Title:
METHOD AND DEVICE FOR PREPARING ERROR MAP AND NUMERICALLY CONTROLLED MACHINE TOOL HAVING ERROR MAP PREPARATION FUNCTION
Document Type and Number:
WIPO Patent Application WO/2009/057229
Kind Code:
A1
Abstract:
In a numerically controlled machine tool which has a linear feed rod and a rotational
feed rod and in which a main shaft and a table are movable relative to each other,
the errors in position and attitude caused by the actions of the linear feed rod
and the rotational feed rod are measured at plural measurement points set within
the movable ranges of the linear feed rod and the rotational feed rod, and then,
the errors in its position and attitude are stored as an error map corresponding
to the position of the linear feed rod and the rotation angle of the rotational
feed rod.
