The roughing tool setting unit 131 calculates a height of a machining area including a reference step height of a preset electrode when the analysis information of electrode modeling is input from the search module 110, and according to the calculated result, the database 120. From among the standard tools stored in the tool, a roughing tool that is optimal for the height of the machining area is determined and set.

This means that if you use a tool that is too large for the contour, the first roughing itself may proceed quickly due to the large amount of step over, but the amount of uncut geometry will increase, which will require more time for heavy residues. When the workpiece height is high due to the characteristics of the graphite electrode, there are many electrodes for processing the edges of the main core, so the first roughing tool selection is based on the Z axis height value rather than the tool selection considering the X and Y area of the material. To be selected accordingly.

If there is no corner part as a result of the determination of the rectangular corner search unit 133, the minimum of the blended place of the electrode 3D model is detected. The radius size is detected and the minimum tool diameter is calculated from the detected minimum radius size so that a residual tool of that size is set.

In addition, the minimum tool diameter search unit 134 calculates the minimum tool diameter using a formula of (minimum radius value where the 3D model is blended-the discharge gap of the electrode) × 2 After comparing the minimum tool diameter with the tool information stored in the database 120, the tool having the largest diameter among the tools having a diameter smaller than or equal to the minimum tool diameter is set as the final residual tool.

In addition, the tool path setting unit 136 automatically sets the gap between finishing and roughing for electric discharge machining to be used for each finishing tool path, and further sets the tool down and step-over according to the tool diameter and the cutting method. Create toolpaths that apply macros to lead, link, reference tool settings, boundaries, tolerances, spindles, and feed conditions to automatically apply the optimal values.
