Six Sigma (6σ) is a set of techniques and tools for process improvement.It was introduced by American engineer Bill Smith while working at Motorola in 1986. [1] [2]Six Sigma strategies seek to improve manufacturing quality by identifying and removing the causes of defects and minimizing variability in manufacturing and business processes.
A modern automobile assembly line. Mass production, also known as flow production, series production, series manufacture, or continuous production, is the production of substantial amounts of standardized products in a constant flow, including and especially on assembly lines.
Batch production is the method used to produce or process any product of the groups or batches where the products in the batch go through the whole production process together. An example would be when a bakery produces each different type of bread separately and each product (in this case, bread) is not produced continuously.
This process is known as insert moulding and allows single parts to contain multiple materials. This process is often used to create plastic parts with protruding metal screws so they can be fastened and unfastened repeatedly. This technique can also be used for In-mould labelling and film lids may also be attached to moulded plastic containers.
A First Article Inspection (FAI) is a production validation process for verifying that a new or modified production process produces conforming parts that meet the manufacturing specification detailed in technical or engineering drawings. Typically, a supplier performs the FAI and the purchaser reviews the report.
The engineering design process, also known as the engineering method, is a common series of steps that engineers use in creating functional products and processes. The process is highly iterative – parts of the process often need to be repeated many times before another can be entered – though the part(s) that get iterated and the number of such cycles in any given project may vary.
In the manufacturing batch production process, the machines are in chronological order directly related to the manufacturing process. The batch production method is also used so any temporary changes or modifications can be made to the product if necessary during the manufacturing process. [3]
