Abstract
A machining method for at least one shaping machining operation can include carrying out a machining operation over a first distance using a cutting tool which is subjected to axial oscillations as it moves forward, then reducing the amplitude of the axial oscillations while continuing to drive the cutting tool in terms of rotation.
Claims15
A machining method for at least one shaping machining operation, the method comprising:
- carrying out a machining operation over a first distance using a cutting tool which is subjected to axial oscillations as it moves forward, wherein the axial oscillations are obtained using a vibration system comprising a smooth ring and an undulating ring, then
- reducing the amplitude of the axial oscillations, while continuing to drive the cutting tool in terms of rotation,
- wherein reducing of the amplitude of the oscillations occurs via passivation of the vibration system, the passivation being obtained by a resilient damping member which absorbs all or part of vibration forces.
A machining method for at least one shaping machining operation, the method comprising:
- carrying out a machining operation over a first distance using a cutting tool which is subjected to axial oscillations as it moves forward, then
- reducing the amplitude of the axial oscillations, while continuing to drive the cutting tool in terms of rotation,
- wherein the reducing of the amplitude of the axial oscillations results from an action on a vibration system at an origin of the oscillations and the axial oscillations are obtained by rolling between two rolling surfaces, at least one of which is an undulating surface, the surfaces having, during the production of the oscillations, different rotation speeds, and wherein the reducing of the amplitude is obtained by reducing the relative rotation speed between the surfaces.
