Engineering term for aligning a workpiece or tool to the center of a machine, such as a lathe or milling machine.
Before machining on the lathe, carefully center the workpiece.
芯出しが不十分だと、加工精度が落ちる。
If centering is insufficient, machining accuracy will decrease.
Standard kanji spelling for the engineering term 'centering'.
Alternate spelling using 心 (heart/center); less common than 芯出し.
Compound of 芯 (しん, 'core, center') and 出し (だし, nominalized form of 出す 'to bring out'), literally 'bringing out the center'. The spelling 心出し uses a different kanji for 'center'.
