6. Width of Cut, Length of Cut & Selecting Tooling!

Let's discuss WOC, LOC and criteria in selecting tooling!

This video was very informative; I learned a lot and am thankful for the information you presented (as usual in an entertaining, professional and pleasant way). Thank you. Now I'm on my way to Lakeshore Carbide to order more sensibly. The one tip regarding stub end mills was invaluable.

You never cease to amaze me... I am sooo happy, that you're opening a school :-) People need you... Especially ME... lol

[bluehandsvideo]

Gotta say that I love and appreciate the way you explain things!! Awesome!!

Superb ! Ty . I’m just starting out (my second hand desktop cnc mill arrives in the next few days - so this is immensely helpful to help with initial tool selection)

Its not difficult to use, takes a bit to get used to using it, and to set the relief angles correctly. It may take an hour or so to get acquainted with the machine, endmills can be sharpened and back in service in a few minutes.

I sure enjoy your videos! I have been a maintenance type machinist for 50 years, but cnc less than 4 years, still learning a lot.

Going back to my comment on the # of flutes video, this is how I get away with using 4 flute endmills instead of 3 in aluminum. I generally use a high RPM, a low chipload and I use dynamic toolpaths (HSM, trochoidal, etc) that do a good job of clearing the chips. Combined with high flow coolant, I have little issue with recutting chips. :)

I completely agree with using the shortest endmill you can manage. Much stronger. I also suggest using the largest diameter endmill that you can manage. My general purpose roughing endmill is 1/2" with 1.25" flutes.

3:15 couldn't agree more... recently went to a 10mm DOC and a 1.2mm WOC on my cnc router... Nearly quadrupled my MRR now around 15 cubic cm a min! better surface finish and huge chips too, easier to clean up.

I have a Darex endmill sharpener, it will sharpen the ends and the flutes as well, it is the model E90 and has an air spindle I bought it several years ago. when I was machining 304 ss machine parts.

A idea from Mr Seebold, freelance Tormach consultant, is that he ONLY uses the very end of his end mills until they get dull, then he rounds them up, and gets them all ground SHORTER. This way he loses none of the cutter diameter, gets an increasingly rigid tool, and only pays to grind it down which sounded cheaper than sharpening. This would naturally require shallow work though so I still try to do all of my work full length.

Check your math at 4:25 for what is 30% of .125"

[TheMudfly]

Are these good guidelines for manual machining too?

[impba]

I agree with the short endmill theory! I grind my endmills, ends and flutes, and have a lot of

Some very good tips there. Of course now I have to buy radiused end mills ... 😏

Awesome episode, keep up the fantastic content.

Thanks for all the informative videos. Great job!

Sometimes you need the long tool for the .050 on hard to reach places.

John I had a tormach a few tears ago. I sold it. Im thinking of getting another. Do you have a problem with the TTS tool holders pulling out of the spindle. I know there is maintance procedure for the TTS R8 collet. How often do you do maintance on the collet. Thanks

[brandonedwards]

Send your tooling out to be reground and sharpened to save money and use more of the carbide.

[holmes]

That was an excellent video, makes you think, loved it,

Smaller depth of cuts faster speed is faster than deeper cuts 30%. Less pressure on your part as well.
