Publication number: 20200189029Abstract: A profile selector includes at least one beam-forming lens refracting a laser beam to be incident so as to convert a beam profile and emits a laser beam having a beam profile selected from a plurality of beam profiles. A collimating lens converts a laser beam of a divergent beam to be incident into collimated light. A focusing lens focuses the collimated light emitted from the collimating lens and irradiates the focused beam to a sheet metal of a processing target. A moving mechanism moves the collimating lens along an optical axis such that a deviation of a focal point is reduced caused when the beam profile of the focused beam emitted from the focusing lens is selected by the profile selector.Type: ApplicationFiled: May 23, 2018Publication date: June 18, 2020Applicant: AMADA HOLDINGS CO., LTD.Inventors: Hiroaki ISHIGURO, Ryouhei ITO, Tetsuya KOBAYASHI

Patent number: 10559103Abstract: The present subject matter relates to generation of a geometry corresponding to a cross-sectional profile of an object. In an example method, a sketch corresponding to the cross-sectional profile of the object is received by a computing device. The sketch is drawn by moving a pointer over a display unit of the computing device. Pixel points generated by the display unit are obtained by the computing device. The pixel points correspond to the sketch. Low-speed pixel points, from amongst the pixel points, are joined with straight lines. The low-speed pixel points are the pixel points at which a speed of drawing of the sketch is below a predefined speed threshold. The straight lines are processed by the computing device into the geometry of the object.Type: GrantFiled: June 8, 2016Date of Patent: February 11, 2020Assignee: AMADA HOLDINGS CO., LTD.Inventor: Jackson Tholath
