But they also increase the machine time and the cost of CNC machining projects significantly.<\/p>\n\n\n\n<p>The primary questions to be considered before adding a fillet or chamfer to the design are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>What is the main function of the fillet or chamfer?<\/li>\n\n\n\n<li>Is this fillet or chamfer really necessary for the part to function?<\/li>\n\n\n\n<li>How cost-effective is it to add this feature for the quantity I\u2019m producing?<\/li>\n\n\n\n<li>How can the tolerance be checked?<\/li>\n<\/ul>\n\n\n\n<p>For a better understanding of why these design and cost considerations are important, let\u2019s walk through some examples.<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"h-why-fillets-and-chamfers-increase-machining-costs\"><strong>Why Fillets and Chamfers Increase Machining Costs<\/strong><\/h2>\n\n<h3 class=\"wp-block-heading\" id=\"h-setting-up-the-tools-is-time-consuming-and-expensive\"><strong>Setting Up the Tools is Time-consuming and Expensive<\/strong><\/h3>\n\n\n<p>Initially, let\u2019s compare how fillets and chamfers are done with the CNC machining process. Chamfers are usually made with a tool that is ground to the correct angle, such as a countersink, chamfer tool or a spot drill.<\/p>\n\n\n\n<p>A chamfer tool is used to make exterior ones, while a spot drill or countersink tool is used to make interior chamfers.<\/p>\n\n\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\/countersinks-for-chamfers.jpg\" alt=\"Countersinks for CNC machines\" class=\"wp-image-2460\" style=\"max-width:758px;max-height:506px\" width=\"758\" height=\"506\" srcset=\"https:\/\/xometry.pro\/wp-content\/uploads\/2023\/09\/countersinks-for-chamfers.jpg 1000w, https:\/\/xometry.pro\/wp-content\/uploads\/2023\/09\/countersinks-for-chamfers-300x200.jpg 300w, https:\/\/xometry.pro\/wp-content\/uploads\/2023\/09\/countersinks-for-chamfers-768x512.jpg 768w\" sizes=\"(max-width: 758px) 100vw, 758px\" \/><a class=\"wp-block-image__fancy-box-button\" href=\"https:\/\/xometry.pro\/wp-content\/uploads\/2023\/09\/countersinks-for-chamfers.jpg\" data-fancybox=\"gallery-2458\" data-caption=\"Countersinks for CNC machines\" aria-label=\"Open full image\"><img src=\"https:\/\/xometry.pro\/wp-content\/uploads\/2023\/09\/countersinks-for-chamfers.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\">Countersinks for CNC machines<\/figcaption><\/figure>\n\n\n\n<p>Fillets are created with an end mill that machines the part profile. If the fillet is along a part edge, a corner rounding end mill is likely to be employed.&nbsp;<\/p>\n\n\n\n<p>However, setting up these tools can be quite time-consuming and expensive. The cutter must blend the radius into the part\u2019s top and side faces so that there are no errors and no steps remaining.<\/p>\n\n\n\n<p>In order to achieve this, the fillets along part edges (like the green fillet in <strong>Figure 1<\/strong>) are typically made with a ball-nose end mill. To achieve a high-quality fillet, the cutter is programmed to closely follow the part edge and make very small step-overs.<\/p>\n\n\n\n<p>But this makes the process expensive. Including more fillets and chamfers with high precision and quality increases the machining time significantly. In a machining environment, time is money. Hence, prior to adding an extra fillet or chamfer, consider if it is required for the part\u2019s function and worth the extra costs.<\/p>\n\n\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\/image.png\" alt=\"3D model representing a part with fillets and chamfers\" class=\"wp-image-2461\" style=\"max-width:412px;max-height:232px\" width=\"412\" height=\"232\" srcset=\"https:\/\/xometry.pro\/wp-content\/uploads\/2023\/09\/image.png 398w, https:\/\/xometry.pro\/wp-content\/uploads\/2023\/09\/image-300x169.png 300w\" sizes=\"(max-width: 412px) 100vw, 412px\" \/><a class=\"wp-block-image__fancy-box-button\" href=\"https:\/\/xometry.pro\/wp-content\/uploads\/2023\/09\/image.png\" data-fancybox=\"gallery-2458\" data-caption=\"Figure 1\" aria-label=\"Open full image\"><img src=\"https:\/\/xometry.pro\/wp-content\/uploads\/2023\/09\/image.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\">Figure 1<\/figcaption><\/figure>\n\n\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\/ball-nose-mills-for-fillets.jpg\" alt=\"Ball nose mills for CNC machines\" class=\"wp-image-2463\" style=\"max-width:744px;max-height:266px\" width=\"744\" height=\"266\" srcset=\"https:\/\/xometry.pro\/wp-content\/uploads\/2023\/09\/ball-nose-mills-for-fillets.jpg 1000w, https:\/\/xometry.pro\/wp-content\/uploads\/2023\/09\/ball-nose-mills-for-fillets-300x107.jpg 300w, https:\/\/xometry.pro\/wp-content\/uploads\/2023\/09\/ball-nose-mills-for-fillets-768x274.jpg 768w\" sizes=\"(max-width: 744px) 100vw, 744px\" \/><a class=\"wp-block-image__fancy-box-button\" href=\"https:\/\/xometry.pro\/wp-content\/uploads\/2023\/09\/ball-nose-mills-for-fillets.jpg\" data-fancybox=\"gallery-2458\" data-caption=\"Ball nose mills for CNC machines\" aria-label=\"Open full image\"><img src=\"https:\/\/xometry.pro\/wp-content\/uploads\/2023\/09\/ball-nose-mills-for-fillets.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\">Ball nose mills for CNC machines<\/figcaption><\/figure>\n\n\n<h3 class=\"wp-block-heading\" id=\"fillets-and-chamfers-are-not-wellsuited-for-low-production-volume\"><strong>Fillets and Chamfers Are Not Well-suited for Low Production Volume<\/strong><\/h3>\n\n\n<p>Production volume is another major factor that increases costs. Machining cost is inversely proportional to the parts produced and hence, low parts production means higher costs and vice versa.<\/p>\n\n\n\n<p>Moreover, adding fillets and chamfers above that low quantity increases the overall cost (see the table with cost comparison below). A large production run might be using a casting or forging process. In this case, the fillet would not only be cost-effective comparatively but also necessary.<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"how-to-reduce-machining-costs-with-fillets-and-chamfers\"><strong>How to Reduce Machining Costs With Fillets and Chamfers<\/strong><\/h2>\n\n\n<p>On evaluating those factors and deciding to add a fillet or chamfer, the next step is to consider how to machine the part at a low expense.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"design-chamfers-with-the-right-tolerances\"><strong>Design Chamfers With the Right Tolerances<\/strong><\/h3>\n\n\n<p>In <strong>Figure 2<\/strong> below, the blue hole on the top of this part is a M18 X 2 tapped hole with a 0.635mm chamfer.

The tighter the tolerance, the costlier the part.<\/p>\n\n\n\n<p>In the example shown in <strong>Figure 2<\/strong>, the chamfer diameter is noted to three decimal places, which means that the diameter of the chamfer can only deviate \u00b1 0.127mm the nominal size.<\/p>\n\n\n\n<p>A tighter tolerance would in turn increase the costs as it needs to be checked more frequently and technically a chamfer gauge would be needed for a three decimal place accuracy. Naturally, with more scrutiny and tougher measurement, the parts get more expensive.<\/p>\n\n\n\n<p>Instead, if the chamfer is changed to two decimal places for accuracy, the allowable deviation would be doubled to \u00b1 0.254mm the nominal size. This would allow you to check less frequently and use a vernier calliper instead of a chamfer gauge. If this small adjustment can be acceptable by the design, the costs can also be reduced.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"remove-chamfers-when-possible\"><strong>Remove Chamfers When Possible<\/strong><\/h3>\n\n\n<p>Removing chamfers from the hole callout can also be considered to make things less expensive and simpler (see the table below).&nbsp;<\/p>\n\n\n\n<p>For example, in <strong>Figure 3<\/strong>, the prime function of the chamfers in the side grey holes is to facilitate the easier assembly of the pin into each hole.

For example, chamfers along the part edges, like the red chamfer, are much easier and more affordable than fillets.<\/p>\n\n\n\n<p>It takes more time to set up a fillet radius tool than a chamfer tool as the tool designer has to take care that it blends with the surfaces that are joined by a fillet. In order to achieve the intended accuracy and precision, the ball nose end mill needs to pass multiple times along the fillet region.<\/p>\n\n\n\n<p>Since a chamfer tool needs less time to set up and operate, it reduces the cost compared to a fillet.<\/p>\n\n\n\n<p>If a fillet is necessary and chamfer isn&#8217;t an option, try making a standard size if you are able to use a radius milling cutter. Standard radius cutters start at 1.6mm and increase by 0.8mm. Machining a fillet with this tool is always faster than using a ball-nose end mill.<\/p>\n\n\n\n<p>The below table explains the cost variations according to the features, comparing CNC machining costs for 1, 10 and 100 parts.<\/p>\n\n\n<div class=\"custom-table-block \" id=\"table-id-160\" >\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-160\" placeholder=\"Table search\">\r\n\t<\/div>\t\r\n\t<div class=\"table-wrapper\">\r\n\t\t<table style=\"border-collapse: collapse;
