 Hello and welcome to the video lecture on selection of CAD-CAM software. Learning outcomes at the end of this session, students will be able to apply CAD fundamentals as well as advanced manufacturing technology to industry problems. The following topics will be discussed in this particular video lecture. Recap of fourth session which was about automation and CAD-CAM software. Then we will be discussing about how to select the CAD-CAM on what are the criteria or what are the rules to be followed while selecting CAD-CAM software. How is the automation achieved in different types of production? Continuous flow production, manufacturing, producing or processing materials without interruption. Example chemical plant oil reference, automation achievement, sensors technology to measure important process variables. Use of sophisticated control and optimized strategies. Fully computer automated lines, mass production, production in large amounts of a particular one product. Example engine blocks, automation achievement, automated transfer machines, dial indexing machines, fully automated assembly lines, industrial robots for spot welding, parts loading, spray painting, etc. Automated material handling system, batch production, production of medium lot sizes of some product and then shifting to next product. Process is repeated frequently. Example book, clothing, automation achievement. Use of numerical control, direct numerical control and computer numerical control machines. Adaptive control machining, robots for spot welding, part handling, etc. Computer integrated manufacturing systems. Job shop production, production of low quantities specialized product. The products are often customized and technologically complex. Example satellite, automation achievement. Use of numerical control, computer numerical control and direct numerical control machine. Use of robots for spot welding, spray painting, etc. Adaptive control manufacturing systems. Now we will be discussing about what are the rules while selecting a particular CADCAM CA software. So this is the following rules, capable, efficient 3D design, compatibility with customers and suppliers, drafting tools that meet your standards, reliability and stability, pleasant business relationships, built-in applications that help your business. Now I will be discussing in detail about this, capable, efficient 3D design. So these are the different designs I have obtained. The capable, efficient 3D design. The centerpiece of a 3D CAD is a 3D master model that's used for all aspects of manufacturing, product design and verification, drafting, tool design, numerical control, tool programming and inspection. The 3D model must accurately represent every part in your company's products and the relationships among them. To maximize efficiency, designers should be able to design in 3D with as few steps as possible without compromising product quality. When evaluating CAD software, find out how efficiently each package creates the types of products your company makes. For example, if your company makes sheet metal parts, pay attention to the special tools for creating them and automatically generating flat patterns. If your firm designs stylish products, look at the tools for creating free firm surfaces and blends between them. Designers of machinery should see how easy it is to assemble large number of parts and insert purchased parts such as fasteners from a library. Compatibility with customers and suppliers. In today's world, few manufacturers are vertically integrated. Most rely on a community of suppliers for parts, tools, subsystems, production equipment and design services that frequently span the globe. Whether your company is a supplier or a customer, it can benefit from exchanging 3D CAD files with customers and suppliers. When possible, choose a CAD system that's popular in your industry and supplier community. This choice will eliminate the need to translate files from one system to another. Translation takes time and sometimes introduces errors. Also look at each system's ability to import files from other systems. Make sure your CAD supplier supports international standards such as STEP, IGS, VDA and IDF. Evaluate the tools for repairing damage to imported ships. How easy they are to use and how well they work. Drafting tools that meet your standards. Even though you will be designing in 3D, your suppliers and factory workers will need drawings. A clear drawing shows information that isn't obvious in a 3D model. Critical dimensions and tolerances, material and surface finish specification and notes about processing such as curing or heat treatment. Be sure any 3D CAD system you buy can make drawings to your current standards for dimensions, tolerances, lettering and parts list. And be sure your drawings can be exported in popular formats such as PDF, DXF and DWG. Now pause this video for a few seconds and try to write answer to the following question. What is the full form of DXF? Now probably you have wrote answer to the following question. Reliability and stability. 3D design systems are more complex than 2D drawing systems. With all that code it's harder to get the bugs out. Unfortunately there are no standard measures of reliability for CAD as there are many types of systems and machinery. Browse customer forums for frequent reports about instability or software bugs. Ask companies that own 3D CAD in your city or industry how often they crash or lock up. If your company makes large assemblies be sure any CAD system you buy is capable of handling them efficiently. Some systems slow to a crawl when handling complex designs with high part counts. Pay particular attention to assembly performance if your products contain complex free form shapes, helical sweeps or arrays of holes or other features. Pleasant business relationships. Believe it or not some of the greatest sources of friction between buyers of CAD software and their customers are the non-technical business aspects for the relationship. Just as some airlines annoy customers with extra fees for check baggage, flight changes, drinks and blankets. Some CAD suppliers levy hidden charges for software and services that most customers need. To avoid aggravation and lower your cost look for suppliers who offer straightforward software packages that have everything you need. Look at the terms for floating licenses that enable designers who don't need CAD full-time to share licenses and be sure your best designers can use the software both at work and at home without hustles. Built-in applications that help your business. 3D CAD can be even more productive with special purpose software for design automation and analysis. If you need to simulate physical behavior such as kinematics, dynamics, stress, deflection, vibration, temperatures or fluid flow, look for a system that has integrated analytical tools or efficient interfaces to your preferred analysis software. Organizations with more than just a few designers need product data management software integrated with their CAD tools. Files from 2D CAD systems can be organized into file directories but because relationships among files in 3D CAD systems are so complex an automated system to store and organize them is necessary. Without PDM, designers can unknowingly overwrite each other's work and waste hundreds of hours each year. These are the following references. Thank you.
