with commonly used contact coordinate measuring machines (CMMs) or manual gauges, such as pin or\u00a0plug gauges, presents the following limitations:<\/p>\n<ol>\n<li><strong>The inspection is slow and\/or labour intensive, and therefore often only a percentage of workpieces is inspected<\/strong><\/li>\n<li><strong>Many narrow EDM or laser-machined cavities are difficult or impossible to reach into<\/strong> with physical contact touch probes or with microscope-type gauges<\/li>\n<li><strong>Often, defects are not detected immediately, affecting the production cycle.<\/strong>\u00a0When inspection takes place in an area separate from the micro-machining station, any required correction impacts the production cycle more significantly than if the inspection were to be integrated right in or next to the micro-machining station.<\/li>\n<li><strong>Problems with machining tools\u00a0 may not be detected quickly enough<\/strong> <strong>to prevent unnecessary defect propagation.<\/strong> For example, any damage of graphite electrodes in die-sinking EDM should be addressed immediately so as to prevent machining defects in the first

non-contact 3D metrology system<\/a>\u00a0 provides machining operations with an option to boost\u00a0 quality control and therefore productivity.\u00a0 Acquiring measurements at high speed and without affecting the surface, the SURFACEINSPECT system enables complete and automated quality control of machined workpieces.<\/p>\n<p>Quick introduction \u2013the <strong>SURFACEINSPECT
