Abstract
A device for controlling and positioning a carriage in a tool machine, in particular the feed carriage on a gear hobbing machine. The device utilizes cams oriented one after the other and which operate a plurality of switches to control the advance of the carriage. The end position of the carriage which is controlled by a control switch is determined by two cam carriages. The first cam carriage is positionable with a rough or coarse adjustment relative to the machine frame and the second cam carriage is finely adjustable relative to the first cam carriage. The cam carriages carry the aforementioned cams to effect a control of the movement of the feed carriage path adjacent the workpiece.
