This International Standard defines a file structure format

and a language format for the representation of CLDATA

on physical media.

The CLDATA reference language (RL) is used for the

machining of parts. It provides for the control of technological

functions and movement at the numerical control machine.

Each processor using one of the numerical control programming

languages shall be capable of producing

CLDATA as defined in this International Standard.

Each post processor shall be capable of using the

CLDATA defined in this International Standard as input.

The RL has been developed primarily for numerically

controlled machine tools.
