Machining of materials assisted by induction heating, in particular chip forming machining of titanium alloys or materials with similar low thermal conductivity

摘要

The method involves heating a portion of a workpiece to be machined by electromagnetic induction by a suspension of parts of the workpiece of a changing magnetic field to produce eddy currents in a part of the workpiece. The heated portion of the workpiece is directly machined, where heating is caused by relative movement of an inductor at a small distance to the surface to be heated portion of the workpiece. A relative movement of an inductor is regulated, where the workpiece is made of titanium alloy or a material with lower thermal conductivity. An independent claim is also included for a device for machining a workpiece, comprising a holding unit.
