Tool Tuning

These examples show how to "tune" an endmill by changing its stick-out or pitch (tooth count). The endmills are all 5/8" diameter in the same toolholder, tap-tested in the same UMC-750 12,000 RPM machining center.

Picture
​Identical 1/2" 4 flute endmills in P1 material. Watch what happens to the fastest stable zone at 11,000 RPM when you change the stickout by 0.200" in and out.  You must re-tap the tool to see the change in the Dashboard.


Pull the endmill out 0.200" and the lobe shifts slower.
Push the endmill in 0.200" and the lobe shifts faster.

When would you need to use this? With the Dashboard on the left we artificially increased the maximum speed to 16,000 RPM and that revealed a stable lobe at 15,000 RPM. To try and access this lobe, we increased the endmill stick-out by 0.500", re-tapped the tool and the stable lobe moved into the machine's 12,000 RPM maximum speed. 


You can also tune the application by changing the number of teeth. We begin with a 4 flute endmill.

We added a flute and the 5 tooth endmill shifted the lobe faster.
We removed a flute and the 3 tooth endmill shifted the lobe slower.

​NOTE: We changed the number of teeth in Tool Details to generally see the effect, but to be accurate, you must re-tap test the new tool with the diffrent flute count.
