NanoPositioning is a combination of piezoelectric ceramics, capacitance sensors and flexure hinges, and is the art of positioning in space with resolutions of one nanometre and less. Describes the technologies involved and how they are applied to the growing demand for precision mechanisms.
Describes an application using machine vision as a sensing device to allow robots to adapt according to their use. Describes the application in focus, lists the requirements of the cell and provides the solution. Provides details of the system used, emphasizing in particular its adaptability.
Details a new type of screwing mechanical hand which has been developed. There are three distinguishing features on the structures and functions of the mechanical hand: it can perform both screwing and unscrewing automatically; it has no special driver for its finger grasp and release but adopts...
Describes a new evaluation method for the orientation characteristics of parts, based on the idea that within Euclidean 3D space there should exist three, instead of two, symmetries. Demonstrates that evaluation of orientation characteristics by this method for any type of part shape is simple,...
Discusses manufacturing control systems using Cheltenham‐based assembly firm, Wynn Marine, as an example. Finds that here a new system of computing has halved the time taken to input orders.
Addresses the problem of printed circuit board inspection. Gives an example of an approach which aims to overcome the difficulties associated with it.
Looks at the advantages of dimensional management in improving quality and reducing cost through controlled variation and robost design as opposed to the more traditional tolerance assignment. Lists the limitations of tolerance assignment and details the six basic steps of the dimensional...
