Product data management (PDM) has proven its value as a critical tool in handling the enormous amounts of technical information companies generate. Now the PDM industry is applying this experience to more affordable systems targeted at smaller organizations. Several suppliers have entered the market with economical approaches aimed specifically at midsized companies. Many companies use PDM to eliminate inefficiencies in the engineering change process. Diebold, Inc. reduced engineering change cycle time by 30 percent through process automation with PDM. IBM is using PDM technology in product development for sharing data among groups, designing tools tightly coupled with release and change processes, interfacing with procurement and other services, and establishing real-time communication of data across the enterprise. Engineers increasingly are using PDM viewing features to track subsystems. Virtual-mockup capabilities enable engineers to import all the parts files for a product designed in Solid Edge, regardless of computer-aided design (CAD) vendor or file format.

The emergence of computer-aided design (CAD) has propelled the evolution of the sheet metal engineering field. Sheet metal design software tools include parameters associated to the part’s forming process during the pattern drawing calculation. Current methods avoid the calculation of a first pattern drawing of the flattened part’s neutral surface, independent of the forming process, leading to several methodological limitations. The study evaluates the reliability of the Computer Extended Descriptive Geometry (CeDG) approach to surpass those limitations. Three study cases that cover a significative range of sheet metal systems are defined and the associated solid models and patterns’ drawings are computed through Geogebra-based CeDG and two selected CAD tools (Solid Edge 2020, LogiTRACE v14), with the aim of comparing their reliability and accuracy. Our results pointed to several methodological lacks in LogiTRACE and Solid Edge that prevented to solve properly several study cases. In opposition, the novel CeDG approach for the computer parametric modeling of 3D geometric systems overcame those limitations so that all models could be built and flattened with accuracy and without methodological limitations. As additional conclusion, the success of CeDG suggests the necessity to recover the relevance of descriptive geometry as a key core in graphic engineering.

The European Spallation Source (ESS), currently under construction in Lund, Sweden, will be the world’s most powerful source of neutrons. The goal is to deliver neutrons to users in 2019 and reach full power sometime in the middle of the following decade. One of the key issues for ESS is to develop a strategy, along with the proper innovative tools, to efficiently communicate and smoothly collaborate between divisions and groups inside ESS and with its outside collaborators, so-called In-Kind Contributors (IKC). Technical requirements related to the scope to be delivered are among the most important technical information to be exchanged. This information exchange is facilitated by using a commercial requirements management database that is accessible through the web. The physics multidisciplinary needs are linked with the engineering integration through LinacLego, which is a tool that provides all updated lattice data for the accelerator. The lattice information is then gathered and utilized to control the physical positioning of the mechanical engineering components for the accelerator. The precision for this operation is provided by a dedicated mechanical design skeleton in a Computer Aided Design (CAD) environment. Finally, the realization of all these steps is supervised in detail and continuously evaluated. In this way the required ESS machine design can be delivered, both in terms of the engineering and the physics aspects.

Good Move

Walter Lorenz Surgical Inc., Jacksonville, FL, specializes in the medical devices known as rigid fixation implants. Lorenz Surgical was purchased by Biomet Inc. of Warsaw, Indiana in the year 1992, which resulted in Lorenzo owning two computer-aided design (CAD) systems. In 1996, with the completion of Lorenz Surgical's new manufacturing facility in Jacksonville, all Lorenz operations were transferred back to Florida, including all the manufacturing equipment and its three seats of Unigraphics, which by then were running on Windows NT workstations. The company's management feels it could have stayed with Unigraphics and accomplished its goals, but that adding Solid Edge was a good move. It gave Lorenz flexibility in hiring, allowed it to buy more CAD seats than it could have if it had stayed with Unigraphics alone, and provided a very productive tool. Lorenz's surgical instruments are currently designed exclusively in Solid Edge. Instruments can be modeled in either CAD system, but the job goes faster in Solid Edge. The creators of Solid Edge put a lot of effort into usability, and this shows in how few mouse clicks are needed for common operations. Products that have many standard features, such as a screwdriver consisting of m any cylinders, are very quickly modeled in Solid Edge.

Different Levels

Design engineers create models of design artifacts with commercial Computer Aided Design (CAD) solid modeling systems and manage the data files through Product Data Management (PDM) systems. These systems stop short of providing support for querying and retrieving data from “within” the CAD data files. A true CAD query language that allows designers the flexibility to describe queries against single and multiple CAD files would be of great benefit for design engineers. This query language ought to be both datacentric and user-centric in nature. The design exemplar, a datastructure that provides a standard representation of design knowledge based upon a general constraint validation and satisfaction algorithm, is shown here to be a concept upon which a CAD query language may be developed. The first required extension of the design exemplar is the inclusion of logical connectives. Some insights into the different levels at which the extensions may be implemented are discussed. Also, some applications retrieving geometric data using this query language are demonstrated. The query language, as it evolves, is expected to support geometric retrieval across domains and offer an all-purpose approach to geometric retrieval.

In the agricultural sector, the loss of stability related to the use of self-propelled agricultural machinery (SPAM) has caused and continues to cause accidents, often with fatal outcomes. The probability of occurrence of this risk can be reduced by acting on various aspects, but above all the presence of a protective structure is necessary. Depending on the machine, the protective structure can be a roll-over protective structure (ROPS), or a tip-over protective structure (TOPS). Hence, to reduce this gap, a reverse engineering approach and virtual engineering methods were applied starting from the analysis of harmonized standards actually in force, with the goal of providing both a reference procedure to be used in the risk assessment analysis of SPAM’s protective structures and technical information to manufacture and install protective structure on old agricultural machinery. Two representative case studies were used to validate the procedure by means of finite element method (FEM) analyses and computer aided design (CAD) prototyping. Results show that the proposed approach can represent a useful indication for the safety update of this type of machinery.

Solid Edge

This article reviews computer-aided engineering software that is used to boost productivity ranges from computer-aided design (CAD) systems to product data management and visualization systems. MacDon Industries used a Solid Edge product to merge CAD and product data management (PDM) systems to give engineers easy access to already created designs. MacDon tracks its tens of thousands of part designs by use of Solid Edge so engineers do not have to spend considerable time searching for the designs. Bayside Automation of Canonsburg, Pennsylvania, which makes automated assembly systems on which fuse boxes, valves, and the like are made, has discovered another area where technology—in this case, simulation software—can cut costs and increase productivity. CAD and PDM software from Alibre of Richardson, Texas, help the supplier and manufacturer pass translated design information back and forth quickly.
