    CADEXCAP: Integration of 2D CAD models of turned components with CAPP (1993)
    Springer
    The international journal of advanced manufacturing technology 8 (1993), S. 145-159 
    Details
    ISSN: 1433-3015
    Keywords: Design standard ; CAD/CAM ; IGES ; Data transfer

    Notes: Abstract EXCAP is a knowledge-based process-planning system for turned components. This paper describes a software package called CADEXCAP, which has been developed to integrate EXCAP and CAD systems via IGES. CADEXCAP deciphers a full 2 D model of a turned component developed on a CAD system and then, via IGES, fully automatically generates a product model in the EXCAP model format. It is clever enough to extract not only the geometrical information but also the other required information, such as geometrical and dimensional tolerances, surface finish and manufacturing instructions.

    Guidelines for building 2D CAD models of turned components in CAD-CAPP integration (1993)
    Springer
    The international journal of advanced manufacturing technology 8 (1993), S. 285-296

    Notes: Abstract EXCAP is a knowledge-based process-planning system for rotational components. CADEXCAP is software which has been developed to integrate EXCAP with CAD systems via IGES (Initial Graphics Exchange Specification). CADEXCAP deciphers a full 2D model of a turned component developed on a CAD system and then via IGES it fully automatically generates a product model in a format suitable for EXCAP. This paper describes the guidelines which have to be followed at the CAD modelling stage of the components which are to be used by CADEXCAP. Following these guidelines will guarantee the automatic extraction of complete product models. This not only includes the geometry but also includes nongeometric information such as toleranced dimensions, geometrical tolerances, manufacturing instructions and surface finish.

    An IGES pre-processor to integrate CAD and CAPP for turned components (1994)
    Springer
    The international journal of advanced manufacturing technology 9 (1994), S. 291-304 
    Details
    ISSN: 1433-3015
    Keywords: CAD/CAM

    Notes: Abstract EXCAP, is a knowledge-based process-planning system for rotational components. CADEXCAP is software which has been developed to integrate EXCAP with CAD systems via IGES (Initial Graphics Exchange Specification). CADEXCAP deciphers a full 2D model of a turned component developed on a CAD system and then via IGES it fully automatically generates a product model in a format suitable for EXCAP. CADEXCAP has a modular structure of three modules: “readiges”, “preprocess” and “postprocess”. The “preprocess” module, which is the concern of this paper, was written in FORTRAN77 to pre-process the IGES entities. The pre-processing process includes two main tasks. The first task is to extract only the necessary information from the IGES entities. The second task is to locate the entities in one coherent coordinate system, which is the model space coordinate system, using transformation matrices.
