Let’s talk about the number of teeth on an endmill. The top left panel shows the frequency response function, or FRF, for an endmill. This describes its natural frequency, stiffness, and damping. We obtain it from a tap test, where we excite the tool with an instrumented hammer and measure the response with an accelerometer. The other three panels show the stability maps for 25% radial immersion down milling in aluminum using an endmill with the displayed FRF (800 Hz natural frequency). The only difference is the number of teeth. We see that the best spindle speed-axial depth combination (green circle) changes with the number of teeth. As we add teeth, the stability peaks tend to squeeze together at lower spindle speeds. The simple equation shows the approximate relationship between the best spindle speed, natural frequency, and number of teeth. To learn more, register for our ACE CNC machining course.

Let’s talk about chip thickness in milling. Two results are shown: one for stable down milling (bottom left) and one for unstable/chatter down milling (bottom right). For the stable cut, we see that the chip thickness, h, never actually reaches the commanded feed per tooth value. This is because the radial immersion is less than 50%. For the unstable/chatter cut, we see that the chip thickness does not repeat and drops to zero more often than the stable cut. This is because the instantaneous chip thickness depends not only on the feed, but also the cutter vibration and the surface left by the previous tooth. The stability map that let’s us choose stable conditions is shown in the top right panel. The only parameter we changed here was spindle speed.

Precision Machining of Closed Impellers for Optimal Efficiency! ⚙️💨 Ensure flawless performance in demanding applications. #PrecisionMachining #ClosedImpellers #OptimalEfficiency #EngineeringExcellence

Inefficiency, potential damage to the tool, workpiece and machine, unnecessary cost and waste due to downtime – we are talking about excessively long chips. This is one of the most common issues encountered in turning, especially with soft materials due to their susceptibility to malleability. However, this problem can be easily avoided by following a few straightforward strategies: ✅ Pronounced chip breaker geometries on the rake face ✅ Use smaller insert radii and larger setting angles ✅ Optimise cutting data: At higher feed rates and lower cutting speeds, the chips break very well and are under control. ✅ Finally, the chip breaker geometry will not work properly if the depth is too small.
