Abstract: The present disclosure relates to systems and methods for searching a machining knowledge database that includes stored 3D models and associated stored part signatures. The stored part signatures each include a shape metric that corresponds to geometric attributes of the corresponding 3D model. Methods include receiving input from a user relating to an input part, determining an input part signature that includes a shape metric that corresponds to geometric attributes of the input part, searching the machining knowledge database for similar 3D models based at least in part on the input part signature, and providing the search result to the user. Methods may include associating the input in the machining knowledge database and/or utilizing the search result, for example visualizing a comparison of the input and the search result.

Abstract: The present disclosure relates to systems and methods for machining knowledge reuse by determining a machining strategy for a designated part to be formed, based at least in part on machining strategy information used to form one or more similar parts. Methods include receiving an input representation (such as a 3D model) of the designated part, searching a machining knowledge database for one or more similar parts that have a shape similar to the designated part, retrieving machining strategy information that was used to form the similar parts, and deriving a machining strategy for the designated part based at least in part on the machining strategy information used to form the similar parts.

Abstract: An electromechanical variable valve actuator for selectively opening and closing an intake or exhaust valve in an internal combustion engine having a valve closure member and a valve seat which employs Lorentz forces by using a current carrying conductive armature coil which is connected to the valve closure member and placed in a fixed air gap and movable in a direction perpendicular to a magnetic field generated by a magnetic field generator and directed across the air gap. The electromagnetic vector force, know as the Lorentz force, exerted on the armature coil results from the cross product of the current and the magnetic field.
