noun
incremental coordinate
Technical term in computing and CAD/CAM, referring to coordinates expressed as offsets from a previous point rather than absolute positions.
CNCプログラムでは、増分座標を使って工具の移動を指定することが多い。
In CNC programs, incremental coordinates are often used to specify tool movements.
絶対座標 refers to absolute coordinates measured from a fixed origin, while 増分座標 specifies positions relative to the previous point.
Compound of 増分 (increment) and 座標 (coordinate). The exact historical derivation is uncertain; the term is a modern technical coinage.
