谈一谈什么是"CNC"区域

Question

如题所述

Answer 1

CNC区域的话楼上说的那个就不对了。我觉得楼主问的应该是洁净区的CNC区域吧？
CNC是英文 “Controlled Not Classified”的首字母缩写，翻译成中文即“受控但未分级区域”。

参照ISPE的定义：
Controlled Not Classified (CNC)
An area without airborne particle limits, but with filtered ventilation.

更进一步的说明如下（

ISPE Baseline Guide, Vol. 3: Sterile Product Manufacturing Facilities (Second Edition)
）：
Controlled Not Classified (CNC)
A non-classified room environment where closed processes and their immediate support systems may be located. CNC space is cleanable, access controlled and served with filtered ventilation air; procedural controls and personnel garment upgrades may be applied at the Owner’s discretion. In the biopharmaceutical industry CNC is replacing the term “Gray Space”.

可以看出，CNC区域的硬件有空气处理单元，为该区域提供过滤后的洁净空气；软件方面，要求进出控制、更衣、做清洁。

与传统的洁净区相比较，就是无需设定相关的尘埃粒子限度，也不需要进行监测。但是相关的清洁和控制是需要进行的。

Answer 2

CNC是英语 computer number control的缩写，意思是电脑数字控制，也就是数控，
CNC领域用说的是数控领域的意思，多用于数控铣床、加工中心等数控加工设备中。
