| Summary: | 碩士 === 國立雲林科技大學 === 工業工程與管理系 === 107 === The high-frequency induction heat treatment process, the parameters of the frequency, power, temperature, time, size and other parameters of the workpiece after induction heat treatment are judged by experience. Without standardization adjustment specification reference, the quality of the workpiece is uncontrollable after each heat treatment.
In this study, the heat treatment parameters were optimized using the Taguchi method. The material JIS55, the profiled shape (diameter 20 * 20mm) profiled steel, is optimized for the machining parameters at the workpiece positions S1 to S4 on each heated surface
After the research, it is found that the maximum SN ratio of the best parameters is: A2B3C3D2E1. Because it is difficult to narrow the variation on the field production line than the target value, this experiment has a two-stage design, and the two-stage optimization parameters obtained by the study are obtained. For, A2, B3, C2, D2, E1 The optimal parameters obtained in this study are A2 quenching power 17 (KW), B3 quenching liquid concentration 25 (%), C2 quenching rate 30 (mm/s), D2 holding Temperature time 830 (°C), E1 tempering power, the control factor is B quenching liquid concentration and D holding temperature time, the most significant effect, and C quenching rate, can still be used as adjustment in material content defects, and A, The E factor effect is minimal to reduce costs and man hours.
