Abstract:
A period of time during which a laser beam moves through an inner region of a beam spot that ranges from a center of the beam spot to an area corresponding to a thermal energy of 44% with respect to a total thermal energy of the beam spot is set as a moving time tp. “c”, “ρ”, “λ”, “T”. “T0”, “A”, and “Pd” respectively represents a specific heat, a density, a thermal conductivity, a melting temperature, an environmental temperature, a light absorptance, and an energy density of the inner region. A time calculated from Equation (1) is set as a melting time tm. A plate thickness is represented by x and a value of tm/tp is represented by y. The value y is set between a lower limit value (Equation (2)) and an upper limit value (Equation (3)). tm=c ×ρ×λ×π[( T−T 0)/(2× A×Pd )] 2    (1) y=0.0027e 0.36x    (2) y=0.0026e 0.4512x    (3)

Claim (Index 1):
A laser processing machine comprising:\n a laser oscillator configured to emit a laser beam having a wavelength of a 1 band; and a laser processing unit configured to cut a plate material of aluminum having a material code of 1000 series by irradiating the plate material with the laser beam emitted from the laser oscillator and moving an irradiation position of the laser beam relative to the plate material, wherein a period of time during which the laser beam irradiated on the plate material moves through an inner region of an area of a beam spot of the laser beam that ranges from a center of the beam spot to an area corresponding to a thermal energy of 44% with respect to a total thermal energy of the area of the beam spot is set as a moving time tp, in a case where \u201cc\u201d represents a specific heat of the plate material, \u201c\u03c1\u201d represents a density of the plate material, \u201c\u03bb\u201d represents a thermal conductivity of the plate material, \u201cT\u201d represents a melting temperature of the plate material, \u201cT0\u201d represents an environmental temperature, \u201cA\u201d represents a light absorptance of the plate material, and \u201cPd\u201d represents an energy density of the inner region, a time calculated from Equation (1) is set as a melting time tm during which the plate material is melted,\n tm=c \u00d7\u03c1\u00d7\u03bb\u00d7\u03c0[( T\u2212T 0)/(2 \u00d7A\u00d7Pd )] 2  \u2003\u2003(1), and \n in a case where a plate thickness of the plate material is represented by x and a value of tm/tp obtained by dividing the melting time tm by the moving time tp is represented by y, the laser processing unit cuts the plate material by setting the value y between a lower limit value obtained from Equation (2) and an upper limit value obtained from Equation (3).\n y=0.0027e 0.36x  \u2003\u2003(2) \n y=0.0026e 0.4512x  \u2003\u2003(3)
