Analysis of Quality Improvement of Camshaft type K50 on the Reamer Process using DMAIC and FMEA Methods

The company of this researchis one the largest auto and motorcycle parts manufacturers in Indonesia. To support productivity demand from customers, Companyis divided into 2 plants, namely Cikarang plant Karawang plant. While production process is several departments, these departments production. In its duties, functions to control targets that have been set by minimize rejects production, with them producing K50 type Camshaft parts. Because part there are still many rejects, it necessary make improvements work order create good effectiveness efficiency. percentage reject reamer types do not enter pitch 83%, drill blows 9%, breaks 8%. Improving quality done using DMAIC method. purpose research. At stage D (Define) what determine Critical Quality (CTQ) tofind out physical characteristics K50. M (Measure) stage, measurements made a Pareto diagram find highest frequency defects which later need improvement. expected result product rejection.
