An active lightning protection system and method is disclosed. The device also includes a test data input buffer configured to receive test data from an external source, and control circuit that controls the non-volatile memory core and the test data input buffer. Upon completion of learning process the neural network device can generate automatically, without any intervention of the operator, merely on the basis of the CAD 2D, 2,5D or 3D part models, taken from a conventional CADCAM system, various new numerical control programs for different parts, which have not been in the machining process before. Due to the high thermal conductivity of the carbon fibers, a lower loading percentage is needed to obtain significant gains in thermal conductivity.
