<p>An apparatus and method are provided for creating and revising programmes for numerically controlled machines. First, generalised data block signals are produced, the generalised data block signals representing alphanumeric words defining block types, workpiece material types, work surfaces, workpiece features and machining operations. Then, machine control instruction block signals are produced in response to the generalised data block signals, the machine control instruction block signals represent alphanumeric words defining machine member motion in the form and format required by a particular numerical control. The generalised data programme may be created by a machine operator using data obtained from the workpiece design data. Generalised data programme creation and revision is accomplished without regard for the data requirements and limitations of a particular machine and control combination by which the workpiece is to be processed.</p> |
