机床刀具设计(中文5300字,英文3500字)
课题研究意义
机床原来的刀库控制程序是单独设计的,没有采用刀具管理系统,功能也比较单一,只实现了刀库刀具的找刀、刀库最短路径定位、主轴换刀,而且不支持大型刀具。
在刀库自动选刀方面,在计算机记忆式选刀的基础上采用了西门子840D特色功能,使选刀程序更简洁,并完成空刀套的查找。刀库快速换刀利用STEP-7完成编程,并在实际中得到验证。在刀库定位问题上,PLC程序控制采用模块化设计方法,这对今后生产类似机床将十分有利,很容易将其利用到其他机床上。自动换刀系统将以较快的速度增长,缩短换刀时间,提高刀具的定位精度是重要的手段,有利于数控技术的发展。
刀具及其元件库存是现代生产管理中的重要环节, 特别是大型车间管理。传统的人工记帐管理方式, 效率低下, 错误率高, 且信息数据不能共享, 刀具的使用状态和寿命周期无法跟踪, 不能适应当前信息化管理需要。结合生产实际, 我们在车间刀具准备间建立刀具贮存立体库系统, 以满足车间刀辅具储存与管理的需要。
该系统采用最优化技术, 利用计算机存储的大量库存信息, 能及时、准确、全面地反映刀具库的库存情况。整个系统采用图形界面, 人机对话由中文菜单提示, 可实现各种功能选择和各种信息的输入。管理系统采用在线帮助功能。可通过车间管理层、网络系统实现信息管理和共享。具有自动库存管理、刀具入库管理、刀具出库管理和统计查询功能。

Design Of Tool Machine Prop
Research significance
The original knife machine control procedures are designed individually, not used tool management system, features a single comparison, the knife only has to find the tool knife, knife positioning the shortest path, axis tool change, but does not support large-scale tool.
    Automatic knife in the knife election, in the computer memory knife-election on the basis of using the Siemens 840 D features, and the election procedures knife more concise, and complete the space Daotao View. ATC use the knife rapid completion of STEP-7 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 components of modern production is an important link in the management, especially for large workshop 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 three-dimensional tool storage system to meet the knife workshop with auxiliary storage and management needs.
   The system uses optimization technology, a large number of computer storage inventory information, timely, accurate, and comprehensive tool to reflect the inventory situation. The entire system uses a graphical interface, man-machine 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, network management and sharing of information. Have automated inventory management, warehousing management tool, a tool for the management and statistical functions.
