Drill Exceptions: Principle

In machine-based manufacture, it depends on the machine in use whether the required drill hole type can be generated. For example, a laser can produce exact hexagons, but a milling cutter cannot. This is not set definitively in the parts data, because it is not known yet which machine will be used for the manufacture.

For each machine, for DXF output and drilling templates, specific drill exceptions can be defined in the settings. This way, drill holes that cannot be manufactured on one machine are replaced by another type that the machine can manufacture.

When exporting NC drill data, then, the alternatives are exported rather than the originals. In the case of real machines, after the exception, alternative processing triggered by missing tools is also selected (if the thread cutter is missing, drill only core hole, etc.).
