Driving Efficiency and Flexibility in Tool Grinding: NUMROTO Innovations at GrindingHub 2026

Focus on measurable productivity gains

At GrindingHub 2026, NUM will present the latest enhancements to NUMROTO, which are designed to meet the key requirements of modern tool manufacturing: greater efficiency, higher process reliability, and software functions that can be specifically adapted to different production requirements.

The focus is on the new feed rate optimization feature via 3D material removal rate in NUMROTOplus. It automatically adjusts machining feed rates based on the calculated material removal volume from the 3D simulation. This is particularly advantageous for machining operations with variable material removal, such as grooving, multi-spiral tools, tapered tools, step drills, or pockets for PCD inserts.

Feed rate optimization based on real process data

With this new feature, NUMROTO expands the possibilities for machining optimization with an intelligent, simulation-based control system. Instead of setting the feedrate statically, it is automatically adjusted to the actual material removal conditions. This creates the foundation for significantly reducing grinding times without compromising on quality or tool life.

The function can be specifically tailored to the respective process. This includes, among other things, the maximum desired QW‘, the maximum permissible material removal rate, and definable feed factors during and outside of wheel contact. This is complemented by a fine-tuning function for a controlled transition during the first grinding contact. A prerequisite for optimal results is a highly precise definition of the blank used in NUMROTO.

The potential of the new function is also evident in practice. For a multi-flute milling cutter, grinding time was reduced by 14 percent. For a stepped tool with insert seats, the time savings amounted to 29 percent. Thus, feed rate optimization makes a concrete contribution to increased productivity in tool manufacturing.

NUMROTO X brings innovation and greater flexibility

With NUMROTO X, NUM presents a new product line that sets the course for the future of proven NUMROTO technology. The software, developed from the ground up, combines decades of experience with state-of-the-art flexibility and an architecture built to meet future demands.

A key development focus is on making work processes faster and more precise. New strategies for the transfer movements between grinding operations control the axes more efficiently, optimize workflows, and reduce idle time. Newly implemented algorithms ensure the necessary accuracy, delivering even more precise results.

In addition, NUMROTO X offers a significantly expanded range of configurable geometric elements. The milling cutter module includes a wide selection of predefined outer shapes for cylindrical, corner, and end face areas that can be flexibly combined with one another. This allows for the simple yet precise definition of complex geometries such as barrel or circular segment cutters.

NUMROTO X is offered in modules, with each module available in three tiers: Basic, Advanced, and Professional. With this strategy, NUMROTO X utilizes a modern licensing concept. The Infrastructure Module contains general functionalities that are essential for tool production processes. The Milling Cutter Module, on the other hand, encompasses all functions related to tool design capabilities. In this way, each user can decide whether their requirements fall under production, tool design—or both.

GrindingHub 2026 as a platform for future-oriented tool manufacturing

With the innovations presented, NUM will demonstrate at GrindingHub 2026 how tool grinding processes can be specifically designed to be more productive and flexible. The combination of intelligent feedrate optimization and modular software creates concrete advantages for companies that want to evolve their manufacturing in an economical and future-oriented manner.
