Downhole tool for automatic tubular cutting

A method for cutting tubing in a wellbore, comprising:

• causing anchor arms of an anchor module to extend outward to an inner wall of tubing;
• rotating a cutting head with an orientation coincident to an axis of the tubing, wherein the cutting head includes a plurality of cutting elements, wherein the anchor module is positioned above the cutting head instead the wellbore;
• forcing the cutting elements outward using an actuation mechanism to form a cut in the tubing, wherein the actuation mechanism is connected to a pressurized piston disposed within a piston housing, wherein the cutting elements gradually expand radially as material of the tubing is cut away;
• determining a depth of the cut made by the cutting elements based upon pressure pulses, wherein the pressurized piston includes a radially protruding detent and an inner surface of the piston housing includes an actuation profile including one or more ridges, and wherein the pressure pulses are generated by the detent overcoming the one or more ridges;
• and
• adjusting hydraulic pressure to the cutting head based on torque feedback of the cutting elements.
