Abstract
A device for controlling a feed motion of a feed control axis and a rotary motion of a rotary control axis, both axes being provided in a machine tool so that the rotary control axis is fed along the feed control axis. The device includes an interference estimating section estimating an interference generated between the feed control axis and the rotary control axis, based on a position command instructed to at least one of the feed control axis and the rotary control axis and a position and mass information of an eccentric load carried by the rotary control axis; and a command correcting section correcting a current command given to at least one of the feed control axis and the rotary control axis, based on the interference estimated by the interference estimating section.
