CIM Unit 1: Introduction to Computer Integrated Manufacturing

The primary elements of CIM are Design, Production Planning, Production, and Control, which are interconnected and integrated through the CIM wheel, enabling efficient and automated manufacturing processes.

Automation refers to the use of machines or computers to perform specific tasks, whereas CIM integrates automation with other manufacturing functions, such as design and production planning, to create a comprehensive and efficient manufacturing system.

The four Islands of automation are CAD, CAM, FMS, and Robotics, which work together to automate and integrate various manufacturing functions, such as design, production, and quality control.

CIM brings about significant technological change by integrating and automating various manufacturing functions, enabling the production of high-quality products at reduced costs and improved efficiency, with benefits including increased competitiveness and improved customer satisfaction.

CIM offers several advantages, including improved productivity, reduced costs, enhanced product quality, and increased flexibility, by integrating and automating various manufacturing functions.

PDM is a critical component of CIM, managing and integrating product data throughout the product life cycle, from design to production and distribution, ensuring data consistency and reducing errors.

Machine tools, material handling systems, computer control systems, and other ancillary equipment.

CAPP is a computer-based system that provides assistance in planning and managing the manufacturing process. Its benefits include improved productivity, reduced lead time, and increased accuracy.

The logical steps in CAPP include process planning, tool selection, operation sequencing, tolerance analysis, and process optimization.

A composite part is a part that consists of multiple individual parts or components that are assembled together to form a single unit.

Improved accuracy and efficiency in inspection and quality control processes.

MRP is a computer-based production planning and inventory control system. Its inputs include master production schedule, inventory, and bill of materials. It works by calculating material requirements and generating purchase and production orders. Outputs include material forecasts, purchase orders, and production schedules. Benefits include reduced inventory levels, improved delivery performance, and increased productivity.

MRP II is an extension of MRP that integrates all aspects of the organization, including finance, human resources, and marketing, in addition to production planning and inventory control. It differs from MRP in that it includes additional modules for capacity planning, shop floor control, and quality control.

To manage and monitor the production process in real-time.

Improved production efficiency, reduced material handling, and increased flexibility.

CAPS is a computer-based system that uses algorithms and mathematical models to schedule production and allocate resources. It helps in reducing production time, improving machine utilization, and increasing productivity.

ERP is an integrated software solution that manages all aspects of an organization, including finance, human resources, production planning, and supply chain management. Its advantages include improved efficiency, reduced costs, and increased customer satisfaction.

To generate a 5-digit form code that represents the geometric features of a part.

A Hub is a simple network device that connects multiple devices together and forwards incoming data packets to all devices connected to it.

A subroutine is a set of instructions that can be called repeatedly from different parts of a program to perform a specific task or function.

A Switch operates at the data link layer (Layer 2) and forwards data based on MAC addresses, while a Router operates at the network layer (Layer 3) and forwards data based on IP addresses.

The G28 code is used to specify the position of the spindle during a CNC machining operation.

A CNC part program is a complete program that specifies the machining operations required to manufacture a part, while a subroutine is a set of instructions that can be called repeatedly from different parts of a program.

The G02 code is used to specify a clockwise circular interpolation motion in a CNC machining operation.

Core technologies include AI, IoT, robotics, and Big Data analytics, which enable smart factories through automation, real-time monitoring, and data-driven decision-making.

Industry 4.0 focuses on automation and efficiency, while Industry 5.0 emphasizes human-centered innovation, collaboration, and social impact, highlighting the need for a more holistic approach to industrial development.

IoT applications enhance manufacturing processes by enabling real-time monitoring, predictive maintenance, and supply chain optimization, with examples including smart sensors, RFID tracking, and machine learning-powered quality control.

Big Data and Cloud Computing enable IoT-enabled manufacturing by providing scalable storage and processing capabilities, benefits include improved analytics and scalability, while limitations include data security and integration challenges.

CPMS integrate physical and computational systems through IoT, AI, and robotics, enabling real-time monitoring, prediction, and optimization, with applications in smart manufacturing, predictive maintenance, and supply chain optimization.

Digital Twin technology creates virtual replicas of physical systems, enabling real-time testing, simulation, and optimization, improving product design, development, and production through reduced prototyping and increased efficiency.
