Productivity Analysis of Material Handling for Machining Operation - Operation Analysis Step

Productivity Analysis - Comparison of Current Process to Ideal or the Best Process has to be done from System level up to Element level. 

Lesson 94 of Industrial Engineering ONLINE Course.

Lesson 95. Operator Self Inspection Devices - Processing Operation Productivity Analysis Step.


Part of Main Topic: Analysis of Items in Operation Information Sheet


IISE Course - MATERIALS HANDLING ANALYSIS

http://nraoiekc.blogspot.com/2021/07/iise-course-materials-handling-analysis.html


The  course gives equal weight to facility and warehouse subjects. It is needed by those who have to apply the following procedures:

Replace materials handling equipment, improve or add to their specifications.

Replace materials handling methods, or evaluate alternative methods.

Reorganize for a better flow of materials and movement of products.

Reduce costs through better materials handling methods.

Questions for Analysis



How is the material moved from the earlier machine to the current machine?

Is an  operator required to pick up the work piece and stack it?

Where are the work pieces stacked?

What is the motion pattern used by the operator to load the work piece?

What is the motion pattern used by the operator to unload the work piece?

Does he need to stack it?

Does he have a role in placing the finished item stack in the next material handling movement from his workstation?

More detailed treatment


As a stimulation to all kinds of material- handling improvement, the following questions should be answered by the analyst during the course of his study of the factor of material handling.





1. Is the time consumed in bringing the material to the work station and in removing it large in proportion to the time required to handle it at the work station?

2. If not, should material handling be done by operators to provide rest through change of occupation?

3. Should hand trucks be used?

4. Should electric trucks be used?

o. Should special racks or trays be designed to permit handling the material easily and without damage?

6. Where should incoming and outgoing material be located with respect to the work station?

7. Is a conveyer justified?

8. If so, what type would best be suited to the job?

9. Can the work stations for the successive steps of the process be moved close together and material handling accomplished by means of gravity chutes?

10. Can the operation be done on the conveyer?

11. Can a progressive assembly line be set up?

12. Can material be pushed from operator to operator along the surface of the bench?

13. Can material be dispatched from a central point by conveyer?

14. Can material be brought to a central inspection point by conveyer?

15. Can weighing scales be incorporated to advantage in the conveyer?

16. Is the size of the material container suitable for the amount of material transported?

17. Can container be designed to make material more accessible?

18. Can container be placed at work station without removing material?

19. Can electric or air hoist or other lifting device be used to advantage at work station?

20. If overhead traveling crane is used, is service rendered prompt and adequate?

21. Can a pneumatic tube system be used to convey small parts or orders and paper work?

22. Will signals such as lights or bells notifying move men that material is ready for transportation improve service?

23. Can a tractor-trailer train running on a definite schedule be used?

24- Can an industrial railway running on tracks be used?

25. Can tractor-trailer or industrial railway system be replaced by a conveyer?

26. If helper is needed to handle large parts at work station, can a mechanical handling means be substituted?

27. Can gravity be utilized by starting first operation of a series at higher than floor level?

28. Can scrap or waste material be handled more effectively?

29. Can departmental layout be changed to improve material- handling situation?

30. Should the material-handling problem in general receive more intensive study in the immediate future?
