SELF-DETECTING APPARATUS FOR WORKPIECE-ORIGIN, MOBILE MACHINE TOOL HAVING THE SAME, AND METHOD FOR SELF-DETECTING WORKPIECE-ORIGIN OF MOBILE MACHINE TOOL USING THE MOBILE MACHINE

摘要

In a self-detecting apparatus for workpiece-origin, a mobile machine tool having the self-detecting apparatus, a method for self-detecting the workpiece-origin, the self-detecting apparatus is equipped to the mobile machine tool and includes a vision sensor and a transmitting unit. The vision sensor obtains a point image marked to the workpiece, and detects a position of a workpiece-origin based on coincidence of focuses of the points. The transmitting unit provides an information obtained by the vision sensor to the mobile machine tool. The mobile machine tool is moved to the workpiece-origin, so as to coincide the focuses of the points, based on the provided point image obtained by the vision sensor.
