March 21, 2018 — NUM has launched a release of its NUMROTO tool grinding software. Version 4.0 of the software is designed to increase the productivity of precision machine tools without the need for additional hardware.
The ball nose and corner radius tools in NUMROTO now allow programming of a helix step on end mills. For the first time, it is now possible to program different helix angles for the end of the radius and the beginning of the cylindrical parts.
NUMROTO Draw, the software’s drawing and documentation tool, automatically processes the geometry data used for grinding a tool to generate a basic drawing. Many NUMROTO users choose to provide this drawing together with the finished, ground tool to their customers, to show standards compliance. The latest software release extends this capability by automatically displaying the geometry of the grinding wheels and grinding wheel packages needed to make the tool in the drawing. Also all the important dimensions are automatically added to the grinding wheels.
The 3D simulation facilities of NUMROTO Version 4.0 have also been further enhanced. Coolant holes in the 3D blank are displayed automatically, and users can now add DXF comparison profiles. There is a measurement mode which provides comparator functionality, and the programmed feed rate can be displayed during the 3D simulation.
First launched in 1987, NUMROTO software is designed for manufacturers of machines for the production and re-sharpening of tools such as end-mills, drills, step drills, form cutters and many others. It is currently used on 5,500 machines worldwide.
