METHOD AND DEVICE FOR WIRE CUTTING OF A MATERIAL

摘要

The invention relates to a method for wire cutting of a material, wherein a cutting wire is advanced into the material by causing said wire to scroll in such a way as to progressively cut the material, the method being characterised in that it comprises: the measurement of a force applied by the wire on the material as a function of time, the measurement of the advancement of the wire in the material as a function of time, the determination, as a function of said force and said advancement of the wire, of a variable characterising the state of the wire cutting and, servo control of at least one cutting parameter through changes in said variable so as to reduce the rate of wear of the wire and/or to reduce the risk of breaking of the wire. The invention also relates to a device for wire cutting allowing implementation of said method.
