### Toy pig assembly - Methods Engineering

1. 1. TOY PIG Assembly By group 5: Angelica Agacita Fruilene Isabel Panes Lanmark Mabasa Ian Nilo Andales
2. 2. Objectives :At the end of the activity the students are expected to:• Apply the concept of hand and motion economy as well as the use of therbligs in the study• Analyze every step in the toy pig assembly process• Make an effective data sheet• Make use of predetermine time standard
3. 3. workertoy pig
4. 4. Apparatus : nosebody feet face
5. 5. Procedure:• Prepare the parts of toy pig to be assembled• Assign a worker to perform the experiment (the toy pig assembly)• Create a workstation that is the best workstation in assembling the toy pig• Make a data sheet containing left and right hand chart, therbligs, including the descriptions of every motion of the worker and standard time of assembly by using PTSS• After creating the best workstation and the data sheet, perform now the experiment (the toy pig assembly)
6. 6. • While the worker performs, make an observation , do the time study and record the motions of the worker.• Fill the data sheet with the information gathered.• Compute the units that a worker can finish on a day(8hrs).• Publish the results.
7. 7. What is Predetermined TimeStandard?
8. 8. Theoretical Background• MTM (Mynard, Stegemerten & Schwab, 1948) gives time values for the fundamental motions of reach, move, turn, grasp, position, disengage and release. The author defined MTM as “a procedure which analyzes any manual operation or method into the basic motion required to perform it, and assigns to each motion a pre-determined time standard which is determined by the nature of the motion and the conditions under which it is made.”• Provides detailed information of the work elements (Groover,2007)
9. 9. Theoretical Background• Experience has proved that companies that have developed sound standards based on measurement are more likely to meet scheduled delivery dates for their products.• The use of PTS allows the introduction of up – to – date production control procedure, with the resulting advantage to customers who get their merchandise when they want and need it.• Also, it tends to make any company more time – and – cost conscious; this usually results in lower selling prices.(Freivalds, et.al)
10. 10. Theoretical background• In measuring the time standard, you must take the step-by-step procedure.1. Select the job to study2. Collect information about the job3. Divide the job into elements4. Do the actual time study5. Extend the time study6. Determine the number of cycles to be timed7. Rate, level and normalize the operator’s performance8. Apply allowances9. Check for logic10. Publish the time standard

22. 22. Analysis: STRENGHTS• Principle 1: The two hands should begin as well as complete their motions at the same time.• Principle 2: The two hand should not be idle at the same time except during rest periods. Both hands were able to balance the motions where it also able to complete the assembly of the two toy pigs
23. 23. • PRINCIPLE 3: Motion of the arms should be made in opposite and symmetrical directions and should be made simultaneously.The two hands were able to complete the task and its usewere made effectively. It can be seen from the simo chart thatthe hands were functioning and the task are balanced.
24. 24. • PRINCIPLE 8: Work should be arranged to permit easy and natural rhythm wherever possible.• PRINCIPLE 9: Eye fixations should be as few and as close together as possible.The work of the worker permits easy and natural rhythm because thearrangement of the parts were made according to the distribution of thetask for the hands. The parts were located in away that the operator canreach without stretching or causing so much effort in assembling the toypig. With these the eye fixations are made few.
25. 25. • Principle 10: There should be a definite and fixed place for all tools and materials.• Principle 11: Tool, materials, and controls should be located close to the point of use. The materials used in assembling the toy ship are readily available for the worker’s reach. The distances were made according to the anthropometric measurements or capability of the operator to reach and work.
26. 26. • Principle 16: The height of the workplace and the chair should preferably be arranged so that the alternate sitting and standing are easily possible.The chair and the working table were provided in a way thatthe worker is comfortable to use it. The height does notpermit the operator to work in a restricted motions.
27. 27. • Principle 18: The hands should relieved of all work that can be done more advantageously by a jig, a fixture, or a foot - operated device.• The jigs were provided not only to make the operator work effectively but as well to finish the two toy pigs at the same time. As well, the jigs would not affect the quality of the output.
28. 28. COST-BENEFIT ANALYSIS TOOLS COST BENEFIT P 50.00 The operator will no longer hold the JIG 1 parts of the toy pig. *For the purchase, the management may JIG 2 P 50.00 contact a furniture maker and ask to make the designed jigs with a fixed cost of P 50.00 each. The operator will have a chance to take chair P 1,229 a rest after long hours of standing The working table will be utilized for TABLE P 351.00 the assembly of the toy pigsACRYLIC BIN (P 49/ pc.)

29. 29. ConclusionPredetermined time standard system is used to establish time standard in completing acertain job or any given process. Advantages includes no disruption of the operation duringthe study and the standards can be established. They are not too difficult to apply and canbe less time consuming than other methods when time standards are determined. They areparticularly useful for very short repetitive time cycles such as assembly work in the toyindustry. Establishing time standard may help the company identify the part of assemblythat needs improvement. This will also help the company maximize the time of each workerworking on a certain assembly thus improving the productivity that will increase the profitof the company.
