CAD & CAE.There's new or enhanced simulation software Simulation software is based on the process of imitating a real phenomenon with a set of mathematical formulas. It is, essentially, a program that allows the user to observe an operation through simulation without actually running the program. for almost any process. In addition to few CAD/CAM CAD/CAM in full computer-aided design/computer-aided manufacturing. Integration of design and manufacturing into a system under direct control of digital computers. software introductions - mostly aimed at machining tasks - NPE NPE NullPointerException (Java) NPE Network Processing Engine NPE National Policy on Education NPE National Plastics Exposition NPE Natural Penis Enlargement NPE Nutrition Program for the Elderly will showcase numerous simulation tools for processors who would rather have experiment on a computer screen than in tool steel. MOLDING SIMULATION Look for brand-new versions of the two most popular injection molding injection molding n. A manufacturing process for forming objects, as of plastic or metal, by heating the molding material to a fluid state and injecting it into a mold. simulations, offered by C-Mold in Louisville, Ky., and Moldflow Pty., Lexington, Mass. Chief among the new features in C-Mold 97.7 is simplified Internet access. Icons within C-Mold can open an Internet browser or send e-mail. This change lets users visit on-line resources while still working within C-Mold. Those resources include C-Mold's site on the World Wide Web (www.cmold.com), which now offers software enhancements and free access to the company's growing materials database. E-mail capability enables users to share C-Mold results faster. Other enhancements include 174 additional new materials in the database, improved juncture-loss simulation to handle more combinations of runner-diameter sections, and expanded cooling simulation to cover bubblers and baffles with variable cross sections. Moldflow will bring out Release 9.3 of its Dynamic Series software. Among the new features is MF/Cool Gas, which lets users optimize cooling-circuits in gas-assist molding. Mold-flow will also demonstrate its new Intelligent Process Control system, which applies simulation results to shop-floor process optimization. Rapra Technology will show a new version of FillCalc, a PC-based mold-filling simulation package that now has improved links to a variety of CAD systems. In addition, new "quick-check" part-verification tools that quickly and simply indicate whether a part can be filled successfully will join ones already on the market from C-Mold, Dallas-based Plastics & Computer Inc., and The Madison Group, Madison, Wis. One new product of this type is Mold-flow's Part Advisor (see Technology Newsfocus). SIMULATING OTHER PROCESSES Besides injection molding, there will also be simulation news for other processes: * Compression Molding - New "Express" from M-Base Engineering + Software of Aachen, Germany, simulates compression molding of reinforced thermoplastic A polymer material that turns to liquid when heated and becomes solid when cooled. There are more than 40 types of thermoplastics, including acrylic, polypropylene, polycarbonate and polyethylene. sheet. It predicts flow, fiber orientation, shrinkage, and warpage. Similar capabilities for thermoset A polymer-based liquid or powder that becomes solid when heated, placed under pressure, treated with a chemical or via radiation. The curing process creates a chemical bond that, unlike a thermoplastic, prevents the material from being remelted. See thermoplastic. SMC SMC Saint Mary's College SMC Santa Monica College SMC Solaris Management Console SMC Smooth Muscle Cell SMC Small Magellanic Cloud (also see LMC) SMC Safety Management Certificate (maritime shipping) are offered by Cadpress Version 2.0 from The Madison Group. * Thermosets thermosets, materials that can not be softened on heating. In thermosetting polymers, the polymer chains are joined (or cross-linked) by intermolecular bonding. Thermosets are usually supplied as partially polymerized or as monomer-polymer mixtures. - Thermoset 3-D from The Madison Group analyzes curing and residual stresses in thick parts such as cast-marble sinks. * Blow molding, thermoforming - C-Mold 97.7 for blow molding and thermoforming processes has improved Internet and e-mail access, as noted above. * Extrusion - Scientific Process & Research Inc., Somerset, N.J., will bring out a Windows 95 extrusion simulation package called Extrud 97. * Shrinkage, warpage - Stress Engineering Services, Houston, will show new software for predicting effects of autoclave autoclave Vessel, usually of steel, able to withstand high temperatures and pressures. The chemical industry uses various types of autoclaves in manufacturing dyes and in other chemical reactions requiring high pressures. sterilization sterilization Any surgical procedure intended to end fertility permanently (see contraception). Such operations remove or interrupt the anatomical pathways through which the cells involved in fertilization travel (see reproductive system). on medical parts and assemblies. Drop-impact simulation will also be shown. What to Look for: * Simulation software for injection, compression, and blow molding, thermoforming, and extrusion. * A new gas-simulation module. * Seamless Internet access for popular mold-filling software. * Quick-check flow-simulation programs. |
