Construct an operations process diagram for manufacturing a rubber hose. The hose is constructed from a 1.83m long piece of rubber tubing; two ready-made bushings that are acquired and three machined parts. These pieces are what are illustrated in the figure. The hose is named with a, the ferrules with b with c a bayonet made of a brass tube and with d and e two pieces and inserts made from a brass rod. For him final assembly parts c and d are welded together and, with one of the bushings, assembled at one end of the hose. The part e and the second bushing are placed in the other extreme. The set, once finished, constitutes a flexible connection between the two parts of an inhaler. The bayonet c is made of brass tube and the first operation that is carried out for its elaboration is scraping and cutting; for this operation a time of 0.0130hr was used. The next operations is cut slot using a 0.0044hr field; after this suffer an inspection, to be sent later to be subassembled with the part c.

This insert is made up of brass rod and the operation performed on it is grinding, drilling and turning, using a time of 0.0340 hr. The next operation is TECHNOLOGICAL INSTITUTE OF HIGHER STUDIES OF THE COAL REGION deburring with a time of 0.0010hr; The part is then inspected and it is ready for the subassembly with the bayonet. The subassembly operation is called tube-to-tube welding. insertion; this takes a time of 0.19hr. The next operation is to nickel the set, doing this operation with workers paid by the day. This is then inspected subassembly to be sent to assemble the hose. The insert e is of brass rod and the operations that are needed for its elaboration are the following, drilling, turning and cutting, with a time of 0.470hr, milling groove at 0.0060hr, reburr with a time of 0.00600hr. after these operations inspection to order the nickel-plated parts to be nickel-plated, they are inspected and are ready for its assembly with the hose. The hose is made of rubber tube; first be inspected so that it does not have defects, the necessary length is immediately cut, using a period of time for this operation. of 0.100hr. At one end of the hose, the previously welded bayonet with the insert, using for this assembly one of the purchased bushings b and glue; paraca This operation uses a time of 0.400hr. The insert with the second cap and fixed with glue; this takes a time of 0.400 h. Finally I know Inspect the finished hose before sending it to the warehouse. All inspection per day.
