Grinding Dressing and Truing: Surface Exposure and Geometric Form Differ

Separate the two functions

Norton distinguishes truing of wheel shape and alignment from dressing of its grinding-face condition. They can occur together without becoming the same function. Primary reference: Norton technical explanation.

Compare fictional before-and-after records

Imagine a wheel with a fictional radial profile deviation and a face whose cutting points are visibly worn. Observation A documents corrected profile but supplies no new evidence about the face. Observation B documents refreshed face condition but retains no profile measurement.

Neither record alone demonstrates both outcomes. If one conditioning operation is claimed to achieve both, retain separate before-and-after evidence for each. This is a diagnostic worksheet; it supplies no wheel-speed, tool-contact or conditioning procedure.

Preserve two verification questions

Create a profile/alignment field and a face-condition field with their own observation methods. Keep the relevant wheel, abrasive and conditioning-tool identities beside them. Record which claim is supported after the actual operation rather than using the word dressed as a catch-all result.

An appropriate real procedure depends on the specified wheel and equipment documentation. The useful outcome here is a clear request for evidence of geometry and cutting-face condition. It avoids approving a wheel because one result improved while the other was never checked, and it predicts no grinding quality from either observation alone.
