Embodiment Construction

[0088] figure 1 A method 100 according to an embodiment of the invention is schematically shown. The steps of method 100 are at figure 2 is shown in the flowchart. The method 100 is suitable for manufacturing a workpiece 101 into a product 102 by successively cutting blocks of material from the workpiece 101 . The workpiece 101 may in particular be a rough diamond (see e.g. Figure 8 ), and product 102 may in particular be a faceted diamond (see e.g. Figure 7 ) or another faceted gemstone. Product 102 may be planned prior to performing method 100 , where the planning may be based on the shape and volume of workpiece 101 . To manufacture product 102 , method 100 continuously cuts away blocks of material from workpiece 101 until the desired complex shape of product 102 is achieved. To perform cutting, the method 100 utilizes an apparatus 300 that provides a laser beam 103 coupled into a pressurized fluid jet 104 (see image 3 ).

Abstract

The invention relates to a method and an apparatus for manufacturing a workpiece (101), specifically a rough diamond, into a product (102), specifically a brilliant. The method is performed by an apparatus providing a laser beam (103) coupled into a pressurized fluid jet (104). The method comprises executing multiple cuts of the workpiece (101) with the laser beam (103) according to a predetermined cut-sequence to remove workpiece (101) material with each completed cut. The method further comprises executing multiple rotations of the workpiece (101) around the same axis (106) of revolution according to a predetermined rotation-sequence (107). Thereby, a rotation is executed after a completed cut, and for executing a cut the laser beam (103) is moved along a two- dimensional path (108).

Description

technical field [0001] The present invention relates to a method and apparatus for manufacturing workpieces, especially rough diamond or other superhard materials, into products, especially brilliant diamonds or other faceted gemstones. The method uses the device, and the device is configured to provide a laser beam coupled into a pressurized fluid jet. A laser beam is used to cut the workpiece multiple times to shape the product. The product can be manufactured fully automatically from workpieces. Background technique [0002] Forming workpieces made of superhard materials such as diamond (natural) and / or synthetic diamond into products of the desired complex shape is very challenging. Especially when high forming accuracy is required. For example, diamonds (rough stones) are often manufactured in complex shapes including "round", "faceted", "emerald", "pear" or "princess". These complex shapes have multiple facets that must be cut with a very high degree of accuracy. ...
