It is a computer-aided design CAD based computer application. It is a 3-D modeling based computer application. AutoCAD is used by civil engineers, architects, town planning companies, graphic designers etc. Sketchup is used by architects, interior designers, film-makers, 3D modelers etc. What is an example of CAD? Blender — an open-source CAD, animation, and image processing application with an active community of users.
What are 3 advantages of CAD? Higher Quality Designs. Reuse and Easily Change Designs. Easier to Read. Simplified Sharing. Documenting the Design. Skill of the Designer. Designing Physical Objects in a Virtual Workspace. An American multinational software corporation, Autodesk offers a wide range of software products for designers, engineers, and architects.
By summing the limes for the individual element, required to perform a new Job, the program calculates the standard lime for the job. These packages are discussed in. Cost estimating, The task of estimating the cost of a new product has been simplified in most industries by computerizing several of the key steps required to prepare the estimate. The computer is programmed to apply the appropriate labor and overhead rates to the sequence of planned operations for the components of new products.
Production and inventory planning. The computer has found widespread use in many of the functions in production and inventory planning. These functions include: maintenance of inventory records, automatic reordering of stock items when inventory is depicted. We discuss these activities in Chapter Computer-aided line balancing. Finding the best allocation of work elements among stations on an assembly line is a large and difficult problem if the line is of significant size.
Computer programs have been developed to assist in the solution of this problem Section Manufacturing Control. The second category of CAM application is concerned with developing computer systems to implement the manufacturing control function.
Manufacturing control is concerned with managing and controlling the physical operations in the factory. These management and control areas include:.
Process monitoring and control. Process monitoring and control is concerned with observing and regulating the production equipment and manufacturing processes in the plant. We have previously discussed process control in Chapter 4. The applications of computer process control arc pervasive today in automated production systems.
They include transfer lines. All of these topics have been covered III earlier chapters. Quality control: Qua1ity control includes a variety of approaches to ensure the highest possible quality levels III the manufactured product. Quality control systems were covered in the chapters of Pan IV. Shop floor control. Shop floor control refers to production management techniques for collecting data from factory operations and using the data to help control production and inventory in the factory.
We discuss shop floor control and computerized factory data collection systems in Chapter Inventory control. Inventory control is concerned with maintaining the most appropriate levels of inventory in the face of two opposing objectives: minimizing the investment and storage costs of holding inventory and maximizing service to customers.
Inventory control is discussed in Chapter Just-in-time production systems. The term just-in-time refers to a production system that is organized to deliver exactly the right number of each component to downstream workstations in the manufacturing sequence just at the lime when that component ts needed. The term applies not only to production operations but 10 supplier delivery operations as well. Just-in-time systems are discussed in Chapter Product design, engineering analysis, and documentation of the design e.
