“…The first type of methods is the kinematic (or element) approach as seen in the work done by Love and Scarr, 13 DufEe and Malmberg. 2 The second method is the workspace approach, such as the works done by Leete 10 Jan, Chu and Liu.…”

This chapter presents a neural network based methodology for tracking time-varying machine tool volumetric errors. This methodology serves as a practical approach to achieve real-time machining quality control on CNC machine tools. To solve the inherent 3D time-varying problem, analytical as well as neural network approaches are employed in parallel to coup with nonlinearity. A multiple-sensor system is incor porated with the model for real-time CNC machine tool system monitoring and data acquisition. The data acquired by the sensor array will be processed by a trained neural network and the corresponding machining quality (workpiece dimensional ac curacy) will be jointly predicted by the analytical and neural net models. The results demonstrate that neural network based methodology is capable of predicting the er rors of any entire workpiece, or, if needed, the same information can serve as fast and excellent reference for on-line error compensation. 269 Neural Networks in Design and Manufacturing Downloaded from www.worldscientific.com by UNIVERSITY OF BIRMINGHAM LIBRARY -INFORMATION SERVICES on 03/20/15.

“…The development of modeling methods has been experienced many years and it turns out to be various kinds such as matrix translation method, error matrix method, rigid body kinematic, D-H method, model methods based on the multi-body system kinematics theory and so on. In 1973 Love and Scarr obtained the combined effects of the elemental errors in the machine tool and then developed the volumetric errors of a multi-axis machine by using the trigonometric technique [25]. In 1977 a matrix translation method was reported and a calibration technique using three-dimensional metrology on a coordinate measuring machine (CMM) was presented by Hocken et al [13].…”

“…To overcome these difficulties, corrective software can be used to compensate for the hardware imperfections. Since the 1970s, software-based error compensation schemes have blossomed (Love & Scarr, 1973;Bush, Kunzmann, & Waldele, 1984;Tan, Lee, Lim, Dou, & Seet, 1999a). Common to all these works and more is a model of the machine errors (see Hayati, 1983;Veitschnegger & Wu, 1986;Zhang, Veale, Charlton, Hocken, & Borchardt, 1985;Duffie & Maimberg, 1987;Weekers & Schellekens, 1995), which is either implicitly or explicitly used in the compensator.…”
