The machine will need special jigs and fixtures to achieve these limits.įinally, very tight tolerances will need special measurement tools for quality control. It also increases the likelihood of a part falling outside the range and being scrapped. A tighter limit requires more time and labour. 060” fillet at the inner cornersįor several reasons, aiming for tighter tolerances considerably affects machining costs as well as the turnaround time.
