Abstract
A tool travel path creating method for a numerical control device comprises the steps of reading G-code program; determining whether or not any correction command is included in the read G-code program; determining whether or not the interior angle between a first vector, being a line segment from a start point of correction to a work starting point, and a second vector, being a line segment from the work starting point to an work ending point, is acute when a correction command is included in the read G-code program, and then creating a tool travel path to be corrected in accordance with the following steps: calculating and storing data for a third vector starting from the work starting point and with a direction perpendicular to the first vector and the same length as the radius of the tool; calculating and storing data for a fourth vector starting from the work starting point and formed by adding the second vector to an intermediary vector with the same direction as the second vector and the same length as the radius of the tool; a fifth vector starting from the work starting point and with a direction perpendicular to the second vector and the same length as the radius of the tool; and, calculating and storing data for a sixth vector starting from the work starting point and with the same direction as the first vector and a length of 2.sup.1/2 times the radius of the tool.
