摘要： A signal processing portion obtains the reciprocal of a composite impedance of gap static capacitance and a plasma impedance, obtains composite static capacitance which is the sum of the gap static capacitance and a static capacitance component included in the plasma impedance from an imaginary part of the reciprocal, and obtains a resistance component included in the plasma impedance from a real part of the reciprocal. A gap detection device obtains the static capacitance component by using a model representing the characteristics of the reciprocal of the plasma impedance and the resistance component and obtains the gap static capacitance by subtracting the static capacitance component from the composite static capacitance. The gap detection device obtains a gap from the obtained gap static capacitance. Thus provided is a technique to detect a gap between a nozzle of a laser beam machine for outputting a laser beam and an object to be machined with high accuracy.

摘要： A detection unit (8) is disposed for detecting the magnitudes of f1 and f2 frequency components of a composite signal which is passed through a center electrode cable (4). A detecting signal generating unit (9) generates a detecting signal corresponding to a gap between a nozzle (5) and a workpiece (6) from the magnitudes of the f1 and f2 frequency components of the composite signal, which are detected by the detection unit (8). As a result, even if plasma occurs in the gap between the nozzle (5) and the workpiece (6), the gap can be detected with a high degree of precision.
