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. |
