    Concurrent intelligent rapid prototyping environment (1995)
    Springer
    Journal of intelligent manufacturing 6 (1995), S. 291-310 
    Details
    ISSN: 1572-8145
    Keywords: Concurrent engineering ; distributed blackboard ; expert systems ; knowledge-based systems ; rapid prototyping ; stereolithography
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Rapid prototyping technology enables rapid production of complex objects directly from a computer-aided design model without involving any tooling or conventional part programming. This has created a new set of problems associated with part design, process planning, support design and value engineering analysis of rapid prototyping parts. In this paper, a methodology for resolving these problems is described, which uses concurrent engineering, distributed blackboard, value engineering, knowledge-based and feature-based technologies. The functionality, design methodology and knowledge representation techniques of a concurrent intelligent rapid prototyping system for stereolithography form the main focus of this paper.

    A CAD/CAM system for the machining of precision cams using a half angle search algorithm (1998)
    Springer
    The international journal of advanced manufacturing technology 14 (1998), S. 180-184 
    Details
    ISSN: 1433-3015
    Keywords: CAD/CAM ; Cams ; CNC machining ; Interpolation method ; NC program
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract This paper describes a computer-aided design and manufacturing system for design and production of complex cam profiles within the specified tolerance using a half angle search algorithm developed for optimisation of CNC part programming of cam profiles. The algorithm provides a systematic searching method to determine the minimum number of NC points required for machining the specified profiles of plate cams within a user-specified tolerance. Based on this algorithm, the CAD/CAM system generates an accurate and economical CNC part program for cams. This is verified by experimental results, analysis from CAD system and comparison with results from other methods.

    A CAD/CAM System for High Performance Precision Drum Cams (1999)
    Springer
    The international journal of advanced manufacturing technology 15 (1999), S. 32-37 
    Details
    ISSN: 1433-3015
    Keywords: Key words.B-spline; Cam profiles; CNC machining; Cylindrical cams; Drum cams
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: This paper describes a computer-aided design and manufacturing system for the design and production of complex profiles for high-performance drum cams within the specified tolerance. The system graphically generates the cam profile on the cylindrical drum after performing an analysis of the kinematic performance for the prescribed follower motion, using a B-spline representation of follower curves. Eight different types of follower motion for a translating follower are considered. The kinematic performance is based on the criteria of achieving the lowest levels of velocity and acceleration for each curve. The system is also able to simulate the motion of the designed cam graphically. The system also recommends the best cam profile on the basis of comparing the kinematic performance of all the B-spline representations of all the follower motions.
