These feed rates are varied in relation to each other so that a desired contour is generated. Any term defined in IL1566 shall have the same meaning when used in this entry as it has in that entry. A “direct numerical control system” (DNC) means a system connecting a set of numerically controlled machines to a common memory for part programme or machine programme storage with provision for on-demand distribution of data to the machnes. Axis nomenclature shall be in accordance with international standard ISO 841, “Numerical Control Machines—Axis and Motion Nomenclature”. “Positioning accuracy” is that accuracy which would be obtained in a temperature-controlled environment of 20°C ± 2°C with any mechanical compensation techniques exported with the machine or any electronic compensation meeting the requirements in exception (iv) to head (a) above. “Positioning accuracy” of machines exported without numerical control units is that attained with a control unit used during checkout of the machine and with feedback systems identical to those that will be used with the machine, or by accuracy and feed back system and control unit which will be connected to the machine. The value of the positioning accuracy does not include the width of backlash. The value is determined by the usual statistical methods (random tests); ie by approaching from only one direction a minimum of 5 measuremen points up to a maximum of 25 measurement points as random tests along one axis. National standards may be used for this measuring method; eg the German standard VDI “Statistical testing of the operational and positioning accuracy of machine-tools VDI-DGQ3442, March, 1977”.
