Overview

Course Overview: Production technology is a combination of manufacturing technology with management science. A production engineer typically has a wide knowledge of engineering practices and is aware of the management challenges related to production. The goal is to accomplish the production process in the smoothest, most-judicious and most-economic way.

Production technology encompasses the application of castings, machining processing, joining processes, metal cutting & tool design, metrology, machine tools, machining systems, automation, jigs and fixtures, die and mould design, material science, design of automobile parts, and machine designing and manufacturing. Production engineering also overlaps substantially with manufacturing engineering and industrial engineering.

In industry, once the design is realized, production engineering concepts regarding work- study, ergonomics, operation research, manufacturing management, materials management, production planning, etc., play important roles in efficient production processes. These deal with integrated design and efficient planning of the entire manufacturing system, which is becoming increasingly complex with the emergence of sophisticated production methods and control systems.

Course objectives:

• 1. To reorganization of Practical orientation of Manufacturing Processes
• 2. Understand the basic parameters in the foundry section to producing various metallic parts.
• 3. Knowledge on different kinds of Production Processes and practices available for Shaping or Molding several daily used parts for industries.
• 4. Equipment selection for various deformation Processes will be understood.
• 5. Understand the various methods used to producing plastic shapes.

Course Outcomes:

• 1. An ability to contrast the different types of manufacturing process and apply the Technology Systems Model to manufacturing identify, illustrate, solve, formulate, distinguish & compare different working Process
• 2. An Ability to understand the design a system, component or process to meet desired needs within, realistic constraints such as manufacturability, economic, environmental, safety & sustainability etc.,
• 3. An ability to apply knowledge of mathematics, science, and engineering, to Identify, define, and clearly state a manufacturing design problem.
• 4. An ability to identify, formulates, analyzes, and solves Engineering Problems in Optimum time and ability to demonstrate ability to welding and conduct experiments, analyze and interpret data.
• 5. An ability to use the techniques, skills and modern engineering tools necessary for engineering practice with the concept of virtual work. Recognition of the need for, and an ability to engage in self education and life-long learning.
