| Summary: | 碩士 === 國立虎尾科技大學 === 動力機械工程系機械與機電工程碩士班 === 106 === The dry hobbing process is the most representative method in gear manufacture, which has grown rapidly recently. However, the studies on the reduced diameter of the tool after re-sharpening, with a changed meshing lead angle, and the accuracy of the generated gear were not found in the research of dry hobbing.
Therefore, experiments and analysis will be performed on the input lead angle of the hob cutter in the machine setting, due to the reduced diameter after re-sharpening in this study. The experimental study can improve the precision of hobbing tool design and machining. Moreover, introducing the concept of correcting lead angle to the gear manufacturing industry is helpful to the industry.
It is also found that the modification of tool lead angle input in the machine can improve gear cutting accuracy and tool life through the experimental study in this study. The design and analysis of experiments was applied to find out the optimum machining parameters for hobbing process. Compared with the previous methods that only rely on operators' experience, the optimum method saves blind test time and improves hobbing technology and efficiency.
