CAB computer application in industry and engineering

Industries and engineering use a lot of computer applications in there daily activities. it is basically there technological up gradation. the various uses of computers are computer based design; computer integrated manufacturing; computer aided manufacturings and material requirement planning .

CAD or computer aided design is  the use of computer  technology for the process of design and design-documentation  it provide the user with input-tools for the purpose of streamlining design processes; drafting, documentation, and manufacturing processes.

CIM or computer integrated manufacturing is the manufacturing method of using computers to control the entire production process.This integration allows individual processes to exchange information with each other and initiate actions. Through the integration of computers, manufacturing can be faster and less error-prone, although the main advantage is the ability to create automated manufacturing processes. CIM relies on closed-loop control processes, based on real-time input from sensors.

CAM or computer aided manufacturing  is the use of computer software to control machine tools and related machinery in the manufacturing of workpieces.CAM also refer to the use of a computer to assist in all operations of a manufacturing plant, including planning, management, transportation and storage. Its primary purpose is to create a faster production process and components and tooling with more precise dimensions and material consistency, which in some cases, uses only the required amount of raw material and reducing energy consumption.

MRP or material requirement planning is a production planning and inventory control system used to manage manufacturing  processes. Most MRP systems are software-based, 

An MRP system is intended to simultaneously meet three objectives:Ensure materials and products are available for production and delivery to customers.Maintain the lowest possible level of inventory. Plan manufacturing activities, delivery schedules and purchasing activities.
