Difference between programmed path and actual travelling path- how to solve ?

When i use G0 ,fast travelling speed , machine don't travel to the end of programmed path .
How to solve this problem ?

This can be danger to crash with tool into peace and damage maschine.

Assuming you are using step motors you need to figure out why they are loosing steps and there are lots of possible reasons. Is it because of too high acceleration, too high max velocity, marginal step space timing settings, poor control signal (3.3v parallel port connected to a drive that needs a 5v signal), electrical noise, or other wiring problems.

They don't lose steps.
I had used TurboCNC and i hadn't had this problem with it.

I have changed cycle time =0,10. Better results but still not perfect.

If your scaling is right for lower speed moves but your coming up short on rapids, That is the definition of loosing steps. (and seemed to be what you were implying from your original post.)
Steps can be lost in other places besides between the motor and step driver. The motor might not be missing any of the steps it is commanded to by the driver, but perhaps the driver isn't getting all of the steps that Linuxcnc is commanding. The most likely causes of this are either step space or step hold time is too short, or a wiring/port voltage problem causing marginal signal quality (slow steps get through but fast ones don't always make it because of voltage rise times).

One thing to remember steps are not on/off for equal times for any given velocity. They are turned on for the step hold time then off for the remainder of time. Therefore unless you need really fast steps there is no advantage to specifying a very short step hold time.
