Vorrichtung zum Suchen von ähnlichen Bearbeitungsdaten und darauf basierende automatische Programmiervorrichtung

摘要

The invention relates to an apparatus that generates an NC program efficiently by using programming base data for a previously similar machines product. The apparatus comprises: (A) a historical data storing section (16) for prestoring programming base data which is base data for NC program generation and comprises (A.1) machining element data including configuration data concerning a workpiece and a product and process data concerning the kind of machining, and (A.2) tool-related data concerning a tool and machining conditions; (B) a machining element data generating section (13) for generating the machining element data for the product to be machined, based on three-dimensional shape data for the product to be machined and the workpiece; (C) and a searching section (15) for seaching in the historical data storing section (16) on the basis of the generated machining element data, and for extracting programming base data for a product similar to the product to be machined.
