1. A method for milling and removing debris in a wellbore, comprising:
moving a collecting while milling (CWM) tool downhole into the wellbore with a wireline; and
conducting a first operation with the CWM tool, wherein the first operation comprises:
milling an obstruction disposed within the wellbore with the CWM tool, wherein the milling includes:
engaging a milling bit or other rotary tool of the CWM tool with the obstruction;
rotating a shaft of a motor of the CWM tool at a first speed to rotate the milling bit or the other rotary tool and a pump of the CWM tool;
monitoring an axial force applied to the obstruction by the CWM tool; and
maintaining a first target power consumption of the motor while milling the obstruction by modifying the axial force applied to the obstruction by the CWM tool while rotating the shaft at the first speed;
collecting debris generated from milling the obstruction, wherein the collecting includes:
disengaging the milling bit or the other rotary tool from the obstruction by moving the CWM tool uphole a first distance; and
maintaining a second target power consumption of the motor during the collection of the debris generated from the milling of the obstruction, wherein maintaining the second target power consumption includes rotating the shaft of the motor at a second speed to drive the pump to intake fluid from the wellbore to collect the debris generated from milling the obstruction, wherein the second speed is greater than the first speed.
