Measurement jig for measuring precision error caused by multi-axis synchronized motion

Abstract

A measurement jig for measuring precision errors caused by multi-axis synchronized motion is provided and includes: a stand vertically fixed to a table of a machine tool; a first support transversely disposed at an appropriate height of the stand to connect with a first measurement component; a second support vertically disposed on the first support and keeping a distance from the stand to connect with a second measurement component and move relative to the first support; and a third support vertically disposed on the first support between the stand and the second support to connect with a third measurement component and move relatively to the first support, wherein the first, second and third measurement components measure precision errors caused by a multi-axis synchronized motion and examine the precision of the Tool Center Point (TCP).

Dependencies are inferred from the claim text.
