US 2009/0212032 A1 · Optimized machining of a contour using a pulsed tool

Abstract

A pulsed machining method for the optimized machining of a contour which is characterized in that the instantaneous frequency ratio of φ of the pulse frequency of tool fL and of the rotational frequency of tool fCNC is optimized to achieve a highest possible degree of coverage of the individual machining pulses in the context of a shortest possible machining duration and without a direct concatenation of the machining pulses. It is especially preferred that this be achieved in that frequency ratio φ is an irrational number, thus cannot be expressed by the ratio of two whole numbers. By applying the method according to the present invention, a considerable time savings is achieved since there is no longer a need for time-consuming preliminary trials to ascertain an at least sufficient frequency ratio φ.

A method of pulsed machining of a contour of a workpiece with a beam tool, the method comprising the step of:

pulsing a beam tool and creating a movement between the beam tool and a workpiece to machine a predefined contour of the workpiece, the pulsing and the creating a movement being such that an instantaneous frequency ratio φ of a pulse frequency fL of the beam tool and a rotational frequency fCNC is adjusted in such a way that machining pulses are distributed in an optimal number of locations along the predefined contour of the workpiece, the rotational frequency fCNC being one of a rotational frequency of the beam tool with respect to the predefined workpiece contour or a rotational frequency of the predefined workpiece contour with respect to the beam tool.
