Abstract: One embodiment of the present invention can be characterized as a method for controlling a multi-axis machine tool that includes obtaining a preliminary rotary actuator command (wherein the rotary actuator command has frequency content exceeding a bandwidth of a rotary actuator), generating a processed rotary actuator command based, at least in part, on the preliminary rotary actuator command, the processed rotary actuator command having frequency content within a bandwidth of the rotary actuator and generating a first linear actuator command and a second linear actuator command based, at least in part, on the processed rotary actuator command. The processed rotary actuator command can be output to the rotary actuator, the first linear actuator command can be output to a first linear actuator and the second linear actuator command can be output to a second linear actuator.

Abstract: The invention is a method and an apparatus for marking an article and the article thus marked. It includes providing the article. Generating a plurality of groups of laser pulses. At least one of the plurality of groups is generated by modulating a beam of laser pulses to form a plurality of beamlets. Each, of the plurality of beamlets, include at least one laser pulse. It also includes directing the plurality of groups of laser pulses onto the article such that laser pulses within the at least one of the plurality of groups impinge upon the article at spot areas that do not overlap one another, wherein laser pulses within the plurality of groups are configured to produce a visible mark on the article.
