Patent number: 7444850Abstract: The invention relates to a method for operating a shaping machine (1) having a tool (2), in particular a shaping machine having a shaping tool, in which the workpiece is handled by means of a handling device (3) during the manufacturing process. To improve the production process, the invention provides that before machining of workpieces on the shaping machine (1), the position and/or orientation of the tool (2) is/are determined by approaching at least one reference surface (5, 6, 7, 8, 9, 10) on the tool (2) with a handling device (3) equipped with at least one sensor (4, 4?), transmitting the determined positions of the reference surfaces (5, 6, 7, 8, 9, 10) to an evaluating means (11), and determining in the evaluating means (11) the position and orientation of the tool (2). The invention further relates to a shaping machine.Type: GrantFiled: May 28, 2004Date of Patent: November 4, 2008Assignee: Langenstein & Schemann GmbHInventors: Lothar Bauersachs, Harald Barnickel

Patent number: 7415856Abstract: Implementations of the present invention relate to a method and a corresponding device for shaping a workpiece, in which the lifting of the workpiece from the tool after a shaping process is automated. One implementation of the method relates to (a) placing the workpiece in a shaping position on a first tool of the shaping machine, (b) moving the tools of the shaping machine toward one another, (c) shaping the workpiece between the tools, (d) subsequently moving the tools away from one another, (e) identifying a triggering time when the relative motion of the tools has reached a reference position.,(f) determining a lifting time, which may be a function of the triggering time, and (g) initiating a lifting motion of the workpiece from the first tool by at least one handling device at lifting time.Type: GrantFiled: May 28, 2004Date of Patent: August 26, 2008Assignee: Langenstein & Schemann GmbHInventors: Lothar Bauersachs, Harald Barnickel
