Path display apparatus considering correction data |
摘要 |
A path display apparatus includes a first position command acquiring unit that acquires first position command for motors, a first position feedback acquiring unit that acquires first position feedback of each of the motors, a correction data acquiring unit that acquires correction data generated for each of the motors, a second position command calculating unit that subtracts the correction data from the first position command to calculate a second position command, a second position feedback calculating unit that subtracts the correction data from the first position feedback to calculate second position feedback, a command path display unit that displays a command path of the tip point of the tool, based on the second position command; and a feedback path display unit that displays a feedback path of the tip point of the tool, based on the second position feedback. |

1. A path display apparatus that displays a path of a tip point of a tool of a machine tool, to which correction data including backlash correction and pitch correction is applied, that controls the position and posture of the tool by a plurality of drive axes, the path display apparatus comprising:
a position command acquiring unit that acquires a first position command, generated by a numerical control apparatus, for a plurality of motors that drive the plurality of drive axes, respectively; a position feedback acquiring unit that acquires first position feedback of each of the plurality of motors, from a plurality of position detectors that detect the respective positions of the plurality of motors every predetermined control cycle; a correction data acquiring unit that acquires correction data generated for each of the plurality of motors; a position command calculating unit that subtracts the correction data from the first position command to calculate a second position command; a position feedback calculating unit that subtracts the correction data from the first position feedback to calculate second position feedback; a command path display unit that displays a command path of the tip point of the tool, based on the second position command calculated by the position command calculating unit; and a feedback path display unit that displays a feedback path of the tip point of the tool, based on the second position feedback calculated by the position feedback calculating unit. |
