In-process inspections are done at the intermediate points in fabrication and assembly. They’re scheduled checkpoints after certain steps have been completed but before proceeding to the next operations, so any defects or drift can be caught and corrected early. This position in the workflow lets you verify that each stage produced the correct tolerances, fits, and surface conditions before more work builds on it, reducing waste and rework later. Beginning-stage checks focus on materials and setup, while end-stage checks look at the finished product, so the most effective balance for catching issues without slowing production is to perform inspections at these intermediate, or middle, stages. For example, inspecting after a machining step that determines fit with a mating part ensures that any mismatch is addressed before assembly continues.
