Explains limit vs. note form tolerancing conventions, standard representation rules for limit values, and interpretation of hole and shaft tolerances. Uses run-fit and clearance/interference fit examples to compute allowances, tightest and loosest fits. Also introduces geometric tolerancing with flatness, height, and positional/parallelism concepts, including feature control frame elements and dimensioning symbols.",{"@graph":69,"@context":122},[70,84,105],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":30,"@type":76,"position":81},"https://docshare.wps.com/document/technology/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/lecture-11-tolerancing-in-iso-limit-form-vs-note-form/662707/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/lecture-11-tolerancing-in-iso-limit-form-vs-note-form/662707.png","ImageObject",300,407,{"name":92,"@type":93},"awa","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-30","2026-10-28",true,{"@type":102,"interactionType":103,"userInteractionCount":24},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"What is the metric preferred hole-based system of fits?","Question",{"text":112,"@type":113},"It uses the basic hole as the minimum hole diameter, then calculates the fit limits based on that hole basis.
