16刀刀库是在小型加工中心应用最为广泛，根据使用的场合和实际运用的要求，设计了相应的16刀的圆盘式刀库，并且对它的控制进行了一定的研究

ABSTRACT
Tool storage is one of the main components of the automatically-trading-knife installment. Its capacity, position and structure have great influence to the design of the machining centre.
16-tool tool storage is widely used in the machining centre. Based on the situation and requirement the 16-tool used, the disc-style tool storage of the 16-tool is designed and some research about its control is made in this paper.
The paper illustrates the design project of the 16-tool tool storage firstly, and then explains its operation principle, and at last calculates and designs the structure and control of the tool storage separately by chapters.
The design of the structure of the tool storage is the key point of this research. Driving part is a decelerating set of the worm and worm gear. The sizes of the worm, worm gear and axis are calculated. The control parts are tool storage delivering parts, which is completed by the hydraulic pressure and PLC control.
Key words: machining centre, tool storage, worm, worm gear, hydraulic pressure, PLC
