The controller then executes them in order, driving each axis with sub-millimeter accuracy.<\/p>\n<p style=\"margin: 1.25em 0;line-height: 1.9;font-size: 16px;color: #222222;text-align: justify;letter-spacing: 0.02em\">F\u00fcr <strong style=\"font-weight: 600;color: #b32050\">CNC-gedrehte Teile<\/strong> or milled housings, the tool-path sequence determines surface finish, dimensional tolerance, and cycle time.
