It is possible to use a smaller tooling to achieve tighter corner radii, but smaller tooling comes with some caveats. This has the chance to create chatter marks from the increased vibration of the tool, and will slow down cutting time. When the tool reaches the corner, it will need to stop and pivot. However, this is not recommended because it will cause a large amount of stress to both the tool and part. It is possible for the path of the tool to turn at 90-degrees to create a corner radius that is equal to the tool radius (the minimum possible). Trying to obtain a tight corner radius relative to the tool radius will increase how much the tool engages with the interior sides of your part, which will cause a decrease in finish quality. When CNC machining internal features, the corner radius you attempt to achieve will impact the finish of the inside of your part. The radius of the tooling employed during the CNC machining process will determine what corner radii are possible.Ĭorner radius is immensely important for CNC machining, because it will have a direct effect on the quality of the machining that can be achieved, as well as the amount of time it will take to machine a part.

This blog will delve deeper into the concept of corner radius in CNC machining, and how to choose the ideal corner radii for your requirements and budget.įor CNC machining, corner radius refers to the internal radius of the corners of your part.Īll CNC milling tools have a cylindrical shape and will create a radius when cutting an internal pocket. The corner radii you choose for your design can have a dramatic effect on how efficiently it can be machined – and the final finish quality of the machined part. With CNC machining corner radius, it is generally not possible to achieve a perfectly sharp angle on internal corners. A CNC Machining corner radius refers to the internal radius of the corners of your part.īeyond the size constraints of what CNC machinery can accommodate, another important consideration is corner radius. When it comes to metal manufacturing, every type of machinery will have some limitations on the size, angles, curves and contours that can be achieved.
