Thank you Don for doing this. I've been doing this by gut and how it preforms, but I like to hear all of these explanations to see if I am missing anything. Most all of what I have learned is self taught, so I am looking forward to going through your videos to see if I can learn something even if it's like this one where learning the technical info from behind the scenes.
Very enlightening , you explained a complex concept so easily. I want to know where did the SFM come from ? Is it determined by the tool manufacturer. And also how is it determined.
Machinability of a material based on its hardness and Element makeup which will add to the ability of a material to resist heat.. These are all factors in the suggested SFM. ctc
Several Ways to diagnose this Nick.. If an endmill is chipping and your setup is good, you are probably feeding it too fast and chipload is too aggressive. Bring down your chip load by either increasing your RPM ( not to slow down MRR) leave feed where it is at OR Reduce your feed and make up your MRR by increasing your radial. If your Endmill has a problem getting the chips out by loading up the flutes or excessive built up edge! Then you can do a couple things. Reduce your radial.. When we do this you will be able to take advantage of the heat and increase feed by RPM. Or Reduce the number of flutes on the tool and going back to increasing the Radial.. Axial is going to be the deflection killer.. So if your diameter to Length of cut Ratio is too great you will see a lot of chatter and deflection. Reduce your axial # 1 or #2 go with a larger diameter tool. Once you do this you can start creeping up your radial again... And Finally Remember when it comes to MRR.... A larger tool will help increase the rigidity and the cubes you remove.. If applicable. Hope this helps!! Thanks CTC

Great information, presented in an easy to grasp way! Thank you!
Good stuff Don

Anything we can do to help explain certain things better. CTC
great information! looking forward to the next one
Appreciate the Reply.. We will keep them coming.

@@CuttingtoolCounselor thank you very much for taking time to reply me.
this is good information but how do we realistically diagnose?
