Influence of cutting parameters on vibrations in trimming of a Glass Fiber Reinforced Polymer Composite plate
Résumé
Many parameters -such as tool geometry, composite constitution, cutting parameters, lubrication- have an influence on milling of composites. These parameters may affect cutting forces, vibrations and tools wear and consequently tool lifetime and quality of the composite. In this paper, we focus on the influence of three cutting parameters (cutting speed, feed per tooth and radial engagement) on vibrations during the trimming of a Glass Fiber Reinforced Polymer plate. For five different values of these three parameters we record the acceleration with an accelerometer and calculate the Root Mean Square value of acceleration. The experiments show that the most influent parameter is the cutting speed Vc: the RMS value of acceleration increases with Vc. Varying the radial engagement gives similar trends except that the RMS reaches a threshold for high levels of radial engagement. The feed per tooth variations does not affect significantly RMS value of acceleration, maybe due to the small range of variation of the feed per tooth.
