When developing machining processes, it is necessary to select the optimum machining conditions (such as tool conditions, cutting speed or feeding speed), as well as select an efficient machine and process to be used. Quality engineering methodology recommends evaluating the performance of machining milling or drilling processes by directly or indirectly observing the energy consumption. In this study, the evaluation of machining a stainless steel part was made by measuring the total power consumption of the main motor. However, the gain was not very reproducible. Therefore, the variation of the energy consumed during idling time was included in evaluation. The results showed a good reproducibility of gain. Under the optimum conditions, the dimensions after machining were uniform and the surface roughness was also improved.

In the era of diversified information, the demand of electronic document processing is becoming stronger and stronger. Today, it is indispensable to use electronics for data base processing. The methods transforming printed documents into electronic codes have been commercialized, however, technologies to recognize hand writing have not been well developed yet. In this paper, the improvement of hand writing recognition, which is to recognize the pattern of multi-dimensional information, was studied using MTS (Mahalanobis-Taguchi System). It has been confirmed the application of MTS is effective for multi-dimensional information. This study aimed to apply the method to a new field of multi-dimensional information processing.
