CNC Tolerances Explained: How Tight Is Too Tight? A Practical Guide for Engineers Executive Summary Tighter tolerances are not always better. They increase cost, reduce yield, and limit supplier options—often without improving function. Key points engineers should remember: Tolerance should follow function, not habit or legacy prints Every extra tenth adds cost exponentially, not linearly
