Downhole cutting tool positioning assemblies and methods to cut a tubular

A downhole cutting tool positioning assembly, comprising:

• a drive screw;
• a drive nut coupled to the drive screw and configured to shift from a first drive nut position to a second drive nut position as the drive screw rotates in a first drive screw direction;
• a pressure piston configured to shift from a first pressure piston position to a second pressure piston position in response to force applied to the pressure piston;
• a chamber comprising a fluid that is pressurized by the pressure piston as the pressure piston shifts from the first pressure piston position towards the second pressure piston position;
• a sleeve configured to slide from a first sleeve position towards a second sleeve position in response to pressure from the fluid;
• and
• a latch key having a profile configured to shift radially to engage a tubular groove having a matching profile as the sleeve shifts from the first sleeve position towards the second sleeve position.
