The best file format for CNC machining is STEP (.step or .stp), the neutral solid-model standard defined by ISO 10303. STEP stores exact boundary-representation geometry (faces, edges, and vertices), so CAM software reads a watertight solid instead of an approximation. IGES (.igs) is the older neutral alternative from the early 1980s and is now treated […]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[13],"tags":[],"class_list":["post-29476","post","type-post","status-publish","format-standard","hentry","category-cnc-machining"],"acf":[],"_links":{"self":[{"href":"https:\/\/leweiprecision.com\/zh\/wp-json\/wp\/v2\/posts\/29476","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/leweiprecision.com\/zh\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/leweiprecision.com\/zh\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/leweiprecision.com\/zh\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/leweiprecision.com\/zh\/wp-json\/wp\/v2\/comments?post=29476"}],"version-history":[{"count":1,"href":"https:\/\/leweiprecision.com\/zh\/wp-json\/wp\/v2\/posts\/29476\/revisions"}],"predecessor-version":[{"id":29480,"href":"https:\/\/leweiprecision.com\/zh\/wp-json\/wp\/v2\/posts\/29476\/revisions\/29480"}],"wp:attachment":[{"href":"https:\/\/leweiprecision.com\/zh\/wp-json\/wp\/v2\/media?parent=29476"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/leweiprecision.com\/zh\/wp-json\/wp\/v2\/categories?post=29476"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/leweiprecision.com\/zh\/wp-json\/wp\/v2\/tags?post=29476"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
