Drill milling

Sometimes it is necessary to drill holes although at the time there is no suitable drilling tool available on the CNC machine. For such situations, the postprocessor can be enabled to carry out the drill operation as a drill milling. For this purpose, approved milling tools are cleared for this kind of application in the tool database; the most suitable milling cutter for the given drill hole parameters is selected and the drill hole is machined as a circular pocket. Drill milling is available at all geometric planes.
If multiple holes are pooled in one drill hole machining feature, the drill milling operation is carried out at each hole; however, the circular pocket milling operations are pooled together in the CNC program as a machining block so that the CNC program remains clear.
