However, it does come with size limitations dictated by various factors. Awareness of these constraints is crucial for optimising designs and ensuring that designs can be manufactured.<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"h-general-size-limitations-of-cnc-machining\"><strong>General Size Limitations of CNC Machining<\/strong><\/h2>\n\n\n<p>This section highlights several design tips and considerations that could improve part manufacturability while optimising cost and lead time. It discusses part complexity and CNC manufacturing constraints such as fillets, holes, pockets, threads, and undercuts.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"h-material-blank-size\"><strong>Material Blank Size<\/strong><\/h3>\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<p>This refers to the size of the raw material used to create the finished part. Material blanks typically need to be slightly larger than the finished part\u2019s measurements to allow for variations and to cut away rough faces of the raw material.&nbsp;<\/p>\n\n\n\n<p>For example, if the final dimensions are to be 50 x 50 x 50 mm, then a suitable material blank would be roughly 53 x 53 x 53 mm. When designing, take this into consideration by adding additional X, Y, and Z dimensions to your part and matching it to the part size limits below.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-large is-resized\"><div class=\"wp-block-image__wrap\"><img decoding=\"async\" width=\"1024\" height=\"1007\" src=\"https:\/\/xometry.pro\/wp-content\/uploads\/2024\/08\/blank-size-1-1024x1007.png\" alt=\"\" class=\"wp-image-44313\" style=\"max-width:346px;height:auto\" srcset=\"https:\/\/xometry.pro\/wp-content\/uploads\/2024\/08\/blank-size-1-1024x1007.png 1024w, https:\/\/xometry.pro\/wp-content\/uploads\/2024\/08\/blank-size-1-300x295.png 300w, https:\/\/xometry.pro\/wp-content\/uploads\/2024\/08\/blank-size-1-768x755.png 768w, https:\/\/xometry.pro\/wp-content\/uploads\/2024\/08\/blank-size-1-84x84.png 84w, https:\/\/xometry.pro\/wp-content\/uploads\/2024\/08\/blank-size-1.png 1180w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><a class=\"wp-block-image__fancy-box-button\" href=\"https:\/\/xometry.pro\/wp-content\/uploads\/2024\/08\/blank-size-1.png\" data-fancybox=\"gallery-22159\" data-caption=\"\" aria-label=\"Open full image\"><img src=\"https:\/\/xometry.pro\/wp-content\/uploads\/2024\/08\/blank-size-1.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><\/figure>\n<\/div>\n<\/div>\n\n\n<h3 class=\"wp-block-heading\" id=\"h-limitation-for-milled-lathe-and-drilled-parts\"><strong>Limitation for Milled, Lathe and Drilled Parts<\/strong><\/h3>\n\n<div class=\"custom-table-block table-with-white-space\" id=\"table-id-567\" >\r\n\t<div class=\"search-input-wrapper\">\r\n\t\t<svg width=\"16\" height=\"16\" viewBox=\"0 0 16 16\" fill=\"none\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\">\r\n\t\t\t<path d=\"M15.7812 13.833L12.6659 10.7177C12.5252 10.5771 12.3346 10.499 12.1347 10.499H11.6253C12.4877 9.39596 13.0002 8.00859 13.0002 6.49937C13.0002 2.90909 10.0911 0 6.50083 0C2.91056 0 0.00146484 2.90909 0.00146484 6.49937C0.00146484 10.0896 2.91056 12.9987 6.50083 12.9987C8.01006 12.9987 9.39742 12.4863 10.5004 11.6239V12.1332C10.5004 12.3332 10.5786 12.5238 10.7192 12.6644L13.8345 15.7797C14.1282 16.0734 14.6032 16.0734 14.8938 15.7797L15.778 14.8954C16.0718 14.6017 16.0718 14.1267 15.7812 13.833ZM6.50083 10.499C4.29167 10.499 2.50122 8.71165 2.50122 6.49937C2.50122 4.29021 4.28855 2.49976 6.50083 2.49976C8.70999 2.49976 10.5004 4.28708 10.5004 6.49937C10.5004 8.70852 8.71311 10.499 6.50083 10.499Z\" fill=\"#476175\"\/>\r\n\t\t<\/svg>\r\n\t\t<input type=\"search\" class=\"table-search-input\" id=\"table-search-567\" placeholder=\"Table search\">\r\n\t<\/div>\t\r\n\t<div class=\"table-wrapper\">\r\n\t\t<table style=\"border-collapse: collapse;

Tighter tolerances, defined as smaller than the general standard, can be achieved with CNC machining, reaching up to \u00b10.01 mm.&nbsp;<\/p>\n\n\n\n<p>Specialized setups and additional operations like reaming and grinding can allow for even tighter tolerances depending on the material and part geometry. Geometric tolerances (GD&amp;T) can be applied to the drawing, but these may increase inspection times due to the necessary tools and time for checking.<\/p>\n\n\n\n<p>While tighter tolerances improve a part\u2019s form, fit, and function, they have drawbacks. They can lead to higher scrap rates, additional fixturing, special measurement tools, and longer cycle times from slower cutting speeds. These factors can increase pricing and lead times. Depending on the tolerance and geometry, the part cost can more than double compared to a standard tolerance.<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"general-size-limitations-of-cnc-machines\"><strong>General Size Limitations of CNC Machines<\/strong><\/h2>\n\n\n<p>The physical dimensions of CNC machines&#8217; work envelopes are the main factor limiting their part size capabilities.

It is also important to note that the workpiece should be slightly smaller than the swing over the bed.&nbsp;<\/li>\n\n\n\n<li><strong>Swing Over Cross Slide<\/strong>: The Swing Over Cross Slide is the maximum diameter of a workpiece that can be machined when the cross slide (the part of the lathe that holds the tool post) is considered.&nbsp; The Swing Over Cross Slide is the limiting factor determining the maximum diameter of a part that can be machined using the full travel of the cross slide. For example, if a 200 mm diameter steel shaft is mounted in the lathe and you want to machine the centre of the shaft to a 100 mm diameter, your Swing Over Cross Slide will need to be large enough to accommodate the 200 mm.&nbsp;If the Swing Over Cross Slide is smaller than 200 mm, the cross slide will likely collide with the shaft. So even if the Swing Over Bed allows for a 200 mm shaft, if the Swing Over Cross Slide does not allow for 200 mm, the shaft, in this example, cannot be machined.<\/li>\n\n\n\n<li><strong>Swing Over Bed<\/strong>: The Swing Over Bed parameter represents the absolute maximum diameter of the workpiece that can be mounted.

This can be achieved in some CNC machines by removing a gap block on the lathe bed. However, one should note that this differs from machine to machine and that not all CNC machines have this possibility.

For example, deep features in the part could typically be limited by the tool length rather than the travel of the tool.&nbsp;<\/p>\n\n\n\n<p>To further illustrate this, if you were to have a part with narrow grooves, as in the image below, the tool length would be the limiting factor as the tool holder would not be able to move past the top face of the component, should the depth of the grooves surpass the length of the tool.&nbsp;<\/p>\n\n\n\n<p>In terms of accuracy, machines produced by Kern Microtechnik can achieve tolerances as tight as \u00b12 microns (\u00b10.00007 inches).<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><div class=\"wp-block-image__wrap\"><img decoding=\"async\" width=\"1024\" height=\"577\" src=\"https:\/\/xometry.pro\/wp-content\/uploads\/2024\/08\/cnc-mill-interior-1024x577.jpg\" alt=\"\" class=\"wp-image-44091\" srcset=\"https:\/\/xometry.pro\/wp-content\/uploads\/2024\/08\/cnc-mill-interior-1024x577.jpg 1024w, https:\/\/xometry.pro\/wp-content\/uploads\/2024\/08\/cnc-mill-interior-300x169.jpg 300w, https:\/\/xometry.pro\/wp-content\/uploads\/2024\/08\/cnc-mill-interior-768x433.jpg 768w, https:\/\/xometry.pro\/wp-content\/uploads\/2024\/08\/cnc-mill-interior-1536x865.jpg 1536w, https:\/\/xometry.pro\/wp-content\/uploads\/2024\/08\/cnc-mill-interior.jpg 2006w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><a class=\"wp-block-image__fancy-box-button\" href=\"https:\/\/xometry.pro\/wp-content\/uploads\/2024\/08\/cnc-mill-interior.jpg\" data-fancybox=\"gallery-22159\" data-caption=\"Deep features in the part can typically be limited by the tool length\" aria-label=\"Open full image\"2><img src=\"https:\/\/xometry.pro\/wp-content\/uploads\/2024\/08\/cnc-mill-interior.jpg\" 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\">Deep features in the part can typically be limited by the tool length<\/figcaption><\/figure>\n\n\n<h2 class=\"wp-block-heading\" id=\"cnc-drilling-size-limitations\"><strong>CNC Drilling Size Limitations<\/strong><\/h2>\n\n\n<p>CNC drilling is used to create holes in a workpiece, and the size limitations are primarily influenced by the machine&#8217;s Z-axis travel and the length of the drill bits. Thus, it is important to ensure that the drill bit length and axis travel surpass the thickness\/height of the workpiece that needs to be drilled. Another size limit is the bed size of the CNC drilling machine, which dictates the maximum length and width of the workpiece that can be drilled.<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"get-your-parts-cnc-machined-today\"><strong>Get Your Parts CNC Machined Today<\/strong><\/h2>\n\n\n<p>Understanding the size limitations of the CNC machining process is essential for optimising your designs and ensuring successful manufacturing.
