Present CAM technology cannot provide important physical property such as cutting farce and machined surface. Thus, the selection of cutting conditions still depends on the experience of an expert or on the machining data handbook in spite of the developed CAM technology. This paper presents an advanced methodology to help the worker to determine optimum cutting condition for CHC machining that excludes the need for expertise of machining data handbook. The virtual machining system presented in this paper can simulate the real machining states such as cutting farce and machined surface error. And virtual machining system can schedule feed rate to adjust the cutting force to the reference force.

현재 대부분의 교육현장에서는 학생들을 지도하기 위해 기본정보가 기록되어 있는 노트용 교무수첩과 전자교무 수첩을 병행하여 사용하고 있다. 전자교무수첩은 정보를 관리하기 위해 업무용 데스크탑 PC가 대부분으로 휴대성이 어려워 활용도는 아주 미약하다. 본 논문에서는 기존 교무수첩을 스마트폰에 탑재해서 언제 어디서든 장소나 시간에 구해 받지 않고 학생 정보를 조회하여 학생들을 지도 할 수 있는 스마트 교무수첩 시스템을 설계하였다.

The Summary Handbook of Acupuncture and Moxibustion (鍼灸要覽) (SHAM) was written by an unknown folk healer who learned acupuncture about 100 years ago in Korea. The book discusses 79 acupoints and includes a table of contents, a text, and a pair of acupoint charts. The acupoints in the book are classed under two headings, 49 acupoints of 14 meridians and 33 acupoints. A number of the acupoints such as Gichoong (氣忠), Eumheobong (陰虛峰), Goowa (口卧), Cheonryang (天良) did not fit the then existing meridian system and were newly uncovered by the authors. The book also discusses needle insertion depth in a way that is quite different from how insertion depth is understood by clinicians today. Books such as SHAM that record new acupoints and treatments are rare among Korea's existing medical and clinical books and can be said to be very important in terms of medical history.

In determining optimal cutting condition for face milling operation, tool wear is an important factor. For the purpose of establishing the relationship between various machining factors and tool wear, cutting tests have been performed. As a result, hardness and chemical composition of workpiece material, chemical composition and grain size of cutting tool and cutting speed have been selected as machining factors. In addition, relationship between feed rate and workpiece hardness has been observed. Prior to utilizing cutting conditions recommended by ‘Machining Data Handbook(MDH)’ as a knowledge base, an analysis for the validity of the MDH has been provided. Based on this analysis, tool life criteria applied by MDH has been modified. Finally, using MDH recommended data for neural network trainning, the results from the trained neural network for optimal cutting condition for some given workpiece and cutting tool can be used as reference cutting conditions.
