Patent number: 5184053Abstract: A control device for a tool driving unit is disclosed wherein a tool such as a tap or a drill is controlled to be rotated and axially moved by the control device. The tool driving unit has a spindle servo motor adapted to be driven according to a spindle current command and a feed shaft servo motor adapted to be driven according to a feed shaft current command which are provided by a single microcomputer which operates as the control device. The microcomputer reads an NC program and outputs a spindle command for the spindle servo motor when performing tapping, and outputs both the spindle command and a first feed shaft command for the feed shaft servo motor when performing drilling. A thread pitch changing controller for controlling a thread pitch outputs a second feed shaft command for the feed shaft servo motor when performing tapping.Type: GrantFiled: April 2, 1991Date of Patent: February 2, 1993Assignee: Brother Kogyo Kabushiki KaishaInventors: Satoshi Maruo, Chikamasa Hattori, Fumio Kameyama
