Assignee:

Amada Company, Limited - Kanagawa-Ken

International Classification:

G06F 900

US Classification:

709328, 700182, 709315, 709313

Abstract:

An apparatus and method are disclosed for transferring part data, such as sheet metal part data, between computer-based application or CAD environments and for editing such part data. The application environments may include a 2-D CAD program environment and an object oriented bend model program environment. An interface is provided through which a 2-D CAD system may access data from the object oriented bend model system and by which data may be transferred between the systems to permit editing and updating of the part model within and from both applications. The interface may be implemented through a library or set of application program interface (API) functions and a message-based protocol (such as dynamic data exchange (DDE)) to facilitate the exchange of sheet metal part data. Various editing capabilities or tools may also be provided to enable, for example, the attachment of faces of the part or the shifting of one face relative to another face of the part.

International Classification:

G06T 1700

US Classification:

345420

Abstract:

A method, a system, and a computer program for graphically editing a computer generated sheet metal part model initially display the sheet metal part model on a computer display screen. The method, system, and computer program then select an entity of the sheet metal part model to edit, and select an editing operation to be performed on the selected entity. The method, system, and computer program also include performing the selected editing operation on the selected entity, and modifying the sheet metal part model in accordance with the performed editing operation. Finally, the method, system, and computer program display the modified sheet metal part model on the computer display screen so that a user views modifications of the sheet metal part model in real time.

International Classification:

G06T 1500

US Classification:

345419

Abstract:

A method of editing an assembly with CAD includes selecting, through navigation, a first element of a first part among parts displayed on a CAD screen, the parts being made of sheet metal and being assembled into the assembly, the navigation automatically selecting an element of a part under a cursor as the cursor is moved on the CAD screen, dragging the first part including the first element with the cursor in one of horizontal and perpendicular directions relative to the first element, selecting, through navigation, a second element of a second part among the parts displayed on the CAD screen, and attaching the first element of the first part to the second element of the second part.

US Classification:

703 1, 700182, 707502

Abstract:

A dimensioning system is provided for a computer generated model of a sheet metal part including a plurality of entities. The dimensioning system comprises a model display, an indicator, a selector, a dimension defining system, and a dimension display. The model display displays a representation of the model on a display screen. The indicator indicates to a user candidate entities of the model, in response to user events, that may be selected. The selector selects two entities of the model, based on an indicated candidate entity. The dimension defining system defines each dimension associated with the selected entities of the model. The dimension display displays dimension information on the display screen based on the defined dimension. A repositioning system is also provided for a computer generated model of a sheet metal part represented on a display screen. The sheet metal part has associated dimensions displayed along with the sheet metal part on the display screen.

Abstract:

A method for improving search quality by quantitative analysis of enterprise web access traffic is disclosed. This invention relates to the field of data processing systems and more particularly to the field of knowledge management in corporate or enterprise. Performing search on heterogeneous data in an enterprise is complex and challenging. Present day technologies deploy costly and time consuming methods involving manual operation of data integration, pre-processing, mining and interpretation tools. Further, these methods are inefficient in retrieving relevant data. The proposed method discloses a method for exhaustive monitoring and analysis of intranet traffic to identify and retrieve relevant data in enterprise search. Resource relevance is revealed by traffic analyzer based on empirical, content-independent metric. Further, analysis of intranet traffic provides effective, timely and personalized information resource to user for selective information discovery, cross-linking of disjoint data repositories, one-click navigation to popular applications, index trimming and the like.

US Classification:

700182

Abstract:

An apparatus is provided for resolving a collision between a first face and a second face of a sheet metal part represented by a 3-D model. The faces collide with one another when a 2-D model of a flat sheet metal part, designed on a CAD system, is folded into the 3-D model displayed on the CAD system. The apparatus comprises a detecting means, an analyzing means and an eliminating means. The detecting means is for detecting each collision between the faces which become adjacent in association with folding the 2-D model into the 3-D model. The eliminating means is for eliminating the collision by designing a 2-D model of a modified flat sheet metal part which can be folded without causing the collision.
