Abstract
The new approach to high-performance turning of polymeric composite materials is presented in this paper. The approach essence is a combination of a conventional work pieces turning with simultaneous irradiation by nanosecond electromagnetic pulses. As a result the changes of studied material structure occur that lead to technological softening the work pieces surface layer. It has been experimentally proved that irradiation of the studied materials with nanosecond electromagnetic pulses for 5 and 10 minutes leads to a noticeable decrease in the strength and hardness of all samples. On the basis of the experimental data the new turning methods for polymer composite materials and the device for its implementation have been developed and patented. Analysis of the experimental studies data allows us to conclude that such approach leads to decreasing in cutting force during work pieces subsequent turning and, therefore to increasing in the process productivity, for example, due to increasing cutting speed or size of the removed allowance.
