TAYLOR - NARAYANA RAO PRINCIPLES OF INDUSTRIAL ENGINEERING
|4-Machine Utilization Economy|
Resource Utilization Economy Principles
The principle can be restated better more appropriately. "Principles of resource utilization economy to be developed for all resources used in engineering systems." (Added on 9 June 2018).
Utilization economy principles are to be developed for each resource used in the production processes. So far, in industrial engineering discipline, principles of motion economy only are deveoped. There has to be research and effort to develop similar principles for all resources.

Principles of Machine Productivity - F.W. Taylor
1. A careful study is to made of the time required to do each of the many elementary operations of machining of components manufactured in the establishment.
2.These elementary operations are then classified, recorded, and indexed, and when work is to be done, the job is first divided into its elementary operations, the time required to do each elementary operation is found from the records, and the total time for the job is summed up from these data.
3. This method is more effective than the method of estimating the time based on time taken to do whole jobs of similar components.
4. To implement the principles, in the case of work done by metal-cutting tools, such as lathes, planers, boring mills, etc., F.W. Taylor undertook a long and expensive series of experiments to determine, formulate, and finally practically apply to each machine the law governing the proper cutting speed of tools, namely, the effect on the cutting speed of altering any one of the following variables : the shape of the tool (i.e., lip angle, clearance angle, and the line of the cutting edge), the duration of the cut, the quality or hardness of the metal being cut, the depth of the cut, and the thickness of the feed or shaving.
5. The careful study of the capabilities of the machines and the analysis of the speeds at which they must run is to be made.
6. Defects or shortcoming in machines will be realized when the best methods of cutting metals are determined and the necessary modifications have to be made, if possible. Otherwise, replacement needs to be done at the earliest economic opportunity.
7. Systematization of many small details in the running of the machine shop, such as the care of belting, the proper shape for cutting tools, and the dressing, grinding, and issuing tools, oiling machines, issuing orders for work, and a host of other minor methods and processes which may waste a machinist's time or machine time.
8. The care of the equipment is to be improved.
