Structure of an NC program

In most cases, NC code follows a clear structure, especially when it was generated by CAM software. Depending on the section, the program contains different information and instructions: from the program header through tool calls to the actual machining blocks.

The following graphic shows what such a structure looks like:

On machines where a rotary/tilt table has been retrofitted, the control often provides no tilt cycle such as G68.2 or PLANE SPATIAL. This means that for every tilted position, a zero point has to be probed manually and entered into the offset table. The procedure is cumbersome and error-prone: setup time and scrap rates increase because a correction, at a compound angle for example, can only be made after machining.
