Abstract

In order to smooth the movement of a machine, the acceleration and deceleration for the movement of the machine axes should be controlled. For CNC systems, two kinds of Acceleration and Deceleration (Acc/Dec) control methods have been developed; Acc/Dec Control Before Interpolation (ADCBI) and Acc/Dec Control After Interpolation (ADCAI). These are classified based on the order in which the Acc/Dec control is executed. In this chapter, first we will introduce the Acc/Dec control after interpolation that was originally used for NC systems. Following this, we will introduce the Acc/Dec control before interpolation which is suitable for high-speed and highaccuracy machining. In addition, a Look Ahead Algorithm will be addressed that is used with the Acc/Dec control before interpolation for Die and Mold machining.
