 The goal is to accomplish the production process in the smoothest, most-judicious and most-economic way.Production engineering 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, industrial engineering, and supply chain engineering.
