Feed amount setting device for a machine tool
 A feed amount setting device for a machine tool is provided wherein a cradle member, urged for contact engagement with a plate cam, is pivoted within a plane including the rotational axis of the plate cam when the same is rotated by a tool slide feed device. The pivotal movement of the cradle member is converted into the axial movement of a slide sleeve and an actuation sleeve, which is threadedly inserted into the slide sleeve for adjustment of the relative position thereto, in a direction parallel to the rotational axis of the plate cam. The actuation sleeve is formed at its one end with a radially extended flange contacting a lever arm and, when axially moved, pivotally moves the lever arm to thereby actuate a switch element. This element, when actuated, controls the operation of the tool slide feed device.
