In electrodischarge machining (EDM) material is removed thanks to phenomena connected with electrical discharges between workpiece and electrode tool (material melting and evaporation).
Such way of material removal cause, that machinability is not connected with mechanical properties of machined material, what makes EDM as an efficient method for shaping difficult-to-cut conducted materials (hardened steel, carbides, composite materials, ceramics).
In 3D-ECMM material is removed by electrode with a three dimensional movement.

Introduction An important advantage of thermoplastics is that they can be remelted, thus it is a relatively simple task to recycle these type of materials.
It seems to be reasonable to add additive materials to these fibers that increases the flame resistance.
Experimental materials SKYPET BL8050 PET copolymer was used as the raw material for the investigations.
