Abstract: A method for synchronous control of a gantry mechanism with online inertia matching is applicable to a machine tool equipped with a gantry mechanism. The gantry mechanism includes two rails, a crossbeam and a saddle, in which the saddle is disposed on the crossbeam, and the crossbeam is disposed by crossing the two rails. Each of the two rails is furnished with a driving apparatus for synchronously driving the crossbeam, and the driving apparatus includes a drive motor and a lead screw. This method includes the steps of: obtaining gantry-mechanism information; detecting position information of the saddle on the crossbeam; evaluating the position information and the gantry-mechanism information to derive load-inertia variety information; and, evaluating the load-inertia variety information to adjust torque-output information of the drive motor corresponding to the respective driving apparatus.

Abstract: A contour accuracy measuring system and a contour accuracy measuring method are provided. The contour accuracy measuring system captures location coordinate data of shafts of a machine tool. The location coordinate data are calculated to obtain a first true round trajectory on an inclined plane as reference information. The contour accuracy measuring system then adjusts parameters of the locations of the shafts based on the location coordinate data of the shafts of the reference information to generate a second true round trajectory on the inclined plane, so as to get to know whether the locations of the shafts after the parameters are adjusted comply with a standard. Therefore, the overall measurement process can be speeded up by automatically measuring the parameters and automatically testing an operating status.
