Abstract: A contact detection module includes a first conductive layer applied to an area of a precision tool tip that processes an object when in contact therewith. A conductive unit of the module includes a first conductive line connected to the object, through which an electric signal flows, and a second conductive line connected to the first conductive layer, through which the electric signal flows. A detection unit of the module includes a signal generation unit to supply the electric signal to at least one of the first and second conductive lines. A detection unit in the conductive unit detects whether the electric signal flows through the entire conductive unit, and determines whether the object and the precision tool tip are in contact with each other, in the lathe wherein the object is cut, based on a change in the electric signal detected.
