COORDINATE MEASURING APPARATUS

摘要

PURPOSE: To obtain a simple and stable structure and accurate measurement in a coordinate measuring apparatus including a column, in which one coordinate direction x is linearly movable and a measuring arm which is slidably guided in the vertical direction on the column. CONSTITUTION: A column 8 is supported on a linearly guided carriage 11 so that the column 8 can be rotated with a rotation axial line A as the center. A coordinate measuring apparatus with an especially compact structure having two linear axes and two rotation axes is obtained, wherein a third coordinate (y) which is conventionally flexible is replaced with movement in a tangential direction of a probe head 52 attached to a measuring arm 51 performed at the time of rotational movement of the column 8.
