Most Injection moulding machines use a 'Euromap" interface for robots. Been around for a while, but obviously European. I don't know what lathes or milling machines have.
My feeling is that any machine only needs a few parallel lines to signify status. The interaction is usually at a very simple level in any case. The critical part is the validity and reliability of the handshake signal. It is sometimes prudent to add additional hardware switches to doors or arms to safeguard each machine from the other as well as the operators. I would be loathe to rely on a serial interface. It's a bit like the scenario of a software versus hardware Estop. Accidents happen when people change configs, or run a different job without the right settings. However, they are very unlikely to remove a hard-wired door switch. I suppose you could have both; passing serial info and hard-wired safety interlocks.
