Abstract:

Conclusions The effect of experimental error on the determination of the minimum-cost cutting speed was investigated using the concept of statistical inference. The theoretical cutting speed for minimum cost Vmin is not uniquely defined, but lies within a probable range of speeds because of the uncertainty in the parameter-estimates of the tool-life equation. The confidence interval for Vmin depends on the magnitude of the cost-time parameter t sub e as t sub e increases, the Vmin confidence interval decreases. The confidence interval for Vmin is affected by the experimental range of feed in tool-life testing the smallest confidence interval is at the average experimental feed. A decision rule based on the minimax principle is used to illustrate the selection of a specific speed from within the Vmin confidence interval. Author
