Micromilling can create complex 3D features required in Ti-alloys which find applications in biomedical implants and aerospace components. However, for difficult-to-cut materials, micromilling is usually performed at low feed rates and high spindle speeds to reduce the chip loads and the cutting forces to counter the limited stiffness of the micro-tool. Micromilling is particularly prone to dynamic instability, and if the cutting tool and the workpiece are not stiff enough to sustain the variation in the cutting forces, chatter will be induced. In this study, the effect of lubrication on chatter in high speed micromilling process has been analysed experimentally. It is expected that the tool-chip interaction will affect the dynamic stability in high-speed micromilling. Hence, the effect of lubrication on dynamic stability during micromilling of Ti-6Al-4V has been investigated in this paper. Experimental studies have been carried out using different spindle speeds, depth of cut and feed per tooth in both dry and lubricated condition. Measurement of tool displacement shows that deviation of tool from its position during machining with lubrication is significantly reduced as compared to dry machining. It has also been observed that lubrication suppresses chatter under certain machining conditions, as dry machining exhibited chatter under same conditions.
