HOW TO CALCULATE FEEDS AND SPEEDS FOR A CNC MILL

In this video you will learn how to program Feeds and Speeds and how to use formulas to calculate surface footage (SFM), Inch Per Tooth (IPT), Inch Per Minute (IPM) and Revolution Per Minute (RPM).

Thank you for explaining this so simplisticly. I have been wanting to better understand how to caluculate and use feed and speed. I get it now! And will be sure to start applying this at work!

Thanks for the feedback Michael and thanks for watching.

Thanks Philip. I'll be posting a new video every week. Remember to subscribe if you haven't already.

silly question, is this the same for lathes or is this just milling?

[@danc7262]

You make awesome videos. Do you have anything on G13, on how to calculate the IJK values?

[@TomStikkelman]

I don’t have anything on that yet. I appreciate the feedback. Tom

thank you for sharing!

Would be nice in millimetre for us guys in england but thanks this is cool..

[@alexrojasm]

How can I know the depth of the cut and the percentage of the tool that the tool resit of cut, I mean in Z and de % of the diameter of cut

[@hienaz723]

HI TOM . I LIKE YOUR VIDEO. IT IS HELPFUL BUT I HAVE A QUESTION ABOUT CALCULATE FEED AND SPEED IN LATHE. EX: I WANT TO ROUGH OD A PART HAVE DIAMETER OD .5 IN ; MATERIAL IS ALUMINUM 6061. SO HOW CAN I CALCULATE FEED AND SPEED? THANK YOU

Interesting

[@WHCAudio]

What happens when you have an endmill and material but don't know either the SFM or RPM and have no chart?

[@euclid9718]

get to know what material you are going to cut and get data about endmill you are going to use from the dealer of cutting tools

thanks

[@umargul5644]

Well

[@Eddie2774.]

thanks bro!!!!

[@indrasnath]

Sir .. I request you for speeds and feeds in metric please.. and small doubt that whether feed is same for contours and pockets ? ..plz suggest. .. thanks in advance

[@TomStikkelman]

Okay I will do a video in metric very soon.
Feeds and speeds

[@TomStikkelman]

Tom Stikkelman Feeds and speeds are based on depth of cut and amount of step over. They are calculated the same for outside profiling and pocket machining. Thanks for watching. Let me know if you have any questions.

ravin Hello Ravin. I just posted a video on calculating metric feeds and speeds. Let me know if you have any questions. Thanks
