When measuring a part, what should be your next step if the result is outside the desired tolerance?

When the measurement of a part reveals that it is outside the desired tolerance, the appropriate next step is to adjust the tool offset accordingly. This action addresses potential issues directly related to the machining process that may have caused the variation in the part's dimensions.

Adjusting the tool offset allows for immediate corrections to be made in the machining process, ensuring that any discrepancies are compensated for in subsequent operations. By fine-tuning the tool offsets, the operator can achieve better accuracy in the machining process, which is critical for maintaining product quality and adherence to specifications.

The other options do not effectively resolve the issue at hand. Simply re-running the part without any changes can lead to repeated errors. Stopping the machine and reporting the issue is a necessary procedure in certain contexts, but it does not contribute to a resolution for the current manufacturing cycle. Changing the workpiece material is also impractical and unnecessary if the root cause of the discrepancy lies with the tool offsets. Adjusting the tools can effectively correct the current situation and improve the overall machining process.
