Validation

What has been checked against measurement, how closely it agreed, and where the agreement stops. A simulation is only worth acting on to the extent someone has held it against a real cut, so these pages are the record of those comparisons rather than a claim about accuracy in general.

Ordered from the quantity that everything else is derived from, outward to the results a customer sees.

• Cutting Force and Torque — The correlation against dynamometer measurement, the error ranges to expect by tool type, and the two things torque predicts about the finished surface
• Temperature and Wear — Simulated cutter and chip temperature against thermal imaging, and the wear model behind the depth figures
• Cutting Force Anomaly Cases — Two production failures whose cause was invisible on the floor and obvious in simulation
• Optimization Results — Measured before-and-after on a hardened mould and a five-axis titanium roughing job

Spindle power has its own validation page under Machine Capability — Spindle Power Evaluation holds the comparison against Fanuc ServoGuide TCMD data, because what it validates is the spindle model rather than the cut.
