The Accuracy Improvement of Machine Tools

CIRP Annals, 1990
This study deals with endeavours toward improving accuracy of machine tools through compensation for thermal drift and load-induced deflection. The spatial displacement of the tool and workpiece, caused by the above said factors, is expressed in terms of temperatures of various parts of machine tool for thermal drift and in terns of forces and loading ...

A study on the prediction of machining accuracy

The International Journal of Advanced Manufacturing Technology, 2008
The machining accuracy prediction has been widely studied in many manufacturing processes to achieve efficient control for production process. In this paper, a dynamic analysis model is proposed to develop the prediction model of machining accuracy. The dynamic analysis model has the advantage of high predictable power of the GM(1,1) model while at the

Machine Accuracies in Automatic Cartography

Cartographic Journal, The, 1967
AbstractThe nature of random errors, machine errors and execution accuracy are explained in relation to the accuracy requirements of automatic plotting and drawing. The importance of discontinuity in linework is stressed, emphasising the distinction between planimetric accuracy and 'aesthetic' accuracy.
