APPLICATION & USE OF CAD SYSTEMS

There are various advantages of using CAD, as mentioned before. In addition to creating accurate product designs, CAD systems are increasingly being used to automate and manage the manufacturing process. CAD/CAM/CAE are popular examples. The benefits of using CAD systems are highlighted below:

Creating precise product design – By successfully integrating the geometrical and mathematical functions, with the design generating function, CAD systems have the ability to produce very precise product designs. Further, they allow both interactive and automatic analysis of design variants and the expression of designs in a form suitable for manufacturing. CAD systems allow users to view a design from any angle with the push of a button and to zoom in or out for close-ups and long-distance views. Additionally, they keep track of design dependencies. Thus, if a value in the design changes, all other values that depend on it are automatically modified accordingly.

Solid 3D modeling – With the advent of 3D modeling and its advanced features, CAD systems can create photo-realistic product images. This gives manufacturers the ability to manipulate 3D models as if they were actual solid objects and a replica of an existing object or concept. These can be used for various purposes, from tweaking and perfecting the design to marketing the product. Additionally, with advanced 3D modeling functionality, CAD systems are also becoming popular with media companies for creating animations.

All-in-one manufacturing solution – Factory automation systems, such as CAD/CAM and CAD/CAM/CAE, are increasingly being used by manufacturers to streamline their production. CAD systems are also used in robotics. Such systems allow NC programming to create actual products, or even for graphic development for the animation industry.

Product management - Under CAD, techniques like Concurrent Engineering and Product Life-cycle Management (PLM) were developed. These techniques have allowed organizations to re engineer their entire design and production process.

APPLICATION AREAS

Automotive :

With frequent introduction of newer models and up gradation of existing models, automotive design cycle time has reduced considerably placing tremendous pressure on the system suppliers to quickly prototype and demonstrate their designs to OEMs.To remain competitive, automotive manufacturers need to innovate and reduce costs while keeping pace with stringent environment and safety standards making it imperative to push design & manufacture to low cost based countries such as India.

Automotive engineering design: Product design and development for Body-In-White (BIW), chassis, power train and drive line. Testing and analysis for thermal management, engine simulation, vehicle crash worthiness, fatigue and durability analysis, meshing, plastic design & mold design validation.

 Automotive electronics and embedded systems: Vehicle electronics, diagnostics, safety and security for areas like On Board Diagnostics (OBD), emission certification, air bag controls, seat belt controls and remote key-less entry systems; infotainment solutions for navigation, in-car entertainment and communication.

Automotive shop floor services: Digital manufacturing services for power train, BIW, paint shop, control systems solutions for press, body shop, paint shop, assembly, material handling and production control.

Automotive manufacturing solutions: Manufacturing Execution System ; adaptive manufacturing.

 Product Life-cycle Management (PLM).

  Engineering IT for automotive industry: Knowledge Based Engineering; vehicle tracking system.

Aerospace

Most aircraft are constructed by companies with the objective of producing them in quantity for customers. The design and planning process, including safety tests, can last up to three years for small turboprops, and up to 8-10 years for a large aircraft with the capacity of 300-400 passengers.

During this process, the objectives and design specifications of the aircraft are established. First the aircraft construction company uses drawings and equations, simulations, wind tunnel tests and experience to predict the behavior of the aircraft. Computers are used by companies to draw, plan and do initial simulations of the aircraft. Typically a medium sized aircraft design would involve 40,000 to 60,000 drawings. Small models and mockups of all or certain parts of the aircraft are then tested in wind tunnels to verify the aerodynamics of the aircraft. When the design has passed through these processes, the company constructs a limited number of these aircraft for testing on the ground.
