Patent ID: 7823632

Claim:
An apparatus for cutting through at least two tubulars, the apparatus comprising: a control device; a robotic rotary mill cutter, said robotic rotary mill cutter comprising: a Z-axis movement device associated with said robotic rotary mill cutter, said Z-axis movement device raising or lowering a cutting device in a Z-axis in response to a signal from said control device, said Z-axis generally in the longitudinal direction of the tubulars; a W-axis motor associated with said Z-axis movement device; a W-axis rotating body rotatably coupled to said W-axis motor, said W-axis motor rotating said W-axis rotating body in a W-axis in response to a signal from said control device, said W-axis of rotation rotating about said Z-axis; a Y-axis extension device coupled between a milling spindle swing arm and said W-axis rotating body, said Y-axis extension device hydraulically pivoting said milling spindle swing arm towards or from said W-axis rotating body in response to a signal from said control device, said milling spindle swing arm capable of pivoting said cutting device beyond said tubulars; a motor rotatably coupled to said cutting device, said cutting device associated with said milling spindle swing arm, said motor rotating said cutting device in response to a signal from said control device, said cutting device capable of cutting a horizontal distance greater than the length of said cutting device; and said W-axis motor capable of rotating said W-axis rotating body simultaneously with said cutting device cutting said tubular.
