Tracing control method and apparatus

摘要

A tracing control method includes the steps of (a) controlling a movement direction of a move point (P) to a tangential direction of an objective locus (C) at a present position of the move point (P) and (b) moving the move point (P) in the movement direction at a non-controlled speed. A tracing control apparatus includes (a) a direction control actuator (2) for controlling a movement direction of a move point (P) and (b) a drive actuator (3) for driving the move point (P) at a non-controlled speed. <IMAGE>
