Before cutting costs, it is important to understand what a fillet is actually doing for your part. They are not just there to soften a design’s look; they are highly functional engineering features.<\/p>

Adding a fillet smooths out the geometry, allowing that stress to flow and distribute over a much larger surface area. This simple design change drastically improves the part’s load-bearing capacity and long-term fatigue life.<\/p>

<\/p>

\ub514\uc790\uc778 \uaddc\uce59:<\/strong> Use a minimum fillet radius of 0.015″ to 0.030″ (0.4mm to 0.8mm) on any load-bearing internal corner. Even a micro-fillet provides exponentially better fatigue resistance than a sharp edge.<\/p>

Applying a convex fillet blunts this vulnerable edge, instantly improving the component’s durability. Just as importantly, it removes razor-sharp burrs, making the part significantly safer for operators, end-users, and assembly technicians to handle.<\/p>

While they certainly add aesthetic value to consumer-facing products, cosmetic fillets should be applied with caution. Even though they are “just for looks,” they still consume real machine time, require specific tooling, and increase the final invoice.<\/p>

<\/p>

\ub514\uc790\uc778 \uaddc\uce59:<\/strong> If a fillet is strictly cosmetic, loosen its tolerance on the engineering drawing (e.g., \u00b10.010″ instead of \u00b10.002″). This allows the machinist to run the tool faster without worrying about discarding the part over a minor visual deviation.<\/p>

If you design an R0.030″ internal corner, the machine shop cannot use their robust, standard 1\/4″ tools. They are forced to use a delicate end mill with a tiny diameter of 0.060″ or smaller just to fit inside that corner to clear out the material physically.<\/p>

<\/p>

\ub514\uc790\uc778 \uaddc\uce59:<\/strong> Always design internal corner radii at least 0.020″ (0.5mm) larger than the radius of the standard tool you expect the shop to use. This prevents the tool from engaging 90 degrees of material simultaneously, eliminating corner squeal, tool wear, and chatter.<\/p>

If you design a 2-inch deep pocket but specify an R0.050″ internal corner, you are asking a tiny cutter to reach deep into a solid block of metal. This forces an extreme 20:1 L\/D ratio. Standard tools cannot achieve this without snapping, forcing the shop to buy expensive, specialized long-reach tooling or utilize highly complex machining setups.<\/p>

<\/p>

\ub514\uc790\uc778 \uaddc\uce59:<\/strong> Keep the internal fillet radius (R) strictly greater than 1\/5th of the pocket depth (R > Depth \/ 5). For a pocket that is 1 inch deep, the corner radii should be no smaller than 0.200″ to allow for rigid, standard-length tooling.<\/p>

Machine shops base their pricing and efficiency on their stocking levels. Using standard fractional or metric tool sizes (e.g., 1\/8″, 1\/4″, 1\/2″ or 3mm, 6mm, 10mm). If you design an arbitrary internal radius of 0.137″, the machinist cannot simply plunge a standard 1\/4″ tool (which creates an R0.125″ corner) into that pocket.<\/p>

\ub514\uc790\uc778 \uaddc\uce59:<\/strong> Match your fillet sizes to standard end-mill diameters, plus a small clearance. For example, if you want a shop to use a 1\/4″ end mill (Radius 0.125″), design your corner as R0.140″. The cutter can then smoothly sweep the corner in a continuous motion without stopping.<\/p>

Every time a CNC machine stops to change a tool, it adds 10 to 20 seconds of “dead time” to the cycle. If you design a part with an R0.125″ pocket, an R0.200″ slot, and an R0.250″ internal wall\u2014all on the same face\u2014the machine must perform three separate tool changes to clear those corners.<\/p>

This phenomenon, often called the “dog-bone effect” or “edge nodulation,” can throw off critical tolerances and cause the coating to flake off during assembly.<\/p>

<\/p>

\ub514\uc790\uc778 \uaddc\uce59:<\/strong> Apply a minimum external fillet of R0.015″ to R0.030″ (0.4mm to 0.8mm) on any edge that will receive a plated or anodized finish. The curve evenly distributes electrical current, ensuring a uniform coating thickness.<\/p>

Tight internal corners suffer from the opposite problem. In powder coating, a sharp internal 90-degree corner creates a “Faraday Cage effect.” The electrical charge of the corner actively repels the powder particles, leaving the deep corner bare or dangerously under-coated.<\/p>

<\/p>

Similarly, in wet plating processes, viscous liquids and acids can become trapped in tight, sharp corners. If these fluids are not completely flushed out, they will slowly seep out over the next few days, causing an “acid bleed-out” that permanently stains and ruins the surrounding finish.<\/p>

The larger the internal radius, the larger the end mill the shop can use. A larger end mill is exponentially stiffer, allowing vastly higher feed rates and deeper depths of cut. A pocket machined with a 1\/2″ tool will be finished in a fraction of the time it takes to machine the same pocket with a 1\/8″ tool.<\/p>

<\/p>

\ub514\uc790\uc778 \uaddc\uce59:<\/strong> Push your internal radii to their absolute functional maximum. If an R0.250″ corner works just as well mechanically as an R0.125″ corner, always specify the R0.250″.<\/p>

Leaving an internal corner completely sharp (R0.000″) on a CAD model is the most common and costly mistake in digital drafting. If the shop receives a model with a sharp internal corner, their quoting software will flag it as requiring highly specialized tooling or EDM processing, instantly inflating your quote.<\/p>

If you apply a blanket \u00b10.005″ tolerance to your entire drawing, you are forcing the machinist to constantly stop the machine, inspect the part, and measure cosmetic edge-breaks with high-precision gauges. This slows down production and increases the scrap rate for parts that fail inspection for purely visual reasons.<\/p>

<\/p>

\ub514\uc790\uc778 \uaddc\uce59:<\/strong> Explicitly separate critical functional radii from cosmetic ones on your 2D drawings. Use a title block note that states: “ALL UNTOLERATED COSMETIC RADII TO BE R0.015″ \u00b10.010”. This gives the shop the freedom to run fast without compromising its critical dimensions.<\/p>

Machine shops use standard fractional or metric end mills. If you design a corner with an exact radius of a standard tool (e.g., an R0.125″ corner for a 1\/4″ end mill), the tool will screech and chatter as it hits the corner because 90 degrees of the cutter engages the material simultaneously.<\/p>

<\/p>

\ub514\uc790\uc778 \uaddc\uce59:<\/strong> Always design internal fillets to be slightly larger than standard tool sizes. Add a minimum of 0.020″ (0.5mm) to the standard tool radius.<\/p>
