Num’s simplified 2D drawing software

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 machine’s control panel and also under Windows on any standard PC. According to Num, its user interface mimics that of many popular CAD software packages and is very intuitive, making it ideal for people with minimal design experience.

Simple drawing tools are provided for such features 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 expand, and insert micro-joints, which allow users to customize and modify shapes.

If a user already has a CAD file, NumCAD can import AutoCAD DXF files. If the user does not have a DXF file, but 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; the shapes or patterns that have been drawn or imported can be automatically converted to a G code executable file for the CNC cutting machine.

Using NumCAD, each segment of a cut can be set to fast, mark, coarse, medium, or fine cut qualities. Standard and custom on-the-fly cutting features are available, and related functions include the ability to control the cut side placement (kerf compensation) and the tilt angle of the machine’s cutting nozzle. Nesting gives the user the ability to create complex paths containing the same pattern. With parameters like nesting type, number of parts, sheet size, and scaling, Num indicates that the user can create a dimensioned and optimized path as desired. Added alignment settings allow you to rotate and offset shapes to minimize and optimize uncut space.


  • Hard milling is not just high speed machining

    Milling complex shapes in hardened tool steel involves more than quick and light cuts, explains the medical injection mold maker. Here are some of the ingredients for an effective hard milling process.

  • Sophisticated software for solid gear design

    Whether your IT platform is stand-alone or part of a suite, desktop, or in the cloud, there is an equipment design package developed specifically to meet your needs.

  • Program a robot like you program a CNC machine tool

    Programming a robot with the same CAM software as that used for a multi-axis machine tool eliminates the need to “teach” the robot by manually moving it from one point to another and recording these point movements. point as robot motion controls. Robotmaster is a software package that provides this CAD / CAM based offline programming for robots. It works fully integrated into Mastercam CAM software for CNC machine tools.
