-->\n\n<!-- wp:list -->\n<ul class=\"wp-block-list\"><!-- wp:list-item -->\n<li>Surface finish is defined by three key characteristics: lay, waviness, and roughness. And technical drawings often specify roughness alone, because roughness value is the most representative parameter characterizing surface features.<br><\/li>\n<!-- \/wp:list-item -->\n\n<!-- wp:list-item -->\n<li>Ra (average roughness) and Rz (mean roughness depth) are the most frequently specified roughness parameters. In most cases, Ra is less than Rz. A rough estimation for conversion is Rz \u2248 7.2 x Ra.<br><\/li>\n<!-- \/wp:list-item -->\n\n<!-- wp:list-item -->\n<li>Don\u2019t forget to pay attention to whether roughness is specified in SI units (micrometers) or English units (micro-inches).<br><\/li>\n<!-- \/wp:list-item -->\n\n<!-- wp:list-item -->\n<li>Smoother surfaces are more expensive due to the additional manufacturing processes required. Therefore, specify the roughest acceptable finish to minimize costs.<br><\/li>\n<!-- \/wp:list-item -->\n\n<!-- wp:list-item -->\n<li>When selecting surface roughness for CNC machining, you may consider the balance between functionality and cost. Ra 3.2 \u00b5m is standard for most commercial parts, Ra 1.6 \u00b5m suits precise, slow-moving components, Ra 0.8 \u00b5m is ideal for high-precision applications, and Ra 0.4 \u00b5m, the smoothest, is used only when top-level smoothness is essential due to its high cost.<br><\/li>\n<!-- \/wp:list-item -->\n\n<!-- wp:list-item -->\n<li>In practice, surface roughness values are predetermined, meaning we adhere to a set of standards. ISO standards are widely recognized and applied globally across various industries, while ASME standards are primarily used in the United States. ISO 4287 and ASME B46.1 focus on the measurement and evaluation of surface roughness, whereas ISO 1302 and ASME Y14.36M emphasize the graphical representation on technical drawings.<br><br><br><\/li>\n<!-- \/wp:list-item --><\/ul>\n<!-- \/wp:list -->\n\n<!-- wp:paragraph -->\n<p><\/p>\n<!-- \/wp:paragraph -->","protected":false},"excerpt":{"rendered":"<p>\u88fd\u9020\u30d7\u30ed\u30bb\u30b9\u306b\u3088\u308a\u3001\u88fd\u54c1\u306e\u8868\u9762\u306b\u4e0d\u898f\u5247\u306a\u30c6\u30af\u30b9\u30c1\u30e3\u304c\u6b8b\u308b\u3053\u3068\u304c\u3088\u304f\u3042\u308a\u307e\u3059\u3002\u9ad8\u54c1\u8cea\u306e\u4ed5\u4e0a\u3052\u306b\u5bfe\u3059\u308b\u9700\u8981\u304c\u9ad8\u307e\u308b\u306b\u3064\u308c\u3001\u8868\u9762\u4ed5\u4e0a\u3052\u306e\u91cd\u8981\u6027\u304c\u307e\u3059\u307e\u3059\u91cd\u8981\u306b\u306a\u3063\u3066\u3044\u307e\u3059\u3002\u8868\u9762\u4ed5\u4e0a\u3052\u306f\u3001\u7f8e\u3057\u3055\u3084\u6ed1\u3089\u304b\u306a\u5916\u89b3\u3092\u5b9f\u73fe\u3059\u308b\u3053\u3068\u3060\u3051\u3092\u76ee\u7684\u3068\u3059\u308b\u3082\u306e\u3067\u306f\u3042\u308a\u307e\u305b\u3093\u3002\u88fd\u54c1\u306e\u6a5f\u80fd\u3001\u8010\u4e45\u6027\u3001\u5168\u4f53\u7684\u306a\u30d1\u30d5\u30a9\u30fc\u30de\u30f3\u30b9\u306b\u5927\u304d\u306a\u5f71\u97ff\u3092\u4e0e\u3048\u307e\u3059\u3002<\/p>\n","protected":false},"author":2,"featured_media":1145,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"inline_featured_image":false,"footnotes":""},"categories":[1],"tags":[],"class_list":["post-1144","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-uncategorized"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v24.4 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Surface Finish: A Complete Guide to Surface Roughness in Manufacturing- Chiggo<\/title>\n<meta name=\"description\" content=\"Surface finish is a key aspect of manufacturing and engineering.
