software to simulate every process step in advance. “Granite surfaces are never perfectly flat,” says Reitz. “Using VERICUT, we simulate the operation and eliminate the risk of tool collisions or machine damage.” “Manual setup is no longer required,” adds René Maschlanka, who oversees sales and project management. “It saves time, protects the machine and increases operator confidence.” Precision workflow Granite blocks typically have a 3 to 5 mm material excess. Final machining tolerances are as tight as 5 to 20 microns, but only 0.1 mm can be removed per pass due to the stone’s hardness.
Digital twin in action Reitz uses a dedicated CAM system adapted for granite, with a custom interface to VERICUT. “We created an interface that reflects the exact workpiece geometry and position,” says Maschlanka. “This lets us simulate every operation step without manual input.” This helps detect clamping errors, unnecessary tool movements or incorrect tool use before production begins. With some jobs running over 40 hours, operators no longer need to monitor machines continuously. “The VERICUT Reviewer helps determine when checks are required,” adds Reitz. Supporting the team The VERICUT Reviewer allows simulations to be viewed on any Windows PC or tablet. “Operators and engineers can confirm the programme visually, which boosts trust and improves planning,” says Meurisse. “Our team really values the Reviewer. It highlights critical process points and supports setup tasks like tool and clamp selection,” adds Maschlanka. With VERICUT in place, Reitz Natursteintechnik has significantly reduced errors and increased machining confidence. “VERICUT is easy to use, prevents mistakes and gives our team peace of mind,” concludes Reitz. Meurisse adds: “This was an exciting challenge. We normally simulate metal – not granite. VERICUT proved it can safely handle even multi-tonne natural stone components.” n www.vericut.com/uk Measurement & Manufacturing 21
“After inspection, the operator selects a probing pattern,” explains Maschlanka. “This generates two CAM programmes: one to locate the block and one to map the surface using probing cycles.” Probing takes up machine time, so it’s used efficiently. The data is converted into NC code and run through VERICUT to verify safety before machining begins. “The surface map shows the true shape of the workpiece. From this, a machining strategy is created and simulated before cutting starts,” says Stephan Meurisse. After roughing, the cuboid is drilled for rails, sensors or spindles. Threaded inserts are glued into place, and finishing is completed in a climate- controlled lab.
