Abstract:
A numerical control device for a turning mechanism that turns a body about a shaft and is driven by a driving source that includes an output that moves in a non-circular motion and turns said body via a non-linear transmitting mechanism, said numerical control device comprising:a coordinate transformation device for outputting a signal obtained by converting a signal corresponding to an angular position of said body about said shaft while being driven by said transmitting mechanism into a position of said output of said driving source; anda compensator for outputting a signal obtained by computing a compensation value of said position of said output of said driving source in accordance with said signal corresponding to an angular position of said body about said shaft while being driven by said transmitting mechanism,the signal outputted from said coordinate transformation device and the signal outputted from said compensator being added together to form a servo-input signal to control said driving source.
