中文摘要 | 本文銑削葉輪葉片面在精削製程採用的五軸加工法,包括五軸貼面側銑法、五軸等參數路徑分層銑法、五軸平行路徑分層銑法。採用刀具皆為ψ4球端銑刀。加工材料為7075鋁合金。經實作切削及應用三次元量床以直接法(direct method)量測曲面形狀誤差分析,在三次元量床檢測加工精度比較結果,三種加工法加工精度相差不大,最大誤差(過切)在0.03mm內,五軸貼面側銑法加工時間最經濟,但在葉片面扭曲大的地方會產生較大的誤差及易產生顫動影響表面精度,後兩種方法尺寸誤差較平均,且有較佳的表面粗糙度,尤其以平行路徑分層銑法為佳,但加工路徑長,較耗時。 |
英文摘要 | In this paper, three five-axis milling processes, five-axis side milling process, five-axis Iso-parametric tool path process and five-axis parallel tool path process, were adopted for impeller blade surface finish machining. An ball end mill cutter with diameter 4 mm was used for these three milling processes. All the machined blade surfaces were measured by using coordinate measuring machine (CMM) with direct method of curve surface error measuring to identify the accuracy of the machined blade surfaces. The machining and measuring results show that all these three processes can obtain good machining accuracy. And the maximum dimensional errors of the three processes were within 0.03 mm. The five-axis side milling process appears larger dimensional error on the larger distorted of the blade surface than another two processes. |
