GB/T 8870.1-2012 in English

《GB/T 8870.1-2012自动化系统与集成 机床数值控制 程序格式和地址字定义 第1部分：点位、直线运动和轮廓控制系统的数据格式》由TC159（全国自动化系统与集成标准化技术委员会）归口，TC159SC1（全国自动化系统与集成标准化技术委员会物理设备控制分会）执行，主管部门为中国机械工业联合会。

Scope

This part of GB/T 8870 puts forward requirements and suggestions for the data format of the point position, linear motion and contour control system used in the numerical control of machine tools, which is helpful for coordinating the system design and minimizing the types of programs required by the part processing drawing. In this way, the unification of programming technology is promoted, and the input program is interchangeable among CNC machine tools of the same classification such as model, processing technology, function, size and precision. It is hoped that a simple format will be used for the programming of purely numerically controlled machines, and only a step-by-step extension of the system for more complex machines. This section does not apply to the numerical control of flame cutting machines and plotters dedicated to the shipbuilding industry. Their associated format ("ESSI format") is specified in ISO 6852.
