NUM has unveiled a major upgrade to its Numroto tool grinding software. Offering numerous additional features and enhancements, Version 4.0 is designed to increase the productivity of tool and cutter grinders without the need for additional hardware.

A notable enhancement sees ball-nose and corner radius tools in Numroto allow the programming of a helix step on end mills. For the first time, it is possible to program different helix angles for the end of the radius and beginning of the cylindrical section.
A further upgrade concerns Numroto Draw, which 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. Furthermore, all the important dimensions are added automatically to the grinding wheels. The time-saving benefits of this approach are said to be considerable: a grinding wheel assembly drawing can be printed out for the machine operator to help speed set up without having to involve the design department, which is especially advantageous for companies handling numerous small production runs.
The 3D simulation facilities of Numroto 4.0 have also been enhanced. For instance, coolant holes in the 3D blank are displayed automatically, and users can now add DXF comparison profiles. What’s more, there is a new measurement mode which provides comparator functionality, while the programmed feed rate can now be displayed during 3D simulations.
