If your measurement uncertainty is large relative to the tolerance (especially on critical-to-fit features), you need either a better measurement setup (fixtures, probing strategy, environment) or a tighter decision rule (guard band + escalation).<\/p><h3 class=\"wp-block-heading\" id=\"72b3b353-d549-4cdc-8673-e204b005edaa\">4) Which dimensions are most critical when buying aftermarket shredder knives?<\/h3><p>Thickness and parallelism (stack control), bore\/drive interface geometry (torque transfer), bolt-hole true position (assembly repeatability), and any seating faces that define clearance.
