摘要:

In this paper a test method for time study developed from a theoretical basis of sequential analysis of mathematical statistics is presented. This method admits a statistical decision on the regions which contain a certain time ratio.

摘要:

This paper presents a theory and related experiments on centrifugal barrel finishing. A calculation for the centrifugal force in the barrel is described. The limitation of the ratio between the rotation speed of the tubs and turrets, and values of polishing efficiency are determined by the calculation and compared with experimental results. It can be understood from the results why the polishing efficiency of the centrifugal barrel is far higher than that of the ordinary rotating barrel. Finally some considerations on design criteria are mentioned.

摘要:

In this paper the Filon's transformed equations have been applied successfully to evaluate the chip-tool interface stresses of a cutting tool from the photo-elastic data. This method is shown to be advantageous over the shear difference method, particularly for negative rake tools. The analysis was carried out to study the effect of rake angle and depth of cut on the stress distribution and total forces on the rake face, involved in the orthogonal machining process.

摘要:

This paper describes research performed to determine the effect of cutting fluid on first cut surface finish in single point turning. A measure of cutting fluid lubricity was used as an independent variable as well as cutting speed, tool feed, depth of cut and replications. The dependent variable was surface roughness. Though cutting medium was not a significant main factor, it was highly significant in several interactions with the other variables.

摘要:

This paper examines the relationship between the utility of money and the disutility of work. This relationship is then established as a foundation for the construction of a general theoretical model which may be used to design or evaluate certain classes of incentive wage structures.

摘要:

This study deals with the problem of optimum production scheduling. The problem is solved in detail by a discrete form of Pontryagin's maximum principle to illustrate the use of the principle.
