Answer 1

STEP1:Examples of Manufacturing System Single-station cells Machine clusters Manual congregation lines Automated transport lines Automated congregation system Machine cell (cellular built-up)Flexible manufacturing systems Components of a urbanized System: Production machines Material conduct system Computer arrangement to coordinate and/or organize the earlier components Human personnel to run and order the system Classification of create machines: Manually operate machinery be forbidden or supervised by a being worker Semi-automated machinery perform a portion of the work cycle underneath a number of form of plan have power over, and a worker tends the contraption the rest of the cycle Fully automated machines operate for comprehensive age of time with no human attention

STEP 2 :4.array of mechanized system based on Part or merchandise mixture:“The point to which the structure is capable of dealing with variations in the parts or products it produces ”Three cases: Single-model box - all parts or yield are identical (enough command/fixed mechanization)Batch-model box - different part or products are produced by the system, but they are produced in batches because changeovers are required (hard merchandise variety)Mixed-model case - different parts or products are produced by the system, but the system can handle the differences without the need for slow changes in net (yielding product diversity)

STEP 3:4.2.urbanized process are the ladder through which raw materials are distorted into a final product. The developed process begin with the formation of the materials from which the plan is made. These materials are then modified through manufacturing processes to become the required part. Manufacturing processes can comprise treating such as heat treating or coating, machining, or reshaping the material. The manufacturing process also includes tests and checks for quality oath throughout or after the built-up, and growth the production succession past to gentleman factur

STEP 4:4.2.3Cellular industrialized is a man process that produce family of parts delimited by a solitary line or cell of machinery operate by machinists who work only top secret by the line or cell.

A cell is a small height, clearly-defined produce unit in a larger plant. This unit has sum responsibility for producing a relations of like parts or a product.

All necessary gear and manpower are restricted in this cubicle, so giving it a level of ready sovereignty. The primary step in implementing cellular developed is to break down the various items bent by the company into a number of panel sets or family.

The agreement course of action (collection skill) involve identify items with likeness in design characteristics or developed uniqueness, and assemblage them hooked on part people. intend characteristics comprise size, outline, and function; developed characteristics or process independence are base on the nature as well as sequence of operations obligatory.

In many cases, though not always, the two kinds of individualism are associated. thus design families may be visibly unlike from meting out families. just the once recognized, similar items can be classified into family. Then a categorization is developed that facilitates retrieval from a design and manufacturing file.

For model, the scheme can be second hand to determine if an identical or similar part exists before a completely new part is designed. If a similar part is establish, it may be that a easy modification would produce satisfactory consequences without the expense of new part devise.

Similarly, arrangement the manufacturing of a new part after matching it with an existing part family can eliminate new and costly processing requirements. This grouping of part or manufactured goods families require a systematic analysis that often proves to be a major undertaking.

Usually, there is a considerable amount of data to analyze, and this in turn be able en route for be relatively lingering and costly. Three primary method exis
