開朗 基羅 不只 是藝 術 家， 同 時 也
是減 法製 作大 師，他 常 說 他 所 做
的事情就是將作品從束縛它們的大理石
中解放出來。今天，感謝有各種機具，
我們不需要成為拿著鑿子的藝術家也能
將各種「物件」從困鎖它們的發泡材、
樹脂或木材中解放出來。這些讓我們的
作品從海浪泡沫中躍起的機具稱為電腦
數 值 控 制（
computer numerical control
，
CNC）機—也就是說這是一種可以透過
電腦控制其他工具（如銑切、車床、研
磨與鑽洞）的機具。
CNC 機具
跟 3D 列印機一樣，CNC 機具其實不是
什麼新玩意：它們早就被用來製作高精
度的機械零件。這些機器通常又大又貴，
由鑄鐵所製成、填滿小砂礫來降低震動，
並且小心翼翼地安裝在不是人人可進入
的廠房之中，這樣做當然是安全考量。
這些 CNC 機具本質上就是台機器人，可
在一定空間中移動工具來製作物件。在
減法技術中，這些可移動的工具可能是

銑切
雷射光、刀具、超音速水刀或旋轉機具
等，重點是要能夠用來切除材料。
數位革命不能不考慮到 CNC 機具。所以
幾年前在網路上出現了一系列開放原始
碼專案，希望能幫助自造者在自家車庫
就能做出 CNC 機具。
當 然， 這 些 家 用 機 具 在 精 度 上 無 法 跟
工 業 用 的 機 具 相 比（ 例 如
圖 13-1
中 的
ShopBot 5 軸 CNC）， 但 已 足 以 滿 足 自
造者的需要。有些大品牌推出了低價的
「桌上型」款式，所占空間大概只要 4 平
方英尺。
