Hexagon enhances NCSIMUL platform with faster NC program verification and selective simulation technology

(IN BRIEF) Hexagon has launched a new version of NCSIMUL featuring Selective Simulation technology designed to speed up NC program verification and optimisation for complex machining operations. The new GPU-accelerated Rest Stock Preview capability enables programmers to inspect intermediate machining stages significantly faster while maintaining full simulation accuracy for final program approval. The update aims to help manufacturers reduce verification time, improve production efficiency and lower operational risk in advanced CNC machining environments.

(PRESS RELEASE) COBHAM, UK, 19-May-2026 — /EuropaWire/ — Hexagon has released a new version of its NCSIMUL software designed to help manufacturers accelerate NC program verification, simulation and optimisation processes through a new Selective Simulation capability aimed at reducing delays in complex machining environments.

The latest update to NCSIMUL strengthens the platform’s digital twin-based approach by integrating G-code verification, CNC simulation and machining optimisation into a single environment. The software is widely used by manufacturers to validate NC programs, improve machining performance and minimise the risks associated with testing complex programs directly on production equipment.

According to Hexagon, the new Selective Simulation functionality is intended to address growing pressure on manufacturers to shorten programming and production timelines while maintaining confidence in program accuracy before machining begins. This challenge is particularly significant in high-value manufacturing sectors where machining cycles can run for many hours and involve multiple operations requiring detailed verification.

The newly introduced capability uses GPU-accelerated Rest Stock Preview technology to generate intermediate stock models during the NC decoding process. These previews allow programmers to inspect how a component evolves throughout different stages of machining much earlier than with traditional sequential simulation methods.

Hexagon said the technology enables users to move more directly to critical operations within lengthy programs, helping programmers identify visible issues sooner and focus verification efforts on areas requiring closer inspection.

In one customer trial involving a long-cycle mould manufacturing application for a major American athletic footwear company, a machining program with a 47-hour cycle previously required approximately 48 minutes of sequential simulation before operators could review the required operation. Using the new Selective Simulation capability, Rest Stock Previews were reportedly generated in under two minutes.

While the previews provide earlier visibility into stock conditions and machining progress, Hexagon emphasised that complete NC simulation — including full collision detection and material removal verification — remains the required standard for final program approval before deployment to machine tools.

Jasper Sanders, Product Manager for NCSIMUL within Hexagon’s Production Software Division, said the new functionality provides programmers with a more flexible way to navigate increasingly long and complex machining programs while preserving the simulation accuracy that remains central to the platform.

The latest release also reinforces NCSIMUL’s broader role in supporting digital manufacturing workflows by helping companies optimise productivity before machining operations begin. By combining verification and optimisation within a single digital environment, the software is intended to help manufacturers improve efficiency while reducing production risk and machine downtime.

Peter Ameloot, Senior Director EMEA North at Hexagon’s Production Software Division, noted that manufacturers are under increasing pressure to maximise machine capacity, engineering resources and production time. He said the new release is designed to help verification teams focus attention more efficiently on the most critical stages of complex machining operations without introducing unnecessary delays.

The updated version of NCSIMUL became available globally on 19 May 2026.
