Production Engineering

shape Introduction

What is Production Engineering? Production Engineering is a combination of manufacturing technology, engineering sciences with management science. In a broad sense, Production Engineering is the subset / specialization of Mechanical Engineering with the focus only on Machine Tools, Materials Science, Tribology, and Quality Control. A production engineer is responsible for all aspect of the design, development, implementation, operation and management of manufacturing system. Product Engineers are key personnel in manufacturing organizations. Below are some of the crucial responsibilities of a Production Engineer.
  • Production Engineers are responsible for planning & scheduling the production in any manufacturing industry. [e.g. Automobile Manufacturing industry].

  • Production Engineers are responsible for quality control, distribution and inventory control.

  • Production Engineers will be programming the Computer Numerical Control - CNC machines to produce engineering components such as gears, screws, bolts, etc.

  • Production Engineers use machine tools, materials and human resources in the most effective way to produce any goods.
