Research ArticleOpen accessIn the keywordsDesign and Manufacturing of a Custom Skull ImplantJuan Felipe Isaza Saldarriaga, Santiago Correa Vélez, M.D. Adolfo Cumplido Posada et al.Problem statement: Cranioplasty is defined as a neurosurgical procedure to cover an injured bone in the skull. This procedure is carried out in order to protect and restore intracranial structures and to restore the appearance and psychological stability of the patient. Advances in medical imaging, such as MRI and CT, have allowed the 3D reconstruction of anatomical structures for several … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 17 Mar 2011 · 9,565 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Learning Platform for Computer Numerical Control (CNC) LaboratoryCharinee Chaichana, Seetala Wongkalasin, Apichat SanrutsadakornInformation Technology has played a major role in education. Rajamangala University of Technology, Isan Sakonakhon Campus, is committed to promoting a 21st Century education. For example, the university provides an environment that supports this development by integrating the use of Computer Numerical Control (CNC) in teaching practices. The model of CNC machines used in teaching and learning is outdated though, … …Journal of Computer Science, Vol. 18, Issue 8 · 4 Aug 2022 · 6,951 accessesView PDF Cite

Research ArticleOpen accessIn the abstractModel Predictive Approach to Precision Contouring Control for Feed Drive SystemsM.A. El Khalick, N. UchyiamaProblem statement: High precision machining requires high capability of multi-axis feed drive systems to follow specified contour accurately. Although each feed drive axis is controlled independently in many industrial applications such as X-Y tables and Computer Numerical Control (CNC) machines, machining precision is evaluated by error components orthogonal to desired contour curve. Contouring controller design is required for precision machining, … …Journal of Computer Science, Vol. 6, Issue 8 · 31 Aug 2010 · 7,309 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordA Drives and Control Integrated Time-Domain Dynamic Analysis and Modeling Approach Applied To Ultra-Precision Machine ToolsTianjian Li, Shijin Chen, Haijun Zhang, Kai ChengProblem statement: Machines dynamic performance depends not only upon the mechanical structure and components but also the drives and control system. However, the design of the machines is still at the nascent stage by working on an individual machine basis, hence lacks generic scientific approach and design guideline. Approach: Using computer models integrated drives and control system to predict the … …Current Research in Nanotechnology, Vol. 2, Issue 1 · 29 Jul 2011 · 8,088 accessesView PDF Cite
