A Study of Electric Power Evaluation of a Boring Process by Use of Interval Analysis

Abstract

The application of interval analysis to parameter design for a boring process evaluated by use of electric power data is proposed. The purpose is to use interval analysis to obtain different findings. In contrast to the factor effects previously used in the analysis of electric power evaluation, the factor effects obtained by analysis during the boring process, at the start of the boring process, and at the end of the boring process were compared. As a result it became possible to analyze the variance over different intervals, and express the evaluation of the boring process in more detail according to the stage of the boring operation.
