In this study, we developed the fuel pump valve on MC-C type ship engine. We examined the 7 kinds performance of valve through three-dimensional measuring machine and surface roughness. It showed better performance than the spec. We measured the chemical component of valve materials. It was suitable for the material standard value. Also we measured the hardness of heat-treated parts on valve. It was suitable for the hardness standard value. When the designed valve made a prototype, there's nothing problem and the development was successful.

SNCM420 steel is one of the cam shaft materials which are used in the supply unit for ship engine cam shaft. In this study the assessment of cutting behavior was conducted for the SNCM 420 steel and SM45C steel with various cutting conditions as depth of cut 0.5, 1.0, 1.5, 2.0mm and feed rate 0.1~0.3m/rev. The controlled chip was produced in feed rate 0.2, depth of cut 1.0 for SNCM420 and feed rate 0.2, depth of cut 2.0 for SM45C. There is no difference cutting force between SM45C and SNCM420 steels.

본 연구에서는 자동차 자동변속기의 신개발 부품인 헬리컬 단조금형의 다양한 윤활제에 따른 타르이볼로지적 특성을 연구하였다. 윤활제는 점성계수가 다른 5가지를 사용하였으며, 비교 평가를 위하여 공기 중에의 마찰 마멸 실험을 행하였다. 마찰 마멸 실험은 pin-on-disk 형태의 시험기를 사용하였으며, 하중은 20-100N의 범위로 하였고 속도는 0.06-0.34m/s의 범위에서 실험을 행하였다. 마찰실험을 행한 결과 L-1, L-2, L-4, L-5와 같이 높은 점성을 가진 윤활제를 사용하였을 때, 속도가 증가함에 따라 마찰계수도 증가하는 경향을 보이고 있다. 반면, L-3와 같이 점성이 낮은 윤활제를 사용하였을 때에는 속도가 증가함에 따라 마찰계수가 감소하는 경향을 나타내고 있다. The purpose of this study is to find of tribologic characteristics on the various lubricants in helical forging mold which is new development part in mobile auto-transmission. There are 5-kinds of lubricant in which are different from in viscosity coefficient. This study has used the pin-on-disk type of friction wear test system and has used the normal load in the range of 20-100N. It was operated at the speed range of 0.06-0.34m/s. The friction coefficient in the higher kinematic viscosity oils which were L-1, L-2, L-4 and L-5 tends to increase slowly as the velocity increase. In low kinematic viscosity oil L-3, the friction coefficient tends to decrease as the velocity increase.

The purpose of this study is to find of friction characteristics on the coating conditions in cold forging of helical gear which is new development part in mobile auto-transmission. There are 3-kinds of coating conditions which are Co1, Co2 and Co3 containing S. This study has used the pin-on-disk type of friction wear test system. It was operated at the load range of 20-100N and at the velocity range of 0.06-0.34㎧. As a result of friction, the friction coefficient is low in friction of SM45C and Co2, Co1 and Co1, Co1 and Co3. In load of 20N, the friction coefficient is high value different with other loads. The friction coefficient tends to decrease as the velocity increase.
