摘要:
A device for making through holes in ceramic slabs, comprising: a laser source (20), set up for emitting a laser beam (21); focusing means (30) set up for focusing the laser beam (21) on a preset area or spot (S); motor means, set up for determining a translation of a slab (T) to be cut and/or of the spot (S) along a cutting direction (X) such that, for a preset interval of time, the corresponding movement between the slab (T) and the spot (S) along the cutting direction (X) is nil.
摘要:
Bei einem Verfahren zur Messung der Tiefe der Dampfkapillare (88) während eines industriellen Bearbeitungsprozesses mit einem Hochenergiestrahl (19) wird ein optischer Messstrahl (70a) auf den Boden einer Dampfkapillare (88)gerichtet. Aus Reflexen des Messstrahls (70a) erzeugt ein optischer Kohärenztomograph (40) Interferenzspektren oder andere Roh-Messdaten. Eine Auswerteinrichtung (114) erzeugt entstörte Messdaten, indem Roh-Messdaten, die zu unterschiedlichen Zeitpunkten erzeugt wurden, im Wege einer mathematischen Operation gemeinsam verarbeitet werden. Bei dieser Operation kann es sich insbesondere um eine Subtraktion oder eine Division handeln. Dadurch lassen sich langsam verändernde Störeinflüsse eliminieren. Aus den entstörten Messdaten wird mit Hilfe eines Filters, z.B. eines Quantil-Filters, ein Endwert für den Abstand (a1) zum Boden der Dampfkapillare (88) berechnet. Daraus lässt sich in Kenntnis des Abstands zu einem Teil der Oberfläche (91) des Werkstücks (24), der nicht dem Hochenergiestrahl (19) ausgesetzt ist, die Tiefe der Dampfkapillare (88) bestimmen.
摘要:
The machine comprises: a working head (12) with a focussing device (18) arranged to focus a laser beam on the surface of the tube or profiled section (T) to be worked, a carriage (26) on which the working head (12) is mounted and a scanning system (20) arranged to scan at least a portion of the outline of the cross-section of the tube or profiled section (T). The carriage (26) is able to translate with respect to the tube or profiled section (T) both in a longitudinal direction (x) coinciding with the longitudinal axis of the tube or profiled section (T) and in a transverse direction (y). The scanning system (20) comprises at least one laser scanning module (20) comprising a laser emitter (22) arranged to emit a light blade (L) with which to illuminate a portion of the tube or profiled section (T) and a camera (24) arranged to acquire an image of the portion of tube or profiled section (T) illuminated by the light blade (L). The working head (12) and the at least one laser scanning module (20) are mounted on the carriage (26) so as to be drivingly connected for translation with said carriage (26) both in the longitudinal direction (x) and in the transverse direction (y).

摘要:
An additive manufacturing system includes an energy gun having a plurality of energy source devices each emitting an energy beam. A primary beam melts a selected region of a substrate into a melt pool and at least one secondary beam heat-conditions the substrate proximate the melt pool to reduce workpiece internal stress and/or enhance micro-structure composition of the workpiece.
摘要:
Die Erfindung betrifft einen Laserbearbeitungskopf zur Bearbeitung eines Werkstücks (5) mit einem Laserstrahl (2), mit einer Halterung (11), einer strahlformenden Optik (15', 15''), die an der Halterung (11) in Längsrichtung des Laserstrahls (2) verschiebbar gelagert ist. Um eine Verschmutzung der Optik (15', 15'') weitgehend zu vermeiden und um die Optik (15', 15'') in ihrer eingestellten Lage sicher zu halten, selbst wenn große Trägheitskräfte in Folge von großen Beschleunigungen auftreten, ist ein Bandantrieb zur Verschiebung der Optik (15', 15'') vorgesehen.
