Manufacturing Cell
Product Families by Process:
Group Technology is a manufacturing technique in which the parts having similarities in geometry and/or manufacturing process are grouped together.
The group of similar parts is known as part family and the group of machineries used to process an individual part family is known as machine cell. It is not necessary for each part of a part family to be processed by every machine of corresponding machine cell. This type of manufacturing in which a part family is produced by a machine cell is known as cellular manufacturing.
Functional Production System:
” In Functional Manufacturing similar machines are placed close together (e.g. lathes, millers, drills etc.). Functional layouts are more robust to machine breakdowns, have common jigs and fixtures in the same area and supports high levels of demarcation. “
Functional Production System:
Cutting Deparment(5 Machines)
Welding Deparment(5 Machines)
Sandblasting Deparment(2 Machines)
Assembley Deparment(4 Workstations)
Painting Department(2 Workstations)
Finishing Department(4 Workstations)
Example :
Manufacturing Cell System:
“ Is based upon the principles of Group Technology. In Cellular Manufacturing systems machines are grouped together according to the families of parts produced. The major advantage is that material flow is significantly improved, which reduces the distance travelled by materials, inventory and cumulative lead times. Cellular Manufacturing employs setup reduction and gives the workers the tools to bemultiprocess, operating multiple processes, and multifunctional, owning quality improvements, waste reduction, and simple machine maintenance. This allows workers to easily self-balance within the cell while reducing lead times, resulting in the ability for companies to manufacture high quality products at a low cost, on time, and in a flexible way. “
