Abstract
Machining of polymeric materials using laser techniques results in poor dimensional accuracy and machined surface quality. However, laser processing has substantial favorable effects such as high material removal rate. This paper presents an investigation into the existing challenges, possible solutions and strategies for carrying out experimental research on polymer materials. It is evident that The laser source and fundamental wavelength plays an important role in controlling the energy for the material removal action. Speed and laser power are the two key parameters for controlling the quality of machined surfaces. Two-pass method is a novel strategy to improve dimensional accuracy of features. The application of low frequency vibrations in the range 12–24 Hz improves laser machining speed.
