Abstract: Deep hole drilling is a machining process with a high ratio of length to diameter (L / D). If the depth is greater than the diameter, vibration frequently occurs at the end portion of the cutting tool resulting in a product with defective hole surface and size. To solve this problem, dampened bars are installed to absorb vibration. Depending on their length, the dampened bars can lower process efficiency. Instead, a mill turret developed with a holder and sleeve could enhance quality and improve productivity while reducing vibration. In this study, an optimized model of a mill turret holder and sleeve was developed to reduce vibration and replace the dampened bar. To optimize the design parameters, a Design of Experiment (DOE) was used. A finite element analysis was performed using ANSYS. Using Modal analysis and Harmonic analysis, the control factors affecting stress and displacement were examined using a derived signal to noise (S/N) ratio.
