摘要： The invention relates to a method for wire cutting of a material (200), wherein a cutting wire is advanced (102) into the material (200) by causing said wire to scroll in such a way as to progressively cut the material, the method being characterised in that it comprises: - the measurement of a force (F) applied by the wire (102) on the material (200) as a function of time, - the measurement of the advancement of the wire (102) in the material (200) as a function of time, - the determination, as a function of said force and said advancement of the wire, of a variable (EF) characterising the state of the wire cutting and, - servo control of at least one cutting parameter through changes in said variable (EF) so as to reduce the rate of wear of the wire and/or to reduce the risk of breaking of the wire. The invention also relates to a device for wire cutting allowing implementation of said method.

摘要： The invention relates to a system for measuring a zone of separation in a substrate. This system (2) for measuring the propagation of a zone C of separation between a first portion (4) and a second portion (5) of at least one substrate (6) comprises: a module (10) for emitting at least two incident beams Fi each of which illuminates a separate point on the substrate (6), the at least two incident beams Fi being able to pass through the first portion (4) and the zone C of separation and meet the second portion (5) in such a way that each of them generates at least one first emergent beam Fe originating from the interface between the first portion (4) and the zone C of separation, and at least one second emergent beam Fe originating from the interface between the zone C of separation and the second portion (5); a detecting module (8) for detecting light intensity values resulting from interference between the first and second emergent beams Fe; and a computer (11) for determining the conditions of the propagation of the zone C of separation.

摘要： The cutting wire (100) has an outer surface with roughness formed by abrasive grains (103) having a given mean diameter Dg. The monitoring method includes the following steps: emitting (E0) a light beam (FL) defined by two parallel planes; moving (E1) the wire (100) through the light beam (FL) in a linear fashion, the angle between the wire (100) and the planes of the beam (FL) being comprised between 85° and 95°, in particular between 88° and 92° and more particularly equal to 90°; and, at consecutive acquisition times during the movement of the wire through the light beam, acquiring (E2) an optical signal that is formed from the emitted light beam and is partially interrupted by the wire, in a wire analysis window having a width of between Dg/2 and 4xDg, and determining, from the acquired optical signal, an apparent diameter value of the wire.

摘要： A method for refurbishing a partially used diamond wire is provided. The method includes depositing a binder on the partially used diamond wire (202, 634). Further, a diamond wire (100, 400, 500) for sawing hard and brittle materials is provided. The wire includes a core wire (150) and a coating, wherein the coating comprises diamond abrasive grits and a binder material, wherein the binder material comprises an initial binder (120) and a subsequent binder (320). A diamond wire saw device (700) for sawing hard and brittle materials includes such a diamond wire and a diamond wire usage stage determination system (760).

摘要： In the method, the wire (1) is driven in translation in at least one direction (F2) and, during its displacement in translation (F2), it penetrates into the piece to be cut (2) via a penetration face (20A) of said piece (2). According to the invention, a cushioning layer (9A) is positioned opposite the penetration face (20A) of the piece to be cut (2) such that, before penetrating into the piece (2), the wire (1) passes through the cushioning layer (9A). If the wire (1) is driven in translation in an alternating back-and-forth motion, and penetrates into the piece to be cut (2) in alternation via two opposite penetration faces (20A, 20B), two cushioning layers (9A, 9B) are respectively positioned opposite the two penetration faces.

摘要： The method involves: a. a step of causing the wire (1) to move b. concomitantly, a step of bringing the wire (1) and the workpiece (3) into contact so as to machine at least a groove in the workpiece (3), c. a vibration-inducing step during which the wire passes through at least one reservoir (8A, 8B) containing a transmission fluid to which vibrations produced by ultrasound are restituted, said reservoir being situated in the direct vicinity of the workpiece (3), so as to apply to the wire (1) vibrations which are transmitted into the groove. The reservoir of transmission fluid is formed by a cavity formed in a sonotrode (7A, 7B).
