RE: [CAD_CAM_EDM_DRO] CNC Controler Software

Paul,

I realize that a RTOS or dedicated signal generator can produce stable pulse rates, but what I don't grasp is what is the result. That is to say, if I first machine a part using a CNC controller running under windows with no signal generator, and then secondly machine that same part using a CNC controller running under a RTOS or using a real-time signal generator, what will be the difference in the two parts?

My initial thinking would be that the first part would be getting the exact same signals as the second part, just not with a consistant time interval between each signal. I understand complexity of the part dictates plenty, but I'd like to have my machine capable of a range of complexity.

-Archie

Hi Archie

General purpose operating systems suck at producing stable pulse rates at
high speed - Microsoft Windows is probably one of the worst offenders and can
not be relied on under load (aside from all the security bugs). DOS can be fairly dependable, but it just isn't capable of doing
multitasking. Linux can do fast pulse generation, but it does have it's
limits.

It really depends on how fast you need the step pulses, and how dependable
the underlying Operating System is.

Regards, Paul.
