Process names are not quality levels by themselves; the required tooth, runout, hardness and interface results are what matter.<\/p>\n<p>Heat treatment can move the part, so machining allowance and final datum recovery should be planned before hardening when tight gear, bore or shaft relationships are required.<\/p>\n<\/div>\n<\/div>\n<\/section>\n<section class=\"sg-section sg-section--soft\">\n<div class=\"sg-container\">\n<div class=\"sg-section-head\">\n<h2>Practical design and replacement implications<\/h2>\n<\/div>\n<div class=\"sg-split sg-split--flip\">\n<div class=\"sg-prose\">\n<p>Inspection should match the acceptance plan.
