Undercut machining refers to the process where CNC machined parts look “done” in CAD but fail on the shop floor, especially when producing undercut parts in machining that require specialized undercut cutting tools that typical straight machining tools cannot achieve. The geometry is not the problem by itself. The problem is access: the cutting edge has to reach material that …

In hard milling vs wire edm, the decision usually comes down to precision, speed, and cost considerations. Many engineers struggle to choose between these two methods without a clear comparison of capabilities. Hard milling removes material quickly but is affected by tool deflection, vibration, and wear when machining hardened metals, making it unattended operations less reliable for delicate profiles. Wire …

Internal corner radii are one of the fastest ways for a CAD model to turn into a slow, risky, high-quote CNC milled part, especially when avoiding sharp internal corners. For CNC Internal Corner Radius decisions, the key is designing for end mills with an appropriate tool diameter to radius. As noted in CNC machining design best practices, sharp internal corners …
