Abstract
A positive feed tool may include a motor, a gear head and a spindle. The gear head may be operably coupled to the motor and may include a drive assembly and a feed assembly. The spindle may be operably coupled to the gear head and may be selectively driven rotationally and fed axially based on operation of the drive assembly and the feed assembly, respectively. The feed assembly may include a feed rate oscillator having a fixed cam and a movable cam operably coupled to each other via a plurality of rolling elements to oscillate between a maximum width and a minimum width of the feed rate oscillator based on a position of the movable cam. The rolling elements alternate between a first state in which at least some of the rolling elements are unloaded and a second state in which all of the rolling elements are loaded.
