摘要： A system and method for error compensation in positioning a complex-shaped gas turbine engine part during manufacturing thereof with a machine. Theoretical measurements for a plurality of control points on the part are first retrieved. Actual measurements for the control points are then acquired in a coordinate system of the machine. If an error between the actual and theoretical measurements is beyond a tolerance, a transformation matrix is computed. The transformation matrix represents a transformation to be applied to the coordinate system to adjust a pose thereof for compensating the error. The transformation matrix may be computed and applied to the coordinate system iteratively until the actual measurements are brought within tolerance. A machining program may then be generated for manufacturing the part accordingly.

摘要： Manufacturing systems and methods are disclosed. In one example, a computer based system comprises a non-transitory computer readable memory, a processor, and logic instructions stored in the non-transitory computer readable memory. When executed by the processor, the logic instructions configure the processor to perform operations, comprising receiving a first digital map of a first component and a second digital map of a second component, defining a first surface on the first component and a second surface on the second component, wherein at least a portion of the first surface is to adjoin at least a portion of the second surface in a manufactured assembly, updating a first part definition for the first component to include the first surface and, optionally, updating a second part definition for the second component to include the second surface.

摘要： A system for establishing data defining a path for machining tool such as a three-axes milling machine tool. The machining tool path is established within a three-dimensional rectangular coordinate system which corresponds to a machine coordinate system for numerical control. The tool path is established along a first coordinate axis. The tool path is shifted to an adjacent path along the first coordinate axis in a second axis direction. The shifting pitch of the path corresponds to the interval of said path along the first the coordinate axis. The tool is shifted in third axis direction during travel along the path defined in the first and second axis direction.

摘要： A three-dimensional (3-D) printer and a method for adjusting a working coordinate of a platform thereof are provided. The 3-D printer includes a platform, a printing head and a control unit. The platform includes a carrying surface and adjustment points located on the carrying surface. The printing head disposed above the platform for moving along a datum plane and a normal direction of the datum plane. The control unit controls the printing head to move from the datum plane toward the platform to contact each of the adjustment points for obtaining a coordinate offset of the carrying surface corresponding to the datum plane, and adjusts a model coordinate of a digital 3-D model information according to the coordinate offset. The control unit moves the printing head according to the adjusted model coordinate to print a 3-D object related to the digital 3-D model information on the carrying surface.
