Designing for Cost Effective CNC machining
In the competitive world of custom part manufacturing, achieving costeffectiveness without compromising quality is the ultimate goal. For businesses relying on CNC machining services, the design phase is the most critical lever for controlling final part cost. By integrating Design for Manufacturability (DFM) principles early, you can significantly reduce expenses and accelerate production for your projects.
One of the most impactful strategies is designing with standard tooling in mind. Custom tools increase cost and lead time. For instance, specify radii that match standard endmill sizes instead of arbitrary dimensions. Avoid deep cavities that require long, fragile tools, which necessitate slower feed rates and multiple passes. Furthermore, minimizing the number of setups directly cuts cost. A part that can be machined in three setups instead of five saves on programming, fixturing, and manual labor. Design features to be accessible from as few orientations as possible.
Internal vertical corners will always have a radius due to the cylindrical nature of end mills. Instead of specifying a sharp corner, design with a standard radius and a matching undercut if a 90degree angle is functionally necessary. This eliminates the need for EDM or handfinishing, which are costly secondary operations.
Material selection and stock size are other major cost drivers. While a specific alloy might be ideal, a more machinable alternative with similar properties can drastically reduce machining time. Collaborate with your manufacturing partner to select the optimal material. Additionally, designing a part that utilizes a standard stock size, rather than a custom bar or block, minimizes material waste and cost.
Wall thickness is another crucial consideration. Excessively thin walls are prone to vibration during machining, leading to poor surface finish and potential scrap. Very thick walls consume excessive material and require more machining time, driving up the price. Aim for uniform and adequate wall thickness to ensure stability and efficiency.

Finally, standardizing hole sizes and thread types across your designs reduces the need for tool changes. Using the same drill and tap for multiple holes streamlines the CNC program and machining process.
