1. The making of a cone-shaped tread (of a wheel); the condition of being coned (see coned adj. 2).

1837 W. B. Adams Eng. Pleasure Carriages 297 The coning of the wheels must also act like a wedge... This, together with the coning of the wheels, would make a nearly perfect railway carriage.

1888 Lockwood's Dict. Mech. Engin. 85 Coning, the turning of the taper on the diameters of railway wheels and crane and turntable rollers.

1906 Times Engin. Suppl. 12 Sept. 291/2 The coning of the wheels and the slight inward cant of the rails.

2. Aeronautics. The action of the rotor blades of a helicopter slanting upwards when in motion so as to produce a cone-shaped pattern of rotation; hence coning angle: the angle at which the rotor blades rise in coning.
