제안 방법
- On the basis of the analysis for noise performance in the machining process parameters respectively, a group of optimized machining process parameters is obtained. And then, 2 ball screws were produced again with present machining process parameters and optimized machining process parameters respectively to do noise tests to show how noise performance improved. At last, surface roughness tests were done to know how surface roughness is improved on optimum and present ball screws as the noise decreasing reason.
- Even if most machining process parameters were confirmed by experiments and tests, nearly all parameters were adjusted by experience. In this study, machining process parameters were evaluated in respects of technical, business, produce and quality to verify which impacts on noise most. Nut dressing rpm, shaft grinding wheel rpm, shaft dressing rpm, shaft principal axis rpm, nut spindle rpm, shaft taper level have been selected as test elements with which scores the most points.
대상 데이터
- With the present parameters benchmark, respectively, two groups of parameters were set. Based on the above data, 18 different ball screws have been produced as test specimens.
