Method for generating movement path of tool

A method for generating a movement path of a tool configured to utilize a virtual path to generate a correct path that fits an allowable error, wherein the virtual path is planned through a path planning software when the tool is to be moved in a space, the virtual path includes a plurality of predetermined points, and the method for generating the movement path of the tool is configured to be implemented by a processing device, the method comprising:

• a receiving step implemented by receiving the virtual path and a precision data;
• an auxiliary point establishing step implemented by defining the virtual path into at least one non-arc section and at least one arc section and defining the at least one arc section into M number of auxiliary sections according to the precision data to correspondingly generate M−1 number of auxiliary points, wherein a quantity of the auxiliary points included by the at least one arc section is greater than a quantity of the predetermined points included by the at least one arc section;
• a moving and detecting step implemented by controlling a driver to allow the tool to sequentially move to each of the predetermined points and each of the auxiliary points in the space according to the virtual path and controlling a detector to detect three reflectors disposed on the tool when the tool is located at each of the predetermined points and each of the auxiliary points so as to generate a real-time position coordinate and two auxiliary point coordinates, wherein the real-time position coordinate and each of the auxiliary point coordinates include an X-axis coordinate value, a Y-axis coordinate value, and a Z-axis coordinate value;
• a calculating step implemented by comparing each of a plurality of real-time position coordinates with a predetermined point coordinate that corresponds to a corresponding one of the predetermined points to calculate a deviating value of an X-axis, a deviating value of a Y-axis, and a deviating value of a Z-axis between each of the real-time position coordinates and the predetermined point coordinate and calculating, when the tool moves to each of the predetermined points, a deflecting value of the X-axis, a deflecting value of the Y-axis, and a deflecting value of the Z-axis of a coordinate system of the tool that are respectively compared with an X-axis, a Y-axis, and a Z-axis of a coordinate system of the virtual path, wherein each of the real-time position coordinates and corresponding two of the plurality of auxiliary point coordinates jointly define the X-axis, the Y-axis, and the Z-axis of the coordinate system of the tool;
• and
• a correct path establishing step implemented by copying the virtual path to establish an original path, and amending the predetermined point coordinate and the two auxiliary point coordinates having the deviating value or the deflecting value greater than the allowable error in the original path to amend the original path into the correct path.
