CNC Machining Dimension Out of Tolerance? A QE Engineer‘s Guide to Root Cause Control and Prevention

Leave a Comment / Quality Control /

Years of frontline experience distilled — dimension deviation is hands down the most frequent quality issue on any machining floor. You know the scene: First article passes inspection perfectly. Then mid-run, dimensions start drifting. Day shift runs smooth. Night shift scraps a whole batch. Most people blame the operator. But in reality, the root cause

CNC Machining Tolerances Explained

Leave a Comment / CNC Machining /

Tolerance is one of the most important considerations in CNC machining. It determines how much a finished part is allowed to vary from its specified dimensions while still meeting design requirements. Choosing the right tolerance is essential for achieving reliable assembly, maintaining product performance, and controlling manufacturing costs. Specifying tolerances that are tighter than necessary
