Thanks
I will go with it and try to do with stepper and pic

Hi Al_The_Man
I have discussed with my colig and decided we will use servo motor of 5kg torque.
Is PIC will be able to drive Servo.I have no idea on how to drive Servo.
I want to drive X and Y slides upto a resolution of minimum .1 mm.

There is many examples out there on the web, I would start with the App notoes on the PicMicro site as well as the forums.

if servo successfully works with Microcontroller IC.so what is the reason behind using PLC in all CNC Machines

[Al_The_Man]

PLC's can be used with a servo card attached, just than many are not suitable for CNC and interpolated moves.
The typical industrial CNC has co-processors, one is used to handle the Servo loop PID control and positioning ran via the part program.
The other is used as a PLC, it typically does not run in real time, so this is used for the machine control logic I/O etc.
They both communicate over a common buss with shared registers.
