摘 要
數(shù)控車床又稱數(shù)字控制（Numbercal control，簡稱NC）機床。它是基于數(shù)字控制的，采用了數(shù)控技術(shù)，是一個裝有程序控制系統(tǒng)的機床。它是由主機，CNC，驅(qū)動裝置，數(shù)控機床的輔助裝置，編程機及其他一些附屬設(shè)備所組成。
本次設(shè)計課題是CK6140數(shù)控臥室車床，CK是數(shù)控車床，61是臥式車床，40是床身上最大工件回轉(zhuǎn)直徑為400mm。
此次設(shè)計包括機床的總體布局設(shè)計，縱向進給設(shè)計，其中還包括齒輪模數(shù)計算及校核，主軸剛度的校核等?？刂葡到y(tǒng)部分包括步進電機的選用及硬件電路設(shè)計和軟件系統(tǒng)設(shè)計，說明了芯片的擴展，鍵盤顯示接口的設(shè)計等等。

Abstract
The numerical control lathe called the numerical control (Numbercal control, is called NC) the engine bed. It is based on the numerical control, has used the numerical control technology, is loaded with the procedure control system the engine bed. It is by the main engine, CNC, the drive, the numerical control engine bed auxiliary unit, the programming machine and other some appurtenances is composed.
This design topic is the CK6140 numerical control bedroom lathe, CK is the numerical control lathe, 61 is the horizontal lathe, 40 is on the lathe bed the biggest work piece rotation diameter is 400mm.
This design including the engine bed overall layout design, longitudinal enters for the design, also includes the gear modulus computation and the examination, the main axle rigidity examination and so on. The control system partially including step-by-steps the electrical machinery to select and the hardware circuit design and the software system design, explained the chip expansion, keyboard demonstration connection design and so on.
