<p>PURPOSE:To improve the offset processing efficiency by checking the interference between the environmental form including a material to be processed and a using tool and using the plotting algorithm to form a tool route where a processing enable area is expressed positive. CONSTITUTION:A processing part for formation of a tool route includes a form data input part 100, an offset processing part 110, and a formation processing part 120 using the plotting algorithm. Thus a tool route screen is obtained with calculation of luminance information in addition to a tool route (NC data) using the plotting algorithm. Then an environmental form including an object form, etc., is converted into a three-dimensional model using a CSG model and the offset processing is carried out in response to the using tool diameter to replace the using tool with a linear tool. In addition, the offset processing is carried out with the offset value set in consideration of the finishing margin. Thus the processing efficiency is improved with formation a tool route.</p> |
