Abstract: A first nest structure and a second nest structure are brought into alignment. When the alignment of the first nest structure and second nest structure is obtained, the operation of at least one vacuum pump is controlled such that a bearing element is released from the first nest structure and secured in the second nest structure. Movement of the bearing element from the first nest structure to the second nest structure occurs without slippage resulting in preservation of a common frame of reference used when the bearing element is in the first nest structure and the second nest structure.

Abstract: A method for machining a workpiece using a programmable, numerically controlled machining system by calculating or retrieving a compensated toolpath based on comparing contact position from monitoring a vibration signal from a vibration sensor during probing of workpiece with rotating tool during relative motion therebetween. Contact position is compared to position from predetermined toolpath and wherein the predetermined toolpath extends between initial machining point and end machining point. Machining the workpiece is done along compensated toolpath. The method may be done for repeated passes of machining. The compensated toolpath may include an angle offset to a machining path coordinate system of the predetermined toolpath. Workpiece may be mounted in a multi-axis manipulator of machining system for the probing and machining Multi-axis manipulator may be computer controlled and may be part of a robot.
