[[alternative]]Implementation of Computer Numerical Control Turning Center

碩士電機工程學系[[abstract]]摘要 Computer Numerical Control (CNC)複合加工機市場成熟，並已廣泛應用於汽機車、電機、電子和模具等製造業，而小型零件及精密長形工件，並不適合二次加工，因此對車銑複合化機台，使用尤其需要，就目前台灣車銑複合機，佔所有CNC加工機使用比率只佔31% ，大宗仍仰賴進口，因此本研究對小型、外型特殊且不適合用走刀式車床的工具零件，研製走心式CNC車床，除車削加工外，搭配銑削軸之動力刀具可進行外徑銑削與鑽削加工，達到複合加工的目的，以改良並提供客戶滿意需求為目的，提高CNC車銑中心機佔有率，減少國外進口機具比率。 本研究成品，經實際加工驗證，加工精度符合規範，其工件總加工完成時間與傳統加工比較，時間節省可達40%，機台成本節省與進口機台比較，預計節省20%，即使初期進口機台的品質較具優勢，但仍然可以期望本研究機台在市場具有競爭力。 關鍵字：CNC、複合加工機、走心式CNC車床[[abstract]]ABSTRACT The market of Computer Numerical Control (CNC) multiple tasking machining is already mature and it is widely used in the car, electric, electronic and mold industries. Because the small or precision-longtype workpieces are not suitable for cutting work by two different machines, they need to be operated by the specific multiple tasking machining very much. Currently this type of multiple tasking machining in Taiwan is only 31% of the total CNC cutting machines, and most of them are still imported. Therefore this study is focused on the small and special-form workpieces which are not suitable for “tool-moving-type turning machine” and provides the new idea of “center-moving-type turning and milling center.”(Swiss-type turning center) In addition to the turning work , with a power tool it can also do the milling and drilling work on the external diameter of the workpiece to combine different cutting processes at one machine , in hoping that this can raise customers’ satisfication of the aboved mentioned cutting works and increase the market share of the ”center-moving-type turning and milling center .”And also , it is hoped that in the future this type of imported machines can be replaced by domestic ones。 The practical cutting result proved that the precision of the workpiece of this study has fulfilled the specification . The total cutting time has been reduced 40% in comparison with the traditional cutting machine . The machine cost has been reduced about 20% comparing to imported machine , therefore even the imported machine has the quality advantage , it can still be expected that the study machine is competitive to imported in the market.
