This paper presents a novel implementation of digital twin (DT) technology in monitoring the wear condition of micro tool (TWM) during micro-milling process. The proposed DT is capable to predict the wear condition of micro tool using electric current data of spindle motor. This minimal setup of the system gives potential benefits for various deployment in real industrial practice. A miniaturized 5-axis micro-milling machine was used in the experiment to perform slot milling in micro-meter level. The proposed DT shows promising result of TCM in micro-milling within Industry 4.0 framework.
