摘要: Abstract The complexity and increasing demand of turbomachinery components manufactured for the aerospace sector has led these parts to become reference research development 5-axis machining. We can highlight as key Integral Bladed Rotors (IBR), such impeller blisk. Due its functional technical requirements, are formed by complex geometry in difficult cut materials. Despite recent advances five-axis machining, reliable efficient manufacturing is still a challenge. Conventional pure geometric analyses carried out CAM systems insufficient machining process with high mechanical stresses. Tool deflections and/or vibrations finish operations produce damages piece or components. In present work cutting force model barrel-shaped cutter proposed order optimize toolpath design process.
