Abstract :
The factors affecting the selection of numerical input automatic positioning systems are considered. A review of current technique is given to indicate the order of system cost and complexity. Various economic and operational features, such as cost, speed, accuracy, life and flexibility are emphasized and input, measurement and control schemes are classified according to basic principles. The need for unity of conception in new machine design is stressed and the adaption or conversion of existing machines is considered. A novel requirement for a co-ordinate positioning machine allowed an integrated approach to the electronic and mechanical design of the ¿machine.¿ The resulting design is discussed in detail as an illustration.
