In this paper, a novel method for incorporating automatic, patient-specific, structural analysis in computer-aided preoperative planning is described. Special emphasis has been placed on accurately capturing the mechanical behavior of the implant-to-bone interface where failure may occur. A finite element solver was developed and integrated into our computer-aided planning system for implant de...

An important process-planning task in sheet-metal manufacturing is the determination of bending sequences for individual components. Computer-aided generation of these sequences, as part of a computer-aided process-planning (CAPP) system, can relieve the workload of process-planning departments, this being especially important in small batch manufacturing environments. This paper discusses the ...

The Computer Aided Process Planning (CAPP) systems are recently developed in manufacturing engineering to provide links between Design (CAD) and Manufacturing (CAM) systems. CAPP by considering the different issues of computer applications production engineering. Optimization techniques can be applied increase efficiency part processes. energy consumption process analyzed optimized using order ...

Mass customization is a dominant new trend in modern manufacturing, whereby industries are required to produce umpteen variations of products at costs approaching those achievable in mass production. Among the methods to tackle this demand is development of flexible tooling which operates at high throughput rates. A suite of such tools called MPATS (a Modular, Parametric, Assembly Tool Set) is ...

Fixture design is crucial part of manufacturing process. Fixture design is a critical design activity process, in which automation plays an integral role in linking computer-aided design (CAD) and computer-aided manufacturing (CAD). This paper presents a literature review in computer aided fixture design (CAFD) in terms of automation and optimization techniques over the past decades. First, the...

Quality control (QC) plan is an important component of manufacturing planning for mass customization. QC planning is to determine the operational tolerances and the way to control process variation for assuring the production quality against design tolerances. It includes four phases, i.e., tolerance stack-up analysis, tolerance assignment, in-process inspection design, and the procedure of err...

A graphical representation schema Updated Petri Nets (UPN) has been developed to model rule based company policy specifications, in the context of computer integrated manufacturing systems. UPN facilitates the modeling of relationships between operations of various related application systems and the database updates and retrievals among all the CIM databases. Based on this representation, a hi...

Decision making and technical decision analysis demand computer-aided techniques and therefore more and more support by formal techniques. In recent years fuzzy decision analysis and related techniques gained importance as an efficient method for planning and optimization applications in fields like production planning, financial and economical modeling and forecasting or classification. It is ...
