ABSTRACT:
A method of correcting an error in mounting a workpiece includes a step of determining a position and a direction of a tool on a coordinate system of the workpiece on the basis of command numerical values, a step of correcting an error in a preset quantity in every direction, a step of obtaining quinaxial coordinate values satisfying the position and the direction of the tool as a result of performing the error correction and a step of giving a numerical control command to a driving unit of each axis on the basis of the quinaxial coordinate values. An apparatus for correcting an error in mounting a workpiece includes an attitude detecting unit, a correcting unit, a coordinate calculating unit and a command unit that correspond to those steps, respectively. The machining can be thereby effected by correcting mounting errors that are not confined to the three X-, Y- and Z-directional position parallel movements in simultaneous quinaxial control machining without requiring a machining program.
