Abstract
PURPOSE:To omit the correction of a program data and to improve the operation rate of a machine by detecting the lack of accuracy on the machine side, previously storing a deflected variable and allowing a numerical controller side to correct table traveling. CONSTITUTION:The traveling accuracy of machine side is measured after compling assembling, the measured value is inputted to the numerical controller as correcting value data and the traveling accuracy of a working machine at the time of real working is secured without correcting a numerical control program itself. ?When the direction of each control axis is deflected from the direction of a logical control axis, the deflected variable is measured is each control axis, a moving distance in each control axis direction which is obtained until the deflected variable goes to the length of a minimum moving command unit is calculated and the calculated value is previously stored as a correction parameter. Then, operation is executed based on a current position and a correcting parameter, and at the time of each movement control or after ending the movement, outputs a corrected axis moving command to execute the correcting movement of the table.
