本标准旨在作为协调系统设计的指南，最大限度地减少所需程序手稿的多样性，促进编程技术的一致性，并促进按类型、过程功能、尺寸和精度划分的相同类别数控机器之间输入数据的互换性。其目的是使用简单的格式对简单的数控机床进行编程，该格式可系统地扩展到更复杂的机床。

This standard is intended to serve as a guidein the coordination of system design, to minimize the variety of program manuscripts required, to promote uniformity of programming techniques, and to foster interchangeability of input data between numerically controlled machines of the same classification by type, process function, size, and accuracy. It is intended that simple numerically controlled machines be programmed usinga simple format, which is systematically expandable for morec omplex machines.
