<p>PROBLEM TO BE SOLVED: To control working correctly and constantly by eliminating an abnormal detected value extremely deviated from detected values by a plurality of sensors using a smoothing method and controlling working. SOLUTION: In respective sets, MR heights is determined by detecting and calculating resistant values R1 and R2 of a first and a second resistance lapping guide(RLG) sensors 54 and 55. The MR height is calculated by the equation HMR=(C+S.W1 )/R1 -RL), or HMR=(C+S.W1 )/(R2 -RL); RL: parameter inherent to a bar, R1 and R2 : detected resistant data). An RLG sensor showing extremely deviated abnormal value judged wholly is invalidated by using a smoothing method. That is, the detected values from such a RLG sensor are eliminated. A 4th regression curve is calculated by the MR height calculated from the resistance of remaining RLG sensors, and the MR height is ground while driving a linear DC motor in an RLG working machine to suppress the bending of a bar so that the regression curve becomes a straight line.</p> |
