Simplified 2D drawing software from Num

Num has launched a unique 2D drawing tool, NumCAD, which simplifies the design and creation of G-code executable files for CNC cutting machines.

NumCAD runs directly from the operator panel of the machine and also under Windows on any standard PC. According to Num, its user interface mimics that of many popular CAD packages and is very intuitive, making it ideal for people with minimal design experience.

Simple drawing tools are provided for functions such as line, polyline, 2P arc and arc center radius; they are supported by a suite of editing tools such as Meet Two Lines, Shrink or Extend and Insert Micro Joint, which allows users to customize and modify shapes.

If a user already has a CAD file, NumCAD allows importing AutoCAD DXF files. If the user does not have a DXF file, but has created the shape on the CNC cutting machine itself, NumCAD also allows this shape to be imported from its library of customizable parametric shapes.

According to Num, the NumCAD software package includes a post-processor; shapes or patterns that have been drawn or imported can be automatically converted into a G-code executable file for the CNC cutting machine.

Using NumCAD, each segment of a cut can be set to fast, marking, coarse, medium, or fine cut qualities. Both standard shape and custom fly-cut capabilities are available, and related features include the ability to control the placement of the cut side (kerf compensation) and the tilt angle of the cutting nozzle from the machine. Nesting gives the user the ability to create complex paths containing the same pattern. With parameters such as nesting type, number of parts, sheet size and scaling, Num indicates that the user can create a path sized and optimized as desired. Added alignment parameters allow shapes to be rotated and offset for minimization and optimization of uncut space.

  • Lathes/mills on the B axis have their place

    The additional rotary milling axis of these machines allows them to make many types of complex parts in a single setup, but these machines have gained a reputation for being difficult to program. Today’s CAM software, however, makes the programming challenge much easier.
