[연구목적] 본 연구는 급변하는 글로벌 기업경영환경에서 기업혁신의 방향을 제시하기 위해 제품혁신과 비즈니스 수익모델혁신이 지속가능 경쟁우위에 미치는 영향과 다시 지속가능 경쟁우위가 경영성과에 미치는 영향을 분석하는데 연구목적이 있다. [연구방법] 연구 분석은 국내 자동차 및 기계 제조 산업에 속하는 300개 기업을 표본으로 설문지를 통해서 수집된 247개의 자료를 활용하여 구조방정식모형을 사용하였다. [연구결과] 제품혁신은 지속가능 경쟁우위의 가치영역 중 제품지속성에만 유의한 영향을 미치며, 비즈니스 수익모델혁신은 제품지속성, 운영효율성 및 고객친밀성에 모두 유의한 영향을 보였다. 그리고 지속가능경쟁우위 가치영역 중에서 운영효율성은 시장성과 및 재무성과에 유의한 영향을 보였고, 고객친밀성은 시장성과에만 유의한 영향을 나타냈다. [연구의 시사점] 이러한 결과는 기업이 지속가능성을 확보하기 위해 제품혁신 뿐만 아니라, 비즈니스 수익모델혁신을 더욱 강화하는 것이 필요하다는 것을 보여준다. [Purpose] This study analyzes the effect of product innovation and business profit model innovation on a company’s sustainable competitive advantage, and to analyze the effect of sustainable competitive advantage on management performance again in order to suggest the direction of corporate innovation in the corporate management environment that is rapidly changing due to the recent development of Information Communication Technology. [Methodology] The study was conducted using a structural equation model using 247 data collected through a questionnaire as a sample of 300 companies belonging to the domestic automobile and machinery manufacturing industry. [Findings] The research results show that product innovation has a significant effect only on product leadership, and business profit model innovation has a significant effect on product leadership, operational excellence and customer intimacy. And among the factors of sustainable competitive advantage, operational excellence and customer intimacy were found to have a significant effect on financial and or marketing performance. [Implications] These results show that companies need to reinforce not only product innovation but also business profit model innovation in order to secure sustainability.

Recently, parallel kinematic machine tool with high accuracy and stiffness is causing great concern in 5-Axis processing which is applied in manufacturing with complicated shape products. However, there are some inherent difficulties in parallel kinematic machine tool such as a collision between workpiece and tool, over-cut and under-cut, verification of tool path route in progress. To solve these problem in advance, it needs machine simulation of parallel kinematic machine tool above all things. the purpose of this study is, therefore, carried out machine simulation for parallel kinematic machine tool and accumulation of technical knowledge for the productivity and efficiency in parallel kinematic machine tool through verification of 5-Axis machining.

For this study, the domestically developed bootstrap reservoir of the aircraft is set up in accordance with the temperature and humidity conditions depicted on the qualification test, and the variation in the internal pressure of the bootstrap reservoir of the aircraft is examined. The study shows that the bootstrap reservoir has less variation in the internal pressure at room temperature than at low temperature(-40℃). As a result, the internal pressure can be maintained stably when the temperature of working fluid in the bootstrap reservoir and the atmosphere environment is over room temperature(25℃). Therefore the keeping of temperature above room temperature is very important to operate the bootstrap reservoir of the aircraft properly.

This research deals with evaluation of machining accuracy for Parallel Kinematic Machine Tool(PKMT) applied parallel type robot system with high precision and stiffness. For this purpose, machine simulation is carried out to foreknow collision and interference between workpiece and tool. Furthermore, on the basis of machine simulation data, PKMT is manufactured. Machining accuracy such as cylindricity straightness, squareness, parallelism circularity, concentricity pitch error and yaw error, is measured by using coordinate measuring machine. Test piece for evaluation of machining accuracy is designed and manufactured under the standard of ISO 10791-7.
