摘要： An apparatus for angularly positioning a rotary member such as turn table, etc. by employing two separate motors.First motor is connected to drive the rotary member in a work operation and second servo motor is connected to drive the rotary member in a servo angular positioning movement.A power transmission mechanism is connected with the first motor to rotate the rotary member in the work operation and a coupling mechanism including a single position clutch therein is connected with the second motor to rotate the rotary member in the servo movement. A first detector is provided to detect a predetermined angular reference position of the single position clutch and a second detector is disposed to detect a predetermined reference position of the rotary member and thereby allowing the single position clutch to engage. A controller is connected with the second motor and with the first and second detectors to regulate the servo operation.

摘要： A method of working on a sloping surface of work is disclosed by means of a numerically controlled machine tool comprising a cutting tool carried by a spindle movable along three orthogonal axes, and a worktable rotatable both about its own axis and about another axis angularly displaced 45 degrees therefrom. The tool movements along the three axes and the worktable revolutions about the two axes are all controlled by a numerical control system, to which there are input prescribed data concerning the particular workpiece to be machined. The numerical control system is programmed to cause the machine tool to work, for example, on a conical surface or to drill one, two or more holes in preassigned positions on a sloping surface.
