Baseline Errors Are Amplified in Subsequent Operations<\/h3>\n\n\n\n<p>Micron-level geometric errors from cutting propagate during grinding and polishing, affecting centration, thickness uniformity, and surface figure.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Micro-Damage Propagation<\/h3>\n\n\n\n<p>Micro-cracks or stress concentrations formed during cutting are difficult to remove later and can degrade thermal and mechanical stability.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Tool Wear and Repeatability<\/h3>\n\n\n\n<p>Cutting tool wear or uneven wear leads to <a href=\"https:\/\/www.nist.gov\/standard-reference-materials\" target=\"_blank\" rel=\"noopener\">batch-to-batch variability, <\/a>directly affecting consistency.
