【正文】 indle, exchange, the new knife into the spindle, the old knife back into the knife. ATC, as thenly a spindle, spindle ponents to high stiffness to meet the machining requirements. The number of establishments in larger knife, which can meet the more plex parts of the machining processes, significantly improving productivity. Daidao system for the automatic tool change applied to drilling centres and CNC machining centers. The parison drawn Daidao automatic tool change system is the most promising. Conclusion Focused on in today39。 rotary ATC devices, as shown in Figure ATC instructions received, the machine control system put ATC spindle control to the designated location at the same time, the tool movement to the appropriate location, ATC, with the rotary axis and at the sa. When the ATC mand is called, the transfercutter knives will be removed, the machine go forward, and positioning with the ATC, in line with the position. 180 186。 武漢工業(yè)學(xué)院 畢業(yè)設(shè)計(jì)（論文）外文參考文獻(xiàn)譯文本 2021 屆 譯文出處 of automatic tool changer for CNC ,Mechanical EngineeringDepartmet, METU, Ankara, Turkey 1995 畢業(yè)設(shè)計(jì) (論文 )題目 BT4024 型斗豎式刀庫(kù)研究與設(shè) 計(jì) 院（系） 機(jī)械工程學(xué)院 專業(yè)名稱 機(jī)械設(shè)計(jì)制造 及其自動(dòng)化 學(xué)生姓名 xxxxxxxxx 學(xué)生學(xué)號(hào) 090309815 指導(dǎo)教師 劉 海 岷 譯文 出處： of automatic tool changer for CNC ,Mechanical EngineeringDepartmet, METU, Ankara, Turkey 1995 翻譯 文獻(xiàn)： Time between failures model and failure analysis of CNC system [J]． .Joumal 2021， 14(2)：197201L 文獻(xiàn)作者： ZHANG H B， JIA Y Z， ZHOU G W． 英語(yǔ)原文： The original knife machine control procedures are designed individually, not used tool management system, features a single parison, the knife only has to fin the tool knife, knife positioning the shortest path, axis tool change, but does not support largescale tool. Automatic knife in the knife election, in the puter memory knifeelection on the basis of using the Siemens 840 D features, and the election procedures knife more concise, and plete the space Daotao View. ATC use the knife rapid pletion of STEP7 programming, and have been tested in practice. In the positioning of the knife, PLC controlled modular design method, which future production of similar machines will be very beneficial, it is easy to use its other machine. Automatic tool change systems will be faster growth, reduced tool change time, increase the positioning accuracy tool is an important means to help NC technology development. Tool and inventory ponents of modern production is an important link in the management, especially for large workshop D features, and the election procedures knife more concise, and plete the space Daotao View. ATC use the knife rapid pletion of STEP7 programming, and have been tested in practice. In the positioning of the knife, PLC controlled modular design method, which future production of similar machines will be very beneficial, it is easy to use its oth management. The traditional way of account management, and low efficiency, high error rate, and not sharing information and data, tools and the use of state can not track the life cycle, are unable to meet the current information management needs. With actual production, we have to establish a workshop tool for the threedimensional tool storage system to meet the knife workshop with auxiliary storage and management needs. The system uses optimization technology, a large number of puter storage inventory information, timely, accurate, and prehensive tool to reflect the inventory situation. The entire system uses a graphical interface, manmachine dialogue tips from the Chinese menu, select various functions can be realized and the importation of all kinds of information. Management system using online help function. Through the workshop management, work management and sharing of information. Have automated inventory management, warehousing management tool, a tool for the management and statistical functions. ponents and control structure The entire system, including the structure and electrical machinery control systems. structure and
