Is a program that resides in a CNC considered an embedded device?

Is a motherboard in a CNC considered an embedded device? (Do they have motherboards?)

Would the memory contained in the CNC be considered an embedded device?

Is there a certain amount of ram required by a CNC? (I know, open question!)

Is a hard drive in a CNC considered an embedded device?

If so, are they devices/systems that would fall under a document/data control requirement or a 4.9 process control requirement?

How do you control the programs? 1.4 Floppy? Networked?

Are there lockout keys for CNC programs included in the Document/Data control system?

I think I know the answers but would like to generate some discussion!!!!

Some fella sent me numerous e-mails requesting this forum,. and now he doesn't even post or visit - or so it appears. Just like the guy crying for a book review forum...

However - I take embedded devices to be the hardware. Their software is technically firmware, I believe - which is no less than software.

A motherboard contains many devices, typically, however usually when we talk about embedded devices we are talking about a 'blackbox' component of assembly.

A CNC is not really what the forum is about, but a CNC has a compiler (firmware) 'built in', as I understand it. You program the CNC and the firmware translates the program you input. Older CNCs used, at one time, data tapes.

I don't think you can generalize about things like memory needs. heck - CNCs come in all sizes, shapes and complexity. The components of the CNC are not typically called embedded devices.

Firmware is controlled by the CNC maufacturer but installation is another issue. You may do a firmware upgrade but more often a representative of the CNC manufacturer does this, if necessary, at calibration time.

The program you control - just like you would a procedure. Most controllers have a password or other lock-out mechanism built in.
