NC Record: Principle

An NC record is an NC program that can drill and mill an outline on a machine. In this context, the focus is on the specific possibilities of the machine and its tools. The outline is created graphically in the outline editor and equipped with the machine-specific information by generating an NC record.

If all dialog values are set in the NC outline record dialog, a starting point is set on a straight line of the outline. The milling path is drawn on it as a graphical representation of the NC program via the outline.

Note:

The program prevents that a starting point can be placed too closely to arcs, to a rounding or a corner point of a rectangle. Such an input is ignored. The status bar indicates the incorrect position, and you are prompted to define another starting point.

Representation of milling paths and drilling points

Milling paths

Each end point of a program step (straight or arc travel) is indicated by a circle (1). The milling path is represented by parallel lines, arcs or circle segments (2).

Color-based identification of drilling points and position markers

Blue: Position of pilot drill hole (1)

Green: Position of the milling cutter above the workpiece (2)

Red: Position of the milling cutter within the workpiece (3).

When the milling cutter goes in or out of the material, this happens in the same X/Y position, i.e., a red circle and a green circle are generated in the same location. In order to differentiate the travel in and out visually, the second circle (program step) is drawn somewhat smaller than the first one:

Place additional drill holes

To manipulate the outline, it is possible to include additional drill holes in the milling outline. The selected drill is placed in these locations. The drill hole can be placed freely or on the snap points of the outline.

Place fins

Fins are break points in the milling path that are placed in straight outline segments in the stated width. The material remains in these locations. The required pilot drill hole is generated automatically at the same time.

Color-based identification

Red: Travels of milling cutter in the material (1)

Green: Travels of milling cutter above the material (2)

Blue: Pilot drill hole (3).

Generated NC records

Notes:

The generated NC records are entered into the outline file after the closing of the outline. When generating the NC export, the outline and NC record are transferred to the NC program and output to the machine-specific output files. The outlines can be viewed as milling paths in the software of the driven machine.

To render visible the NC records stored in an open outline, use the View > Next NC record and View > Previous NC record functions.
