Abstract: To adding the control method reducing the speed, in CNC, the population
having wielded go along in numerical control system introduces that. The population
structure adding the method numerical control system reducing the speed has carried
out the part introducing , including hardware and the software on development four
time of displacement curves. Have been used for and then explanation to the method
applying concretely in adding the system reducing the speed in , have been in progress
and by adding the method reducing the speed one processes an example , face to face
common several kind verifying and comparing.
Keywords: Add the control method reducing the speed Four time of displacement
