Use this tab to define drill exceptions. To define a new drilling exception, use a table to define the original drill hole that is to be replaced by a replacement drill hole. These programs can be used as replacement drill holes on machines running subprograms with special working steps (for example circular milling).
Overview of the main dialog elements:
The available drill types of the original drill hole can be selected from a drop-down list:
- Undefined
- Drill hole
- Thread
- Rectangle
- Slotted hole
- Hexagon
- Octagon
- Outline.
If the "Rectangle" drill type is pre-selected, other subtypes become available for selection:
- Square
- Chamfered
- Rounded.
1st dimension / 2nd dimension / 3rd dimension:
Size value of the original drill hole; dependent on selected drill type.

The available drill types of the replacement drill hole can be selected from a drop-down list:
- Undefined
- Drill hole
- Thread
- Rectangle
- Slotted hole
- Hexagon
- Octagon
- Outline
- NC program replacement.
If the "Rectangle" type is pre-selected, other subtypes become available for selection:
- Square
- Chamfered
- Rounded.
1st dimension replacement / 2nd dimension replacement / 3rd dimension replacement:
Size value of the replacement drill hole; dependent on selected drill type.
File name of a user-defined outline of the replacement drill hole.
Name of the subprogram on the NC machine that is to execute the corresponding drill hole (e.g., circular milling on Steinhauer machines).
Circular milled threads are known as NC programs on the machine, and can be called up as such by supplying the coordinates in the CNC file. The core hole is already generated in this NC subprogram. In the machine definition of EPLAN Pro Panel, circular milling can be defined with the associated NC program number.
To control the subprograms for circular milling (e.g., M20) on a Steinhauer machine, the following settings must be made on the Drill exceptions tab:
- Drill type: "Thread"
- 1st dimension: (diameter) "20" mm
- Drill type replacement: "NC program replacement"
- NC program replacement: Name of the corresponding machine subprogram; for M20, for example, the program "1120" must be assigned.
Notes:
- EPLAN cannot carry out any check whether the machine knows the stated program, and whether this can yield the corresponding cut-out. Therefore, this definition option must be used with extreme care. It requires precise know-how of the machine and the machine programs.
- Using this method, you cannot only replace threads, but also all other cut-out types for which there are programs on the machine.
