ABSTRACT

Provided are a robot control device and a plasma cutting method that are
capable of appropriately cutting a workpiece at the cutting position on the
cutting surface of the workpiece while keeping a constant distance between the
tip of a torch and the surface of the workpiece. A robot control device
includes: a robot control unit that controls an operation of a plasma cutting
robot according to a teaching program; a distance calculation unit that
calculates a distance between a torch and a cutting position on a cutting
target; a posture calculation unit that calculates a posture of the torch
relative to a cutting surface that contains the cutting position on the
cutting target; and a correction unit that corrects at least a position of the
torch in an adaptive direction orthogonal to the cutting surface on a basis of
the distance calculated by the distance calculation unit and the posture
calculated by the posture calculation unit, to keep a cutting distance for
plasma-cutting the cutting target. The robot control unit controls the
operation of the plasma cutting robot with at least the position of the torch
corrected by the correction unit.
