摘要
對高速高精度工具機或PCB板鑽孔機而言,進給系統加速度提升,意味著驅使平台加速的螺桿軸向力變大,其反作用力透過止推軸承對機器結構造成的振動量也隨之增加。因此為了提升加工精度,除了對進給系統動態加以分析,尚須考慮各結構間的相對振動行為,確認需加強的元件部位並建立設計規範。
本論文首先探討鑽孔機高速定位時,平台動態特性受控制器濾波參數之影響及路徑規劃加速度設定與所選用的馬達之關係。其次,由於鑽孔機主軸轉速不斷提高,本論文也探討高速轉子在平台振動(轉動座標系)下的影響。最後,高加減速鑽孔機形狀設計除了考量尺寸搭配與靜力變形外,機台重心位置也是影響平台定位精度之重要參數。
本論文建立了高速鑽孔機進給系統的動態模型,以及高速鑽孔機的結構模型,並以Matlab與BCB兩套軟體為發展平台設計電腦輔助分析軟體,協助系統設計者分析鑽孔機在實際工作狀態下的行為,使設計者在設計時能準確地掌握各元件的動態行為,減少新機的測試修改時間。
