In the Loupe TV: Utilizing SFM in CNC Applications
Join Harvey Performance Company National Applications Engineer Don Grandt in the 10th episode of In the Loupe TV: Utilizing Surface Feet per Minute (SFM) in Your CNC Applications.
In this episode of In the Loupe TV, join the “Cutting Tool Counselor,” Don Grandt, as he dives into a commonly misunderstood cutting tool topic, SFM. Learn how surface footage may be killing your end mill, and how you can start strategically manipulating your SFM to get the most productivity and tool life out of your CNC cutting tools.
Explained very well. Thank you for doing these videos. Cheers
Thanks for Watching Matthew. I will continue to try and bring relevant and current Content.

Have you guy’s updated the machine advisor pro to give us the “NEW” H.R.E.M step over percentage?
Hey Thomas,
Our team is working on getting the parameters for our SKU numbers worked out right now.
Love the logic in how this was presented. Great job in presenting this to us.
Thanks for the kind words Richard… Logic is what we strive for these days. Trying to bring a different approach to applying tools.

Harvey Tool’s “In The Loupe TV” YouTube channel provides very useful information on CNC applications explained in a way more easily grasped by all.
Thanks Josh, Glad you are enjoying them.

I don’t feel this is a great representation on comparing the two. I generally don’t run HEM at 2xd. There are great tools out there that will do full dia slotting at that depth that will blow HEM out of the water. I would love to see this test on more like 3-5xd HEM.
This is a great Comment Jared. As we know all materials, tools, and setups require a little more deep dive then I can provide in 10-15 Minutes. I am currently looking at applying the limits of the heavy radial in certain materials up to 4x the diameter. We need to find out where the diameter to length limits are in the materials we cut daily to maximize our MRR. If you have any in house data you can share it always helps complete some of my testing and expands the results. Thanks for watching and interacting.

I was just wondering what you thought about using H.R.E.M. in Copper? We machine a lot of copper , and the tooling geometry that works well in stainless also seem to work well in Copper.
Thanks for your question Dan.. A heavy Radial will work well in Copper as well. Due to some of the Properties of Copper vs Alloy steel and stainless, allows it to cut closer to Aluminum in some cases. So you can gain some of the advantages of SFM and Heavy Radial..
What is SFM , you intimated it is RPM . I always though this was ‘ feed rate ‘ and a combination of RPM and federate determines how much material is removed .
Hi Hedley,
SFM is your Surface Feet per Minute. This is found by multiplying your cutter diameter by your RPM/speed and dividing it by the industry standard constant of 3.82.
