ABSTRACT:
A measurement control method uses an ending target position Xes calculated by adding a prescribed length Ls to a measurement ending position Xe. A rotation rate pattern Ar for rotating a screw2, a back pressure Ps in relation to the screw2, and a retraction rate pattern Ab for the screw2to retract, are set in advance. The remaining rotation rate pattern Ar to stop the rotation of the screw2at the ending target position Xes from the detected screw position X, is calculated at the time of measurement, and the rotation of the screw2is stopped based on the calculation. Further, the remaining retraction rate pattern Ab is calculated from the detected retraction rate Vd, and the retraction of the screw2is stopped based on the calculation. The result is the stopping of the screw at the measurement ending position Xe.
