一、概述 1.经济型数控的特点 由于微型子技术的迅速发展,全功能微机数控系统的功能越来越丰富,但价格较贵,而且在某些具体的场合,其功能不能充分应用。为了能较多的降低产品价格,又具有适用的功能,便出现了适应不同范围的、简化功能的经济型数控系统和数控机床,人们习惯称为简 First, an overview 1. The characteristics of economic NC Due to the rapid development of micro sub-technology, full-featured microcomputer numerical control system more and more rich, but the price is more expensive, and in some specific situations, its function can not be fully applied. In order to more reduce the price of the product, but also has the applicable function, has appeared to adapt to different scopes, the simplified function economical numerical control system and the numerical control lathe, what people used to call Jane
