Abstract

This paper investigates the influence of various parameters on the precision of the conductivity-based touch-off method for micromilling. A preliminary explanation of conductivity-based touch-off mechanics for micromilling is proposed as a prediction of the relationships between parameters choices and resulting high precision. The conductivity-based touch-off method has the advantage of being low-cost and simple to implement. In this study, various combinations of process variables were tested on the touch-off and the precision of the touch-off was measured. An analysis of variance was performed to determine the magnitude of the effect of each variable. It is found that touch-off precision within 1μm can be achieved with this method, provided that process variables are properly set.
