Intensification Techniques for Polymer Composite Material Processing

The paper presents highly efficient manufacturing techniques for intensifying machining of polymer composite materials: high-speed machining, wide-cut method and cutting with preliminary damage to the chip. Such techniques greatly decrease process time, significantly improving labour productivity. Along with enhancing performance we considerably improve manufacturing precision and finish quality of surfaces. We achieve this by purposefully altering the energy state of the material, applying combined power effects and exploiting physical principles of the machining process taking into account the specifics of the material. In the case of cutting with preliminary damage to the chip, an increase in machining precision is ensured by using a low cutting force and correctly selecting the direction in which the additional device affecting the chip applies its pressure. In the case of wide-edge processing, a considerable increase in tool lifetime helps to improve precision, while using the main cutting edge of the tool to shape all work surfaces ensures low roughness
