This research deals with a method of friction control for a linear guideway, which is based on ultrasonic oscillations. Experiments were conducted by driving a single-axis guideway in sinusoidal motion as a simulation to a circular motion. The sinusoidal motion was controlled with the installation of a PI controller. The ultrasonic oscillations were applied at the guideway's carriage with 6 different oscillation patterns. Subsequently, their influence for the frictional characteristics was investigated. The investigation is focused at the inverting moving direction, when the carriage starts from zero velocity. It is observed that when the carriage was oscillated with a gradually increasing intensity, the static frictional force and the maximum displacement error had been reduced approximately by 39% and 29%, respectively.
