n, n being the is the integer toughness of the symmetry.
- An indexable insert with an n-fold symmetry can be used n times by turning it before it is finally replaced. Depending on the application, very different forms of such inserts are known.
- indexable inserts with curved cutting edges of the tool are also known or also curved shape of the rake faces and open faces, as known for example from US 4,294,565 A, EP 1 075 889 A, DE WO 52 963 A, DE 99 56 592 A1 or EP 260 298 AI.
- a cutting insert for machining (or: finishing) for a milling tool is known with two mutually parallel flat surfaces or flat sides and cutting edges on the front flat side.
- Trapezoidal side surfaces are formed between the two flat sides, which make an acute angle relative to a normal plane to the flat side of the cutting insert.
- This inclination of the side surfaces allows a clearance angle in the case of an arrangement at a positive axial inclination angle, that is to say in the case of an inclination in the direction of rotation seen in the direction of rotation of the tool on the radial outside of the cutting insert.
- the front and rear flat sides have a polygonal shape with the same side lengths, in particular a square shape, that is to say four-fold rotational symmetry with four main cutting edges.
- the main cutting edges are shaped like a circular arc with a radius that is several times larger than the width of the front flat side of the cutting insert.
- This circular convex curvature of the cutting edges results in a corner drop x which is measured between an end point of the cutting edge and a tangent to the center point (d) of the cutting edge.
- convexly curved incisions are provided for attaching the insert to its seat on the tool body.
- this known cutting insert according to US 4,294,565 A it is not a corner region of the cutting plate that is used for milling or cutting, but rather the edge region of the square basic shape around the center of the cutting edge.
- a face milling cutting tool is known with several disposable cutting plates which are detachably fastened in cutting plate receptacles to an elongated main tool body.
- the disposable inserts are polygonal inserts which have a corner cutting edge provided in at least a part thereof, an arc cutting edge arranged on one side of the corner cutting edge at the front end part of the tool main body, and an outer cutting edge located on another side of the corner -
- the cutting edge is arranged on an outside of the main body of the tool, the arc cutting edge starting from the corner cutting edge on the front end part of the tool main body protrudes forward and the outer cutting edge starts from the corner cutting edge in the direction of an axis of the tool main body.
- the arc cutting edge has a fixed radius of curvature and thus a constant curvature.
- the corner cutting edge also has a fixed radius of curvature and thus a constant curvature.
- the radius of curvature of the corner cutting edge is smaller than that of the arch cutting edge.
- the outer edge is straight.
- DE 199 56 592 A1 discloses a cutting insert for ball track milling cutters with a main cutting edge which runs essentially in a radial plane and is to be arranged on the end face and a secondary cutting edge which runs predominantly axially to the rear and partially radially outward and is rounded off with a top view of the upper surface of the cutting insert Corner cutting edge at the transition between main cutting edge and secondary cutting edge with a radius, the secondary cutting edge having a radius which is significantly larger than the radius of the corner cutting edge and which is smaller than twice the milling cutter diameter for which the cutting insert is intended.
- the radii of curvature and thus the curvatures of the cutting edges are always constant.
- a cutting insert is known from EP 1 075 889 A1 with two opposing main cutting edges and two secondary cutting edges each adjoining the main cutting edges, the cutting edge angle being between 3 ° and 35 °.
- the main cutting edge is arch-shaped
- the secondary cutting edge is arch-shaped or straight and is tilted back with respect to the central axis of the cutting insert.
- This known cutting insert has two corner areas with the circular arc-shaped main cutting edges and thus a two-fold symmetry or double usability.
- a cutting insert with a three-fold symmetry or with three corner areas with main cutting edges and thus with three uses is also disclosed.
- Hitachi EP 1 260 298 A1 is considered the closest prior art for the subject of the application.
- This document EP 1 260 298 A1 discloses an exchangeable cutting insert for a cutting, rotating tool.
- the cutting insert has a square front flat side and a square rear flat side as well as a curved flank rich on the side surfaces between the front and the back flat side.
- This known cutting insert has a so-called positive-type shape, with an outwardly curved edge line between the front flat side and the flank area serving as the cutting edge.
- a positive type is called a cutting insert if it already has a clearance angle on the cutting edge for the cutting process.
- Each flank area has a flat-shaped area in the middle for fitting into the associated seat on the rotating tool body, which extends to the lower or rear flat side without touching the cutting edge.
- a major cutting edge which is formed by the outwardly curved edge hnee, extends circularly from its lowermost point to the periphery of the tool when the cutting insert is attached to the tool at a negative radial rake angle.
- the radius of the outwardly curved edge line is 0.6 to 1.6 times the diameter of an inscribed circle in the cutting insert and '11 mm to 15 mm.
- the invention is based on the object of specifying a cutting element which is further improved with respect to the cutting forces compared to the cutting element known from EP 1 260 298 A1 and a cutting tool with at least one such cutting element.
- the cutting element (or: insert, cutting insert) according to claim 1 comprises a first surface, in particular an end face, and at least one side face, the side face and the first surface meeting in an edge region and at least one cutting edge (or: cutting edge) being formed on this edge region ,
- each cutting edge is now essentially convexly curved with respect to the axis of rotation, such that the curvature of the cutting edge increases strictly monotonously in the predetermined direction of rotation about the axis of rotation.
- the strictly monotonous increase in the curvature means that the curvature at a second cutting point following a first cutting point in the given direction of rotation is always greater than the curvature at the first cutting point.
- the engagement length of the working or cutting edge ie its length in contact with the workpiece during cutting, is shorter than due to the increasing curvature of the cutting edges in the cutting element known from EP 1 260 298 A1.
- the effective cutting or cutting forces, the heat input and the tendency to vibrate are further reduced in comparison to EP 1 260 298 A1 and the service life is further increased.
- the cutting edge is effective in a region with little curvature or almost a linear course, which enables a minimal length of engagement and a high surface quality and smoothness of the surface in the workpiece or a good compensation of the feed marks and even at high feed speeds. Due to its increasing curvature, the cutting edge is also effective at large engagement depths, such as pre-finishing or rough machining, and allows greater engagement depths with the same outer dimensions of the cutting element or smaller dimensions of the cutting element at the same engagement depths as the cutting element known from EP 1 260 298 A1.
