- 自動換刀系統設計論文數控車床將向中高檔發展，對數控刀架需求量將大大增加。隨著數控車床的發展，數控刀架也向快速換刀、電液組合驅動和伺服驅動方向發展。
本設計采用電液組合驅動，主要完成了八工位臥式刀架的機械結構設計和利用三菱FX2N可編程控制器（PLC）對自動換刀系統的控制系統進行設計。機械設計主要包括分度機構及定位機構的選擇和刀架主軸的設計等。控制部分為自動和手動換刀兩種工作方式。
關鍵詞 數控刀架，PLC控制，液壓控制

ABSTRACT
Numerical Control lathe will be developed to middle and senior grade in the future. It is estimated that the demand for NC tool carrier will be much greater. NC tool start to the rapid tool change, electrohydraulic servo driving and portfolio-driven direction with the development of NC lathes.
The paper takes electrohydraulic driving. It was discussed that mechanical design and control system design by Mitsubishi FX2N programmable logic controller (PLC) of the eight engineering automatic tool change. Machinery part includes the positioning tools and the degree of positioning choices and tool spindle design. Control part is divided into auto control and manual control.
Key words ATC，PLC control，Hydraulic control
