Hexagon has added a feature to the latest version of NCSIMUL that allows for quick verification of intermediate processes in long-duration machining programs. This reflects the demand from manufacturing sites to reduce the time spent on iterative verification during the verification process of complex NC programs.

Hexagon’s Production Software business unit announced on the 28th that it has released the latest version of NCSIMUL, an NC program verification software, and applied optional simulation features.

NCSIMUL is software that provides G-code verification, CNC simulation, and machining optimization functions. Manufacturers utilize it to identify potential machining errors and conflicts before applying the program to actual equipment.

The newly added optional simulation feature allows users to examine the workpiece status of a specific process step in advance, without sequentially executing the entire long machining program. It works by generating an intermediate material model during the NC decoding phase through GPU-based residual material preview.

Hexagon also revealed a test case from a global sportswear company in the United States. In a 47-hour mold processing program, the existing method took 48 minutes to verify the desired process, but when the new feature was applied, a preview of the remaining material was generated within 2 minutes.

However, the final verification procedure is maintained. Before applying the equipment, collision detection and material removal accuracy are verified through full NC code simulation.

Jasper Sanders, Product Manager at NCSIMUL, stated, “Selective simulation is a feature that helps review necessary processes more flexibly in complex programs,” adding, “In the final stage, the existing simulation engine is utilized as is.”

The latest version of NCSIMUL has been available since May 19, 2026.
