摘要:
The disclosed method for machining flat workpieces (6), in particular metal sheets, or three-dimensional workpieces (6') on a machining unit (1), especially a machine tool or laser cutting machine, involves the following steps: a) having an image capturing device (12) for capturing two-dimensional images capture a live image (14) of a workpiece (6; 6') to be machined; b) displaying at least one upcoming workpiece machining process (10 1 , 10 2 , 10 3 ) in the live image (14) of the workpiece (6; 6') using a predetermined forward transformation (T; T') of the workpiece machining process (10 1 , 10 2 , 10 3 ) from the three-dimensional coordinate system (11) of the machining unit to the two-dimensional coordinate system (15) of the live image; c) manually adjusting the position of the upcoming workpiece machining process (10 1 , 10 2 , 10 3 ) in the live image (14) of the workpiece (6; 6'); and d) carrying out the workpiece machining process (10 1 , 10 2 , 10 3 ) on the workpiece (6; 6') using a predetermined inverse transformation (T -1 ; T '-1 ) of the positionally adjusted workpiece machining process (10 1 , 10 2 , 10 3 ) from the two-dimensional coordinate system (15) of the live image to the three-dimensional coordinate system (11) of the machining unit.

A method and appertaining system implement the use of manufacturing protocols for hearing aid design such that the ability to build an instrument can be displayed as a numeric parameter based on the partial numerical and metrological contributions of all the essential parameters of the given impression, and a buildability index can be displayed as a 3D virtual image of the proposed shell or preferred shell types. The method utilizes a predefined parameter table comprising parameters to utilize for a buildability determination. The buildability index is computed based on impression shape data, selected shell type, selected number of device options, data obtained from the parameter table, and data obtained from a receiver table, and the buildability index is output to a display of a user interface device or an external system.

The invention relates to an automated method for the non-destructive inspection of a mechanical part (14), comprising comparing images of the surface of the part with reference images stored in a database using a device (10) for acquiring digital images which comprises an image sensor (24), an illuminating light source (26), and means (18, 22) for the relative movement of the image sensor (24), the light source (26) and the mechanical part (14).
摘要:
A method for the preparation of sculpted objects comprises the steps: (a) scanning at least a portion of the object to be sculpted to prepare an image data set; (b) modifying the image data set; and (c) preparing a completed sculpture using the modified image data set. The method preferably comprises the steps of (a) assessing an object to be sculpted and identifying portions of the object with a level of detail greater than a predetermined threshold; (b) scanning the object with the exception of the portions identified in step (a) to have detail above the predetermined threshold to provide an image data set; (c) modifying the image data set to include data for the omitted portions, to provide a complete image data set for the object; and preparing a completed sculpture using the modified data set. In an alternative method, the sculpture is prepared by the steps of (a) scanning a portion of an object to provide an image data set; (b) preparing a partial sculpture of the scanned portion of the object using the image data set using a first technique; and (c) preparing a full sculpted object using a second technique. Method preferably employs rapid prototyping to convert the image data set into a three-dimensional replica or finished sculpture.
