Based on the application of elliptical vibration cutting method to precision machining of hard and brittle materials and material softening technology through laser heating, a novel composite cutting technique, laser heating and ultrasonic elliptical vibration assisted cutting, is applied to process sintered tungsten carbide.
Ultrasonic elliptical vibration cutting (UEVC) method has been proved to be successfully applied to processing of such intractable materials [2] and have achieved much improved cutting performances in all aspects superior to common cutting (CC) and one-dimensional ultrasonic vibration cutting(1D UVC) methods due to intermittency and friction reversal actions in each cycle of vibration [3-5].

In many practical applications of induction heating of paramagnetic materials, when power supplies have appreciably limited frequency adjustability (), the heat source distribution along the length or the radius of billet has fixed dependence.
Conclusion This paper demonstrates the possibility of analytical identification of the constant value of internal heat source power during the induction heating processes of paramagnetic materials from the measured temperature.

It is considered that non-degradable materials are solely responsible for environmental pollution.
Nowadays, different non-degradable composite materials are widely used instead of metals.
Non-degradable materials are subjected to be replaced by degradable one in order to make pollution-free environment.
Thus, natural fiber composites are chosen up to make biodegradable materials [1-2].
