Generation of needle motion profile in an individual section glassware forming system

摘要

The system (10) includes a number of operating mechanisms (12,14) and controller for controlling the operation of the mechanism. A memory stores number of motion profiles of one mechanism. Each profile comprises a set of position data versus time data. An indicator displays selectively one of the profiles as a graph of position versus time. An identification unit identifies on display of control points at spaced positions along the graph. An operator is allowed to select one of the control points, and to change at least one of position data and time data associated with the control point so selected. A computing unit automatically recomputes the position data versus time data for specific profile as a function of data changes at one control point. The recomputed position data versus time data is displayed as a recomputed graph of position versus time.
