Acceleration and deceleration control apparatus and method thereof

Abstract

An acceleration/deceleration control apparatus for a computer numerical control machine tool includes an interpolator, a motion-transforming unit, and a drive transforming unit. The interpolator receives a velocity signal and outputs a pulse velocity signal. The motion unit is connected to the interpolator and includes an operation filter. The operation filter includes a plurality of different weight values and a plurality of registers corresponding to the numbers of the weights to calculate the pulse velocity signal to an acceleration/deceleration pulse velocity signal by a first function. The weight values are derived by a second function corresponding to the shape of the acceleration/deceleration pulse velocity signal. The driving unit is connected to the motion unit and transforms the acceleration/deceleration pulse velocity signal to a driving signal to drive a motor.
