Apprenticeship Milestones: Relief Hammering
浮雕学徒的锤法阶段考核
标签：学徒制, 锤法, 考核, 浮雕
浮雕（压花）方向学徒的锤法考核分四级递进：①梅花锤练习——0.8 mm 铜片上打出间距均匀的浅坑阵列（100 个点误差 ≤0.3 mm）；②走线——沿直线与弧线锤出连续过渡，不得有"台阶感"；③翻面——同一纹样正面起、反面收，两面锤痕对位偏差 ≤1 mm；④成品——6 h 内独立完成 80×80 mm 花卉浮雕，评选标准含锤点均匀度与边缘无撕裂。传统师徒制下每级约 2–3 个月，现代院校压缩为 4–6 周强化课。
Relief hammering tests progress in four stages: ① dotted arrays — 100 even dimples on 0.8 mm copper, spacing error ≤0.3 mm; ② lines — continuous transition along straight and curved paths without "stepping"; ③ flip work — raise a motif from the front and close it from the back with ≤1 mm registration; ④ a finished 80×80 mm floral relief in 6 hours, judged on dot regularity and tear-free edges. Traditional apprenticeship allows 2–3 months per stage; schools compress it into 4–6-week intensives.
