Method and Apparatus for Estimating Error in Multi-Axis Controlled Machine

An apparatus for estimating error in a multi-axis controlled machine, comprising:

• a machine configuration definition module for defining a topology of a machine subjected to error estimation;
• an error synthesis module for defining parameters, which represent behaviors of drive axes having geometric error and relationships between the drive axes according to the defined structure of the multi-axis controlled machine, adding the defined parameters by applying the parameters to a generalized error synthesis model, and generating an error synthesis model of the multi-axis controlled machine by applying a result of parametric modeling in response to a result of the adding;
• and
• an error mapping module for creating a virtual coordinate, which includes error of a designated shape to be processed or at a position to be confirmed, using the error synthesis model, and generating an error map, which visually expresses the produced imaginary point.
