Module for detecting contact between object to be processed and precision tool tip and method for detecting contact using same

A contact detection module for detecting whether a precision tool tip and an object to be processed are in contact with each other in a lathe in which the object to be processed is cut using the precision tool tip, the contact detection module comprising:

• a first conductive layer applied to an area of the precision tool tip, which performs processing while being at least in contact with the object to be processed;
• a conductive unit comprising a first conductive line connected to the object to be processed, through which an electric signal flows, and a second conductive line connected to the first conductive layer, through which the electric signal flows;
• and
• a detection unit comprising a signal generation unit configured to supply the electric signal to at least one of the first conductive line and the second conductive line and a detection unit provided in the conductive unit to detect whether the electric signal flows through the entire conductive unit, and configured to determine whether the object to be processed and the precision tool tip are in contact with each other, based on a change in the electric signal detected by the detection unit.
