Definitions
- the present invention relates to the clamping of removable cutting chips on a tool holder, such as for example a drill.
- a removable cutting insert is pressed against the bottom of a tool holder housing by a clamping screw freely passing through a central hole in the cutting insert to engage a tapped hole in the bottom of the housing .
- this play is found as uncertainty in the framing of the cutting insert on this bottom.
- the workpiece and vibrations are likely to apply a torque to the wafer around the clamping screw.
- the housing has a flat side wall, and even in general two, respectively longitudinal and axial with respect to a general axis of the tool holder, serving to support the corresponding flat side faces of the insert, to form, with the bottom, a trihedron for receiving a corner of the plate, thus blocked in translation and in rotation.
- the wafer therefore has generally two large rectangular parallel faces, front and rear, connected by four side s' anes faces defining four straight edges with large front surface, two successive lateral faces serving as a support of framing, the other two side faces can perform this function if the plate is reversible.
- the housing is open axially at the end and / or laterally to leave one of the above edges accessible, as a cutting edge.
- the cutting edges must, however, for certain applications, have, in plan view, an angular profile, that is to say that one side of the classic rectangle delimiting the large anterior face is then replaced by two successive segments.
- the cutting edge comprises an end section in bevel or cutaway, folded towards the next edge.
- the cutting edge on the opposite side therefore has the same angular shape.
- this shape is determined by the intersection between the large anterior face and the respective lateral support face, each of the lateral support faces must therefore in principle be provided in the form of two mutually inclined flat zones, in plan view of the brochure.
- the classic rectangle limiting the large front face is replaced by a hexagon and this hexagonal shape applies to all the sections parallel to the large faces, that is to say for the framing support flanks.
- the periphery of the receiving trihedron of the wafer initially defined by two perpendicular side walls representing half of the periphery of the wafer, is now defined by four side surfaces which, admittedly, always represent half of this periphery, but now limit the periphery of the bottom of the housing according to a less angular shape, that is to say with sections or facets of generally rounded appearance.
- the side walls are poorly resistant to the support of the plate, which tends to slide there by a wedge effect increased by the obliquity above, that is to say with an amplification of force.
- the problem of precision of their positioning and their maintenance is more acute, because they are used to perform precision machining thrust.
- bearing faces having several facets it often happens that the user places the plate in an incorrect angular position, because the generally rounded shape of the framing walls around the housing results in the fact that they tolerate improper mounting.
- the user can then perform a screwing, with anticipated jamming, but this screwing has no cropping effect, so that the machining of the workpiece is imprecise and, moreover, the insert, not fully plated on the bottom of the housing, can, with vibrations, free itself from the screw, not fully tightened, and damage the workpiece.
- the tool holder and insert may also be damaged.
- Conventionally, to resist the parasitic torque we cut, on the lateral faces, grooves extending in the direction of the thickness of the wafer, so that the area closest to the large rear face constitutes a base for fixing forming a toothed wheel, with which mesh the walls of the housing, by presentation of a corresponding grooved shape.
- This therefore consists in replacing a perimeter of a plate delimited by a series of profiles of monotonic, flat or rounded lateral surfaces, by a perimeter generally of the same shape but wavy, that is to say non-monotonic, therefore of greater length, which thus has an increased number of accordion facets, therefore having a radial extension, compared to the clamping screw, which is more marked.
- a solution is not suitable, due to the risk of incorrect positioning described above.
- the present invention aims to propose a solution to this problem of positioning a wafer in the housing.
- the invention firstly relates to a reversible cutting insert comprising a part of front layer, of cutting head, comprising mutually inclined anterior perimeter lateral faces and delimiting, with a large anterior face, a front view profile formed by a number of mutually inclined cutting edges according to said profile, and a posterior layer portion, constituting an anchoring base on a tool holder, comprising lateral faces of posterior periphery at least some of which are framing bearing faces on the walls of a housing of the tool holder, characterized by the fact that the rear periphery has a number of lateral framing support faces less than the number of cutting edges.
- the lateral framing support faces may be planar or may define a curved periphery, the curvature possibly being variable on the same lateral framing support face, the lateral framing support faces being concave or convex.
- the successive lateral faces of the framing support can be connected at respective angles less than 180 degrees, thus defining a said posterior periphery with orientation varying monotonically, that is to say that the successive segments of periphery "s 'roll up' to circle the perimeter, always deviating on the same side.
- the lateral framing support faces are generally frustoconical.
- the front layer part may have a shape of a pyramid trunk having rising edges aligned with rising edges of the posterior layer portion.
- the part of the anterior layer is delimited by two sections of nested pyramids, with different conicities.
- the large front face may in particular generally have a shape of a parallelogram, some of them, among pairs of lateral faces of consecutive framing support, being for example mutually inclined at an angle advantageously between 65 and 85 degrees.
- the invention also relates to a tool holder for a cutting insert according to the invention, the tool holder comprising a housing comprising a bottom, associated with means for clamping the insert, and lateral walls for receiving the rear flanks d 'framing support of the wafer, characterized in that the housing is arranged to receive in support a first determined number of rear flanks for framing the framing of the wafer and to leave accessible a second determined number, greater than the first number, front cutting edges of the insert determined by as many lateral faces of mutually inclined front periphery.
- the walls of the housing can, for some, be flared relative to the bottom, in order to cooperate with oblique sides.
- FIG. 1 is a perspective view of the drill, carrying, diametrically opposite, two such plates, one of which shows an anterior face of one
- FIG. 2 is an oblique perspective view showing a rear face and two lateral faces of one of the plates, in the inverted position .
- the tool holder of FIG. 1 is here a drill 20 of axis of rotation 21 presenting very schematically, seen from the drawn front end, four angular sectors of approximately 90 degrees each, two of these corresponding to two recesses respective due to grooves with a slightly helical axial extension, in order to leave two substantially identical and axially opposite housings 30, 40 released, formed in the other two sectors.
- the housing 30 has a bottom 32, extending in an axial plane and parallel to a radial direction, but without however passing through the axis 21.
- the housing 30 thus forms a bottom-cavity 32 lowered relative to a radius limiting the sector considered, that is to say the radius representing the front end of one of the two surfaces limiting the groove considered.
- This lowering, determining the depth of the housing 30, corresponds to a thickness value of a cutting insert 10.
- the housing 30 is limited by a longitudinal side wall 34, located near the axis 21, and by a rear side wall 35, very approximately radial.
- the plate 10 is here in section in parallelogram, so that the rear side wall 35 has a radially outer edge which is axially more advanced than a corner 39 of junction with the longitudinal wall 34, corner 39 therefore close to the 'axis 21.
- the housing 30 is here with walls 34 and 35 slightly flared therefore each forming, with the bottom 32, an angle slightly exceeding 90 degrees, because the plate 10 has a truncated pyramid shape.
- the cutting insert 10 generally has the shape of a block, and it is precisely here a micro-insert of a few millimeters on the side, having, in this example, a distance of approximately 5 mm between so-called main neighboring corners, like the plurality of here four active corners referenced 130, 140, 150, 160, that is to say at an angle closer to 90 degrees than to 180 degrees.
- the plate 10 comprises two main faces opposite here substantially planar and parallel, namely an active front face 1, with cutting or cutting edges, and a rear face 2, connected by a series of four lateral faces constituted by two opposite sides 3, 5 respectively called front and rear, also called transverse, or radial, and by two opposite longitudinal sides 4, 6, that is to say axial.
- the number of flanks could be different in another example.
- the rear face 2 is a bearing face on the bottom 32 and the front face 1 is then flush with the top of the housing 30, that is to say occupies a substantially radial position.
- the plate 10 having however a symmetry, exposed later, with respect to a proper geometric axis directed according to its thickness, there are two possible mounting positions, mutually different from 180 degrees, so that the qualifiers "front” and "rear” are only valid for these figures.
- the axis 21 of extension of the drill 20 constitutes one.
- the plate 10 has a face turned in the instantaneous tangential direction of its rotary movement, namely the active face 1.
- the faces 1 and 2 are respectively called “anterior” and “ posterior “with respect to this tangential direction, and not” front “and” rear “.
- Figure 1 shows that the plate 10 is traversed, according to its thickness, by a central fixing hole 90, determining the above geometric axis, hole in which passes freely a clamping screw 41 cooperating with a threaded hole 31 formed in the bottom 32 of the housing 30.
- any other method of clamping may however be provided as a variant.
- the longitudinal sides 4 and rear 5 respectively of the plate 10 are in abutment on the respective walls 34 and 35 of the housing 30.
- the plate 10 is also locked in rotation on the bottom 32.
- the profile of the front face 1 that is to say its contour in front view along the axis of the fixing hole 90, profile visible in Figure 1 and better discernible in Figure 2, is not perfectly square or rectangular, but it has two particularities.
- each cutting edge 13 to 16 is thus formed of a pair of first and second segments successive 13a and 13b, 14a and 14b, 15a and 15b, 16a and 16b, each pair of such segments forming the two branches of a "V" opened here at about 170 degrees.
- the first segments 13a, 14a, 15a, 16a are here shorter than the second segments 13b, 14b, 15b and 16b and constitute a cutaway extension thereof, that is to say slightly folded towards the second neighboring segment.
- the differences between the overall directions of extension of two successive cutting edges 13, 14, 15, 16 are different from 90 degrees, alternating around this value at each of the four main corners of the profile, 130 , 140, 150 and 160, defined at the successive connections of the cutting edges 13 to 16.
- the cutting edges 13 and 14 are generally mutually inclined at 105 degrees in this example, as are the cutting edges 15 and 16.
- the opposite cutting edges being generally parallel, it follows that the cutting edges 14 and 15 delimit an angle of 75 degrees, just like the cutting edges 13 and 16.
- the plate 10 can be fictitiously divided into two functional parts, namely a layer constituting an anterior part 1A, for cutting or cutting a workpiece, and a layer 1B constituting a posterior part forming a fixing and framing base in the housing 30.
- the anterior layer 1A bounded by the anterior face 1, has, from the front, the above profile with eight sides, that is to say the four pairs of segments 13a and 13b, 14a and 14b, 15a and 15b, as well as 16a and 16b.
- the rear part 1B has only a smaller number, compared to the eight sides, of the lateral support and framing faces.
- the rear part 1B has four such lateral faces 3B, 4B, 5B and 6B, that is to say a number which is equal to the number of front edges 13 to 16.
- the rear part 1B here has a slightly frustoconical shape , precisely in truncated truncated pyramid with rising edges 130B, 140B, 150B and 160B, separating the successive posterior lateral surfaces of flank respectively 3B, 4B, 5B and 6B, here plane,
- the extensions of the edges rear risers 130B, 140B, 150B and 160B pass through the front main corners 130, 140, 150, 160. Because, in the front face 1A, the segments 13a and 13b, 14a and 14b, 15a and 15b, as well as 16a and 16b, extend laterally outward relative to the parallelogram defined by the four main front corners 130, 140, 150 and 160, it follows that the front part 1A has, around the extension fictitious ment of the pyramidal shape of the rear part 1B, a bead or skirt of material supporting the eight cutting segments above.
- the front part 1A is substantially in the form of a truncated pyramid with eight sides, the base of which is limited by the four pairs of segments 13a and '13b, 14a and 14b, 15a and 15b, 16a and 16b, and which rise by presenting four so-called main anterior rising edges 130A, 140A, 150A and 160B which are here the extension of the posterior rising edges 130B, 140B, 150B and 160B, as mentioned above.
- Each edge such as for example the edge formed by the segments 13a and 13b is thus supported by two surfaces forming a beak, that is to say a kind of cornice with lateral extension, constituting a projection of the profile, in front view. , of the anterior face 1.
- the secondary edges such as the edge 131A for example, have here an extension limited to less than half, here about a third, of the thickness of the plate 10, so that 'They extend at a relatively high angle, for example greater than 30 degrees, here about 45 degrees, relative to the associated side face 3B or the like.
- the corresponding side face 3B can thus be further back from a workpiece, thus offering an increased volume of chip clearance.
- the spouts like 13a and 13b could have more than two such cutting edges, for example if the secondary front corner 131 was truncated.
- the anterior secondary rising edges 131A, 141A, 151A and 161A therefore determine a taper angle greater than that of the posterior part 1B and therefore also of the four main front rising edges 130A, 140A, 150A and 160A. Therefore, the front part 1A does not have exactly the shape of a segment of pyramid, but is formed by the union of two sections of overlapping pyramids, with different conicities. It will now be specified, with reference to FIG.
- the front anterior lateral surface 3A defining a section of the bead, consists of the two successive anterior flat lateral surfaces 3a and 3b, mutually inclined, respectively limited by the cutting edges 13a and 13b and separated by the anterior secondary rising edge 131.
- the trihedral thus formed constitutes a lateral cutting beak.
- the flanks 4 to 6 likewise have the pairs of homologous cutting segments 14a and 14b, 15a and 15b as well as 16a and 16b.
- the anterior lateral surfaces 3a and 3b come to cut the posterior lateral surface 3B along two respective straight lines 13c and 13d in V open towards the anterior face 1.
- the anterior part 1A has therefore, in this example, a variable thickness, and in particular zero at the level of the front main corners 130, 140, 150 and 160, where the bead cancels locally.
- the bead Over the thickness of the total periphery of the large anterior face 1, the bead thus forms four festoons, each in the form of a beak having a lateral overflow extension and a thickness which are maximum at the level of the secondary corners 131, 141, 151 and 161 of the beak point, and a minimum thickness, here zero, at the level of the main corners 130, 140, 150 and 160 where they are connected.
- the current thickness of the four nozzles on the total periphery defines a functional thickness of the front part 1A, and, by difference with the constant total thickness of the plate 10, determines a functional thickness of the rear part 1B.
- the front main corners 130, 140, 150 and 160 do not constitute the extension of the rising edges of the rear part pyramid 1B, that is to say that the front main rising edges 130A, 140A, 150A and 160A have a conicity independent of that of the posterior part 1B, for example equal to that of the anterior secondary rising edges 131A, 141A, 151A and 161A, to effectively define a trunk of the pyramid, or else so that the bead provides optimal support over the entire length of the eight segments 13a and 13b, 14a and 14b, 15a and 15b, 16a and 16b, while having a desired draft angle.
- the minimum thickness presented by the bead, at the main corners 130, 140, 150 and 160, is not zero.
- the posterior layer part 1B could form a sole of constant thickness, that is to say that the overflow V would no longer form a trihedron, but would retain its shape over the entire thickness of the anterior part. 1A.
- the radial rear side wall 35 of the housing 30 has a suitable shape, here flat, to receive as much support the front rear side surface 3B as a homologous rear rear side surface of similar shape and belonging to the rear flank 5, this who is the case of Figure 1.
- the longitudinal side wall 34 has the same kind of shape, adapted to cooperate with any of the rear parts 4B and 6B of the sides 4 and 6.
- the walls 34 and 35 s extend, substantially axially and approximately radially, in a rectilinear manner, in accordance with the two posterior flanks considered 4B and 5B or 6B and 3B, of support and framing of the posterior pyramid.
- a posterior rising edge coming from the main corner 140 homologous with the posterior rising edge 160B coming from the main corner 160, constitutes a kind of tooth having a good radial extension with respect to the axis of the fixing hole 90, and it thus offers a surface less inclined on a radius of the axis of the hole 90 than would be a tooth defined by two surfaces mutually inclined at 90 degrees.
- the walls 34 and 35 may also, as shown in FIG. 1, be provided, to each comprise, in the upper part of the housing 30, an area having a shape of a recessed V-shaped cavity in order to provide additional force. support by cooperation with the anterior flank zones 4A and 5A or 6A and 3A, even if this complement is less effective than for the posterior part 1B, with rectilinear flanks.
