<p>PURPOSE:To finish a work of high workmanship if the working amount of a workpiece per unit length of a tool course by computing said amount per work unit according to the tool course and setting the tool feeding speed parameter on the basis of the computed value. CONSTITUTION:When the dimensions of a workpiece 9 to be cut, the material thereof and a tool used as the cutting tool are decided, the tool course is generated. The tool course is divided, it is determined whether the cutting-out action is the first work unit 6a of the divided working units, or not, and if the first working unit 6a is to be performed, the tool feed speed parameter is set to higher value. When the second work unit 6b and subsequent work units is performed, relating tool feed speed parameters are set to lower values. Then the feed speed is set from the factors of the set-up tool feed speed parameter, the material of the workpiece 9 to be cut, the tool 19 and so on, and the working unit and the working data are fed to a machine tool. Thereafter, it is determined whether the working unit is the final working unit, or not, and if the unit is not the final one, repeat said actions and if the unit is the final one, the working action is terminated.</p> |
