CRACK DEVELOPMENT IN LINER USING CAGINALP PHASE FIELD MODEL
Journal Title: Proceedings in Manufacturing Systems - Year 2015, Vol 10, Issue 1
Abstract
New materials technologies have led to new composite materials solutions to replace existing conventional materials. The respect of the quality and the life span of drilling tools are considerable reduced. The constraints generated during the drilling process are very important in amplitude and complexity. In this scope was presented adopted machining solution based on vibration assisted drilling. This paper aims to dynamic study of a new drilling solution assisted with vibration. This system is the subject of a patent [4]. To evaluate the dynamic behaviour of the drilling vibration system an experimental protocol was designed and built. The study allowed the identification of natural frequencies and determination of dynamic parameters: stiffness, damping and mass. These parameters are required in the further development of a dynamic model to optimize the reel cutting conditions. For this purpose was imposed a dynamic evaluation of drilling system assisted with forced-vibrations.
