  Title Graphics based path planning for multi-axis machine tools Type Journal Article
  Year 2010 Publication Computer-Aided Design and Applications Abbreviated Journal  
  Volume 7 Issue 6 Pages 835-845  
  Keywords Computer graphics equipment;Machine tools;Scanning;Three dimensional computer graphics;  
  Abstract This paper discusses a graphics-based approach to the tool path and trajectory planning problem found in machining and robotics applications. Ray casting is used to determine part and blank surfaces from voxel model representations. Tool paths are generated from the ray intersections with the voxels and uncut material is used to determine optimal re-orientation. The algorithm presented is a first step towards automatic path generation for 5-Axis machine tools. The groundwork is laid to demonstrate the power of graphics hardware on manufacturing problems. The resulting tool path is validated by experimental results carried out by multi-axis milling of a free-form surface with undercut regions. © 2010 CAD Solutions, LLC.

  Title Efficient fitting of subdivision surfaces by simplified Newton method Type Journal Article
  Year 2010 Publication Computer-Aided Design and Applications Abbreviated Journal  
  Volume 7 Issue 6 Pages 821-834  
  Keywords Approximation theory;Three dimensional computer graphics;  
  Abstract In this paper, we present an efficient iterative fitting method of a Loop subdivision surface along with an approximation method of mesh data. We propose a simplified Newton method which uses errors at one neighbor control points and obtains the control mesh in order (n) for input points. We show the effectiveness of the method by calculations of some examples. © 2010 CAD Solutions, LLC.

  Title Multi-agent feature based shape grammar implementation for concept generation of industrial product design Type Journal Article
  Year 2010 Publication Computer-Aided Design and Applications Abbreviated Journal  
  Volume 7 Issue 6 Pages 797-807  
  Keywords Conceptual design;Industry;Telecommunication equipment;  
  Abstract The paper reports an agent based framework for the conceptual design generation stage of the Industrial product design process. The conceptual design is characterized by the multiple design generation and evaluation of the product concepts. The framework simulates the design team paradigm. Agent based architecture offers the advantage of being flexible, extendable and distributed. Added multiplicity of the shapes is achieved through the parametric variation and morphing of the feature elements. The implementation is demonstrated using a running example of a mobile phone, as it is simple enough to demonstrate the concept as well as complex enough to incorporate the team based paradigm of the design environment. The research is an effort to develop a design system to support the automatic concept generation and evaluation for the mass customization of industrial products. © 2010 CAD Solutions, LLC.

  Title Computer-Aided stress analysis and optimization of rolling mill housing Type Journal Article
  Year 2010 Publication Computer-Aided Design and Applications Abbreviated Journal  
  Volume 7 Issue 6 Pages 787-795  
  Keywords Computer aided analysis;Computer aided engineering;Design;Fatigue of materials;Housing;Milling machines;Optimization;Stress analysis;Stress concentration;  
  Abstract This paper presents optimization of rolling mill housing design for rigidity to have better gage control of the material being rolled. The stress distribution of housing is analyzed using Computer-Aided Engineering (CAE) by calculating maximum static stress at critical areas. Comparing the stress distribution before and after the optimization, the stresses of housing after optimization has considerably been reduced under the given boundary conditions and is within the recommended value. To calculate the stresses in actual conditions, a prototype of optimized housing design is generated in 1:10 scale. The results of the CAE analysis are compared with the experimental results getting from the prototype of optimized design and a good correlation between the results has been observed. © 2010 CAD Solutions, LLC.

  Title Growth simulation of facial/head model from childhood to adulthood Type Journal Article
  Year 2010 Publication Computer-Aided Design and Applications Abbreviated Journal  
  Volume 7 Issue 5 Pages 777-786  
  Keywords Health care;  
  Abstract This paper presents a method to simulate the growth of the facial/head model of a person from childhood to adulthood. The method works by generating continuous data of standard landmarks using auto-regressive moving average based on anthropometry of the head/face. The standard landmarks are assigned to the particular head and face, and vertices of the growing head/facial model are calculated by projecting the vertices to the one dimensional subspace that contains measurements of the landmarks. The vertices of the predicted model are constrained to keep the features of the head/face distinct by grouping vertices into clusters and maintaining proportional change of each cluster in different age periods. This new technology has applications in security, ID search (for missing children), health care (such as, evaluation of dysmorphic children) and forensic sketch artistry. © 2010 CAD Solutions, LLC.
