System and method for performing operations of numerical control machines

A method for machining a workpiece by a numerical control (NC) machine, comprising:

• acquiring images of a scene represented by a set of three-dimensional (3D) points using a 3D sensor, wherein the images of the scene include a set of a plurality of NC machines and a corresponding set of workpieces;
• providing a 3D model of an NC machine for each of the set of NC machines;
• constructing a 3D model of the scene from the images of the scene including at least a part of each of the set of NC machines and at least a part of each of the corresponding set of workpieces;
• registering the constructed 3D model of the scene with the 3D model of the NC machine for each of the set of NC machines by matching the part of each of the set of NC machines included in the constructed 3D model of the scene with respect to the machine 3D model to produce a first transformation between a coordinate system of the constructed 3D model of the scene and a coordinate system of each of the set of NC machines in the 3D model of each of the NC machines;
• detecting each of the corresponding set of workpieces included in the constructed 3D model of the scene to produce a second transformation between the coordinate system of the constructed 3D model of the scene and a coordinate system of each of the corresponding set of workpieces;
• combining the first and the second transformations to register the coordinate system of each of the set of NC machines with the coordinate system of each of the corresponding set of workpieces;
• and
• machining each of the corresponding set of the registered workpieces with a tool of each of the set of NC machines according to the registration of the coordinate system of each of the set of NC machines with the coordinate system of each of the corresponding set of the registered workpieces,
• wherein at least some steps of the method are performed by at least one processor.
