Computer aided design of the manufacturing technology for anchors is presented in the paper. Evaluation of applicability of various materials for anchors, as well as analysis of the influence of process parameters on the in use properties of product, were the objectives of the research. In the material part, bainitic steels were considered as an alternative for the commonly used C-Mn steels. Possibility of elimination of the heat treatment was evaluated. Rheological models for the investigated steels were developed and implemented into the finite element code for simulations of drawing and multi stage forging. Criteria for the selection of the best manufacturing chain composed dimensional accuracy, tool life and product properties. Industrial trials were performed for the selected cycle and the efficiency of this cycle was evaluated. Finally, simulations of the in use behaviour of the anchor-concrete joint were performed. On the basis of the simulations the optimization task using strength of the joint as the objective function was formulated

Abstract The paper describes a belt design package which works from within a commercial Computer Aided Design and Drafting package (AutoCAD) environment and utilizes FORTRAN programs for design and selection of lowest weight components for the drive system. The components used in the process are available as stock items in U.S.A. The relevant information on these products is stored in commercial database management systems such as EXCEL and LOTUS 1-2-3. Output from the package consists of scaled drawing and tabular specifications.

The purpose of this research is to fabricate bio-model that based on Rapid Prototyping technology which is by using Fused Deposition Modeling (FDM) and designing an implant by using a Computer Aided Design technology. A case study from Hospital Kuala Lumpur which is the maxillofacial will be fabricated by using FDM technique. The completed 3D prototype or biomodel will be analyzed to makes the result more truthful in terms of the dimensional accuracy, operational error and cost analysis. Computer aided design technology is used to design the customized implant in order to replace the fractured maxilla part.

Manufacturing Chain

Computer aided design of the manufacturing technology for the fasteners is presented the paper. The particular objectives of the work were twofold. The first objective is evaluation of applicability of various materials for fasteners. Analysis of different technological variants is the second objective of the research. In the material part, bainitic steels are considered as an alternative for the commonly used carbon-manganese steels. This is a continuation of [1,2]. Possibility of elimination of the heat treatment was evaluated. Main features of the new generation of bainitic steels are discussed briefly in the paper. Rheological models for all steels investigated in the project were developed. The models were implemented into the finite element code for simulations of drawing and multi stage forging. Simulations of various variants of manufacturing chain were performed and the best alternative was selected. Criteria for the selection composed dimensional accuracy and tool life. Industrial trials were performed for the selected cycle and the efficiency of this cycle was evaluated. Finally, the optimization task was formulated. However, solution of the optimization problem is costly at this stage and improvement of the efficiency of the formulation will be the objective of further research. References 1.

Significant Factors

This paper examines students’ design exploration strategies in a sustainability-focused structural optimization task. The task was set up as a two-criteria optimization problem with the goal of simultaneously minimizing the weight and an environmental indicator for a pedal bracket design. Forty-two students in an undergraduate computer-aided design class solved this task as a week-long, take-home assignment. Our analysis shows the number of design iterations and the number of failed iterations were significant factors in determining overall performance on the task. We also found that the final shape, the number of material changes, and experiencing conflict in the objective functions between iterations, did not significantly affect task performance. Based on these findings, we discuss implications for computer-aided optimization tools in sustainable product design.
