Method & Evidence

AimCan an automated, in-situ endoscopic 3D measurement system accurately assess wear on hot forging dies during operation?

MethodExperimental validation and system integration

ProcedureAn industrial robot was equipped with a high-temperature gripper and an endoscopic 3D measurement sensor. The system was adapted for fringe projection measurement within the confined and hot environment of forging dies. A compressed air actuator was used to protect the sensor and mitigate refractive index issues. Wear on critical die features (mandrel radius, flash radius) was measured by comparing point cloud data to a reference geometry. Measurements were validated against a conventional system.

ContextManufacturing, specifically hot forging processes

Variables

IVPresence and effectiveness of compressed air actuator; adaptation of fringe projection to endoscopic design.

DVAccuracy and precision of 3D wear measurements on forging dies.

CVType of forging die, specific wear locations (mandrel radius, flash radius), ambient temperature (within the forging environment).

Strengths & Limitations

Strengths

+Addresses a significant gap in current manufacturing practices for hot forging.
+Demonstrates a novel application of optical metrology in a challenging industrial setting.
+Provides validated results against existing measurement systems.

Limitations

The complexity and cost of implementing such a system might be prohibitive for smaller manufacturing operations. The calibration of the endoscopic sensor in varying thermal conditions could be a challenge.

Reliability & validity

The study validates its findings against a commercially available measurement system, suggesting good validity. Reliability would be assessed through repeated measurements under consistent conditions and by evaluating the consistency of the robotic arm's positioning.

Think critically

How might the accuracy of the 3D measurements be further improved by accounting for dynamic changes in the refractive index of the air during the forging cycle?
