This is why nesting your parts in the file is an important step of the designing process for sheet metal projects.<\/p>\n<h2 class=\"wp-block-heading\" id=\"h-what-is-nesting-for-sheet-metal-cutting\"><strong>What is Nesting for Sheet Metal Cutting?<\/strong><\/h2>\n<p>In the manufacturing context, the term &#8220;nesting&#8221; generally refers to the process of laying out multiple parts on a single sheet, thereby reducing scrap waste and optimizing production. This is widely used in the industry to reduce wastage and save costs.\u00a0<\/p>\n\n<p>A DXF file is the preferred format for our sheet cutting services. Dedicated CAD softwares can automatically nest your parts and export a DXF file for further operations.<\/p>\n<h2 class=\"wp-block-heading\" id=\"should-you-nest-your-parts\"><strong>Should You Nest Your Parts?<\/strong><\/h2>\n<p>Before we get into the best practices, let&#8217;s take a step back and ask ourselves if we should make an effort to nest our parts. The answer to that question will mostly depend on where you come from.\u00a0<\/p>\n\n<p>For example, if you are a manufacturer, nesting files for sheet cutting are fairly standard and often required to make the most of your available material and optimize production.<\/p>\n\n<p>From the perspective of the buyer looking to fabricate parts, it is important to remember that most sheet metal cutting shops will already have the means and familiarity with nested parts. In fact, in some cases, it can hinder the manufacturer from receiving an already nested file because it locks them into a predefined configuration that may be less than ideal.\u00a0<\/p>\n\n<p>For example, many manufacturers of sheet metal parts work with material from which parts have already been cut. It may require them to use an entirely new piece of material instead of one that they could have maxed out by nesting the pieces. Manufacturers are also more in tune with material size, machine limitations, etc.<\/p>\n\n<p>In short, sometimes it&#8217;s easier for both parties if you send your parts as individual files. There are instances where it makes sense for a customer to nest their parts ahead of time, such as when the nested file will consume an entire sheet of material, or when the customer is supplying their own material.<\/p>\n<h2 class=\"wp-block-heading\" id=\"the-impact-of-geometry-and-positioning-practical-examples-with-the-instant-quoting-engine\"><strong>The Impact of Geometry and Positioning.

Fix Common Design Errors<\/strong><\/h3>\n<p>It is very important to look for the potential design errors which create an unusable file that slows down the entire process of manufacturing. Costs incurred during design are minimal whereas, the costs of correction during manufacturing are way higher.\u00a0<\/p>\n\n<p>Hence, it is better to create an error-free file before sending it to quoting and manufacturing. Below are the common issues:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>Duplicating or overlapping lines, curves, points, etc.<\/li>\n\n\n\n<li>Unremoved information like title block information, notes, and dimensions<\/li>\n\n\n\n<li>Open geometry like open curves, disconnected lines, etc.<\/li>\n\n\n\n<li>Lines with lengths less than zero<\/li>\n<\/ul>\n\n<p><strong>Design tip<\/strong>: Export your designs as polylines to ensure that the geometry has continuous closed elements. Always ensure that non-profile elements such as titles, texts and auxiliary lines are removed.<\/p>\n<h3 class=\"wp-block-heading\" id=\"2-avoid-using-splines\"><strong>2. Avoid Using Splines<\/strong><\/h3>\n<p>Splines are the commonly used design features of CAD. They are used to produce complex geometries like gear profiles. The problem with CNC equipment is that they run on G-Codes and cannot read splines. They typically function on linear or circular movements.<\/p>\n\n<p>As a result, they read splines as lines or arcs. This leads to the loss of geometric and dimensional accuracy.<\/p>\n\n<p><strong>Design tip<\/strong>: Use lines and arcs in your design wherever possible to replace splines. Export in polylines and not in splines.<\/p>\n<h3 class=\"wp-block-heading\" id=\"3-maintain-spacing-between-the-parts\"><strong>3.<\/strong> <strong>Maintain Spacing Between the Parts<\/strong><\/h3>\n<p>Spacing is recommended between the parts to ensure the nested parts come out as desired.

They also help in keeping all the parts on the sheet after cutting, for instance, additional post processing in case of very thin material.<\/p>\n\n<p><strong>Design tip:<\/strong> It is recommended to add breakaway tabs to parts smaller than 50 mm, or for delicate features. Tabs about 0.05 mm work for most parts.<\/p>\n<h3 class=\"wp-block-heading\" id=\"5-optimise-the-parts-with-nesting-software\"><strong>5. Optimise the Parts with Nesting Software<\/strong><\/h3>\n<p>Using automated nesting functions or dedicated optimising software like Autodesk Fusion 360 (<a href=\"https:\/\/apps.autodesk.com\/FUSION\/en\/Detail\/Index?id=5430166430880711212\">download the Xometry add-in<\/a>) or ProNest can help squeeze the maximum parts into the available space.<\/p>\n\n<p>These softwares are also able to fit in complex shapes which are difficult to achieve normally. It is highly recommended to export the file as DXF after the nest optimization.<\/p>\n\n<figure class=\"wp-block-image size-full is-resized\"><div class=\"wp-block-image__wrap\"><img decoding=\"async\" src=\"https:\/\/xometry.pro\/wp-content\/uploads\/2023\/09\/Example-of-nesting-in-ProNest-software.png\" alt=\"\" class=\"wp-image-1698\" style=\"max-width:596px;max-height:358px\" width=\"596\" height=\"358\" srcset=\"https:\/\/xometry.pro\/wp-content\/uploads\/2023\/09\/Example-of-nesting-in-ProNest-software.png 1000w, https:\/\/xometry.pro\/wp-content\/uploads\/2023\/09\/Example-of-nesting-in-ProNest-software-300x180.png 300w, https:\/\/xometry.pro\/wp-content\/uploads\/2023\/09\/Example-of-nesting-in-ProNest-software-768x462.png 768w\" sizes=\"(max-width: 596px) 100vw, 596px\" \/><a class=\"wp-block-image__fancy-box-button\" href=\"https:\/\/xometry.pro\/wp-content\/uploads\/2023\/09\/Example-of-nesting-in-ProNest-software.png\" data-fancybox=\"gallery-11679\" data-caption=\"Example of nesting in ProNest software\" aria-label=\"Open full image\"><img src=\"https:\/\/xometry.pro\/wp-content\/uploads\/2023\/09\/Example-of-nesting-in-ProNest-software.png\" class=\"wp-block-image__fancy-box-button-thumbnail wp-post-image\" alt=\"\" loading=\"lazy\" decoding=\"async\"><svg class=\"wp-block-image__fancy-box-button-icon\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"18\" height=\"18\" viewBox=\"0 0 18 18\" fill=\"none\" aria-hidden=\"true\">\r\n               <path d=\"M0 2V6H2V2H6V0H2C0.895 0 0 0.895 0 2ZM2 12H0V16C0 17.105 0.895 18 2 18H6V16H2V12ZM16 16H12V18H16C17.105 18 18 17.105 18 16V12H16V16ZM16 0H12V2H16V6H18V2C18 0.895 17.105 0 16 0Z\" fill=\"#092C47\"\/>\r\n             <\/svg><\/a><\/div><figcaption class=\"wp-element-caption\">Example of nesting in <a href=\"https:\/\/www.directindustry.com\/prod\/mtc-software\/product-55535-1772381.html\" target=\"_blank\" rel=\"noreferrer noopener\">ProNest software<\/a><\/figcaption><\/figure>\n\n<p><strong>Design tip<\/strong>: Many popular CAD softwares have a built-in nesting feature.
