Aspects relate to methods and systems for manufacturing orientation selection, using machine learning. An exemplary method includes receiving, using a computing device, a computer model representative of a part for manufacture, inputting, using the computing device, the computer model to a machine learning model, determining, using the computing device, a plurality of candidate orientations as a function of the machine learning model and the computer model, and ranking, using the computing device, each candidate orientation of the plurality of candidate orientations as a function of the machine learning model and the computer model.

A method of machining an elongate workpiece extending along a longitudinal axis and shaped to be supported rotationally instably about the longitudinal axis includes sensing a rotation of the workpiece about the longitudinal axis, thereby yielding a sensing result; and machining the workpiece at the machining station at least partly in dependence of the sensing result.

An apparatus for processing a component includes a multi-axis positioning device, a processing tool, and a control device for controlling the multi-axis positioning device. The multi-axis positioning device is configured to move the processing tool relative to the component and to move each axis of the processing tool within a corresponding work envelope. The control device is configured to limit the movement of the multi-axis positioning device along or about at least one limited axis within the corresponding work envelope to a subregion or subspace. The multi-axis positioning device and/or the component is configured to move about and/or along an external axis to compensate for the limitation of the movement along or about the limited axis.

A method and an apparatus for detecting and correcting a spatial position of a workpiece held in a positioning device, wherein a machining head having at least one sensor and position sensor is fed into at least one measuring position. Contactless sensing of an actual position of a measuring point of the workpiece is carried out at the measuring position using the machining head and the sensed actual position is compared with an expected nominal position and deviation values between the actual position and the nominal position are ascertained. The ascertained deviation values are compared with an admissible tolerance value and the machining head is fed to a contour when the ascertained deviation is within the admissible tolerance value, or the machining head and the workpiece are oriented with respect to one another and to the contour such that a deviation of the actual position is within the admissible tolerance values following orientation.

The present invention performs continuous machining while keeping the relative attitude of a tool and a workpiece stable during a program route and thus prevents unevenness occurring in a machining surface of the workpiece. This numerical control device is for a machining tool that performs machining while changing the relative position and relative attitude of a tool and a workpiece in accordance with a program and is provided with: a relative attitude setting unit that sets the relative attitude of the tool and the workpiece during each block or cycle of the program; a dividing unit that provides one or more division points in each block/cycle to divide the block/cycle into two or more sections; and a shaft control unit that moves the tool and workpiece relative to each other such that the tool and the workpiece take the relative attitude set by the relative attitude setting unit in at least one section among the two or more sections.
