Meaning
Formal approval process for the removal of material from a tool surface ensures that the equipment remains within its functional specifications after sharpening. A regrind depth sign off documents exactly how much steel or carbide was removed during the maintenance of a cutting die. This record prevents the tool from being thinned beyond its safe operating limit and provides a history of the tool’s consumption over time.
Tracking this data is essential for managing the high costs of precision battery tooling.
Verification Record
Inspection teams measure the tool height and surface finish after each grinding operation. The regrind depth sign off acts as a gatekeeper that allows the tool to return to the production floor. Verification includes checking that the new surface meets the original roughness requirements for clean cutting.
Lifecycle Tracking
Cumulative material removal is tracked to predict when a die set will reach the end of its useful life. Without a consistent regrind depth sign off, there is a risk of the tool breaking under the high pressures of the stamping press. Maintaining this history is a core part of a professional maintenance program.
Dimensional Accuracy
Changes in tool height can affect the shut height of the press and the final dimensions of the battery terminals. Technicians use the regrind depth sign off to calculate the necessary shim thickness for reinstallation. Correct adjustments ensure that every part produced is identical to the first one made.
