CNC systems software and hardware components,The hardware for the operation of the software support environment.CNC systems real-time requirements The highest task is interpolation and position control,That is, in a sampling period Must complete the calculation of the control strategy,But also leave some time To do other things.CNC interpolation Both for software and hardware-oriented. To sum up, there are three main types:
(1) do not have the software interpolation,Interpolation is completely CNC system hardware.
(2) by software interpolation to complete the coarse interpolation,Completion of the the fine interpolation CNC system by hardware interpolation
(3) CNC systems with entirely software implementation of the interpolator.
