摘要
The tool radius compensation method of the present numerical control apparatus is to prevent a mark from being left on a workpiece by calculating a tool path so that a micro straight line is not generated when correcting the tool radius. In this method, a program for numerical control is read in units of one command Analyze; As a result of the command analysis, if the command is not the program end command, the state of the tool gap correction flag is checked; If the tool diameter flag is set, analyze the contents of the tangent block; When the relationship between the tangent blocks is not generated as a result of the analysis of the block content analyzing step, the target position is calculated by performing tool radius correction in the same manner as in the conventional method, and the calculated target position is outputted for driving the motor; In the analysis of the block contents analysis step, when a tangent line is generated, a line is corrected so that the progress speed of the tool is constant at the connection point between the adjacent inbound blocks, And outputting an intersection for driving the motor.
