New Technologies for Surface Layer Quality Improvement in Cutting Fibrous Polymer Composite Materials

The paper shows that an effective method to improve the quality of machining the products made of fibrous polymer composite materials can be application of technologies based on additional thermo-mechanical effect, which provides the desired treatment result by changing the state and properties of the material of the surface layer of the workpiece. By test we established the rational temperature values and the duration of its impact on the processed surface of the workpiece. Findings of the research show that under optimal conditions of thermo-mechanical treatment it is possible to achieve a significant reduction in roughness of the processed surface, and hair formation is completely eliminated. The effectiveness of the new technology was verified experimentally when processing internal and external cylindrical surfaces
