Truly the leader in cutting tools. You corrected a lot of mistakes I was making that was costing me money. Very in-depth discussion that I will need to re-watch multiple times
Really excellent information! Helped a rookie get a more theoretical understanding of cutting mechanics and giving better insight into creating better processes
Thanks, Justin! We're glad you enjoyed the webinar. We'll have another webinar about chip thinning soon. You can check out our full schedule here: kmt.co/webinars
Thank you, thank you, thank you!! Really informative. Suggestion: is it possible to talk (and show) a bit more about how you measure the tempererature, tool load, all that. Do big machine shops do that of measurements in-house to improve the productivity or do they usually ask you to go there and help out? Thanks
We appreciate your question! You're timing is good, we are recording the next part of the series today and I will address it directly in the webinar for you. As soon as we have it uploaded we will make sure to add a link here to it. Thank you!
Great webinar - im curious on your experience of how the cutting speed impacts the optimal chip thickness? Is it in fact decoupled, so that i can find the optimal chip thickness, and then determine the most suitable speed dependent on the ae and the tool life that i search for?
Articulate and clear content. There is one thing I am wondering though. I am aware that setting up Ae and Ap is highly dependent on the situation considering the rigidity of the setup etc. but is there any webinar or source that I can go through for adjusting Ap and Ae based on the applications?
With this information, I'm looking for general SFPM for various materials, general recommended chip load (feed per tooth), and I would also like to see minimum chip load. The minimum chip load would be used for getting the clean finish and avoiding rubbing in the process. I'm not sure if you guys are working on the app (since it seems to have been down for a little while). If you are, all the dynamics of this information as well as the finishing FTP would be very handy.
Hi Tony - I will pass your comments along to Steve and Danny and perhaps they can do a webinar around general SFPM and chip load/minimum chip load. Thanks for the suggestions!
@@KennametalInc the more I understand chip thinning the more I wonder if I have been programing all my feeds and speeds wrong. Instead of going off of SFPM and adjusting my FPT, it seems like I should have been looking at ideal FPT and calculating SFPM based on % tool engagement or TEA.
Tony, you have the right idea. Ideally you would select a FPT, then adjust it for the radial depth of cut, and then also adjust your base SFM based on the radial engagement percentage. So in the end you should compensate both from the base values, and usually I play with speed more than feed if I know the FPT is already in the right range. Hope that helps!
@@KennametalInc it really sounds to me that as long as I keep the optimal FPT at the point of engagement, my only limitation is the machine. Focusing on either max rpm or max feed while keeping FPT.
At 26:10 you guys show in the picture "Chip thickness has to be more then the edge radius". Does the avarage chip thickness or the maximum chip thickness (Fz) needs to be bigger then the edge radius? As long as I understand the concept of chip thickness and how to make all the calculations. I'm looking for something/someone who can tell me what minimum/maximum avarage chip thickness to aim for. I could imagine that there is no maximum chip thickness, the chip can be as big as the insert/holder can manage. But maybe the answer on the question above could give me clearity of what minimun avarage chip thickness to use.

Again the WEBINARS !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Hello Gentlemen,
How do we calculate arc of engagement?
Could you please share the formula?
Thank You

You've got it Tony! It's about finding those optimal parameters one step at a time as you identify machine limitations, setup limitations, etc.

I could imagine that there is no maximum chip thickness, the chip can be as big as the insert/holder can manage.

Hello, I like for the minimum theoretical chip thickness to be at least 2x the edge radius.
@@dannydavis705 you mean 2x edge radius as minimun avarage chip thickness I assume?
Danny and I prefer to use the maximum chip thickness for that analysis, especially when climb milling.
