What is ISO 21919-2 about?
ISO 21919-2 deals with the safety interface and control interface. ISO 21919-2 allocates signals to a conformance class and conformance option. ISO 21919-2 describes the detailed functions of each signal, describes and displays the timing interactions between signals in flow charts and shows examples for safety matrices and safety-related functional relationships.
ISO 21919-2 defines 3 conformance classes and dedicated conformance options. Classes and options consist of a number of signals to:
- Allow a flexible adaptation of the interface to a project-specific scope of functions
- Tie sets of signals tight enough to avoid unnecessary coordination efforts between suppliers of the machine tending systems and machines
Who is ISO 21919-2 for?
ISO 21919-2 on automated machine tending is applicable to:
- Designers of machine tending systems
- Manufacturers of machine tending robots
- Manufacturers, dealers, and suppliers of CNC machines
- Services involved in safety and inspection of CNC machinery
Why should you use ISO 21919-2?
Automated machine tending is the integration of a robot into a machine tending application for the purpose of loading and unloading the machine tool without the intervention of any operators.
ISO 21919-2 gives you guidelines about interfaces for automated machine tending of computer numerically controlled (CNC) machine by using machine tending systems, that are easy to follow. ISO 21919-2 provides you with a description interface that includes conformance class, conformance options and safety interface in addition to principle approach, matrix for safety relationships, PFHD value, that helps you enhance the safety and performance of your CNC machines.
