Features of CNC control
CNC的控制特点

In previous the important features and functions of the machine control unit in numerical control were described.
在前面对数控机床控制单元的重要特征和功能进行了描述。
CNC has made possible additional features beyond what is normally found in a conventional hard-wired MCU. Some of these features include the following:
数控已经超出了通常在传统的硬连线的单片机中可能发现的附加功能。其中一些功能包括以下内容?
1) Storage of more than one part program.
存储多个零件程序
With improvements in computer technology, many of the newer CNC controllers have a large enough capacity to store more than a single program.
随着计算机技术的改进,许多新的CNC控制器有一个足够大的容量来存储大于一个单一的程序。
This translates into the capability to store either one very large program or several small and medium-sized programs.
这能力意味着存储成功其中一个非常大的程序或几个小型和中型项目。
2) Use of diskettes.
使用软盘
There is a growing use of floppy disks for part programs in manufacturing. The capacity of an 8-in.
有越来越多的软盘制造业中的部分程序使用8合一的能力。
Diskette is the approximate equivalent of 8,000 ft of punched tape. Because of this more modern storage technology, many CNC controllers have the optional capability to read in programs stored on disks as well as punched tape.
软盘是大致相当于8000英尺纸带。因为这更现代的存储技术,许多CNC控制器可选的阅读能力在磁盘上以及纸带存储方案。
3) Program editing at the machine tool site.机床网站编辑计划 To deal with the mistakes in part programming, CNC systems permit the program to be edited while it is in computer memory.
为了解决部分编程的错误,数控系统允许程序编辑,而它是在计算机内存中。
Hence, the process of testing and correcting the program can be done entirely at the machine site rather than returning to the programming office in the shop to make the tape corrections.
因此,完全可以在机器网站中测试和纠正计划的过程,而不是去店里的编程办公室进行磁带更正
In addition to part program corrections, editing can also be done to optimize the cutting conditions of the machining cycle.
除了部分程序更正,编辑也可以进行对切削条件下加工周期的优化。
After correcting and optimizing the program, a tape punch can be connected to the CNC controller in order to obtain a revised version of the tape for future use.
纠正和优化方案后,纸带穿孔机可以连接到CNC控制器,以获得供将来使用的磁带的修订版本。
