In case of vibration, reduce RPM and feed rate by the same ratio. Aluminum machining Built-up edge Low heat resistance could create residual stress or inaccuracy after machining. Scratch due to low hardness Low tool life due to flank wear Trouble shooting for Aluminum machining Use a higher rake, sharp edge and oil (MQL) mist to decrease cutting load and built-up edge. Increase Vc and reduce the depth of cut for better surface finish. 1 Endmills 81
