To provide a metallic surface trimming method and a manufacturing method of a billet which can detect and respond to abnormality occurring in processing in an early stage.SOLUTION: A metallic surface trimming method is operations shaving down the thickness of a metallic surface in which a sound pressure level occurring in processing is measured to adjust a scarfing allowance or a grinding allowance according to the sound pressure level. A manufacturing method of a billet comprises: a carry-in process which carries a billet into a machine scarf; an insertion process which inserts the billet into a processing position in the machine scarf; a scarfing process which performs scarfing of a surface of the billet; a scarfing operation being arbitrarily selectively performed which includes an imaging process that images a surface of the scarfed billet, and a grinding process that automatically grinds a portion of the billet surface requiring trimming obtained from the imaged surface picture as needed by using a grinding truck and an invert traverser; and scarfing allowance adjustment according to a trimming method of the metal surface at the time of scarfing the billet surface in the scarfing process when repeatedly performing the scarfing operation of next billet from the carry-in process after completing the processing of the billet.SELECTED DRAWING: Figure 1 【課題】処理で発生する異常を早期に検知し対応をとることが可能な金属表面の手入れ方法および鋼片の製造方法を提供する。【解決手段】金属表面の厚みを削る作業であって、処理で発生する音圧レベルを計測し、音圧レベルに応じて溶削代または研削代を調整する、金属表面の手入れ方法である。マシンスカーフに鋼片を運搬する搬入工程と、マシンスカーフ内の処理位置まで鋼片を装入する装入工程と、鋼片の表面を溶削する溶削工程と、を含み、任意選択的に、鋼片の溶削した表面を撮影する撮影工程と、必要に応じて、研削台車および反転トラバーサを用いて、撮影した表面写真から得られた、鋼片表面の手入れ必要箇所に対し自動研削を行う研削工程と、を含む溶削作業を実施し、鋼片の処理終了後次の鋼片に対し搬入工程から繰り返し溶削作業を実施する際に、溶削工程における鋼片表面の溶削時に、金属表面の手入れ方法に従い溶削代を調整する、鋼片の製造方法である。【選択図】図１
