thanks for showing metric infos :)

Thanks for adding metric numbers! Please keep them coming :)

Really enjoying these longer full depth video. Love seeing the subtle differences of how things are done across the water as well. Keep it up john and the team.

Instead of "break link" @ 10:58, change the projected lines into construction geometry to keep the parametric properties of the sketch.

John; I know you are in love with that adaptive cycle. It does have its uses for inside pocketing. For slotting you may find a alternate method for this part would be faster and more reliable. When you have time try this. Take your 1/4" endmill with the tip radius and make slotting passes at very shallow depth of cut. You didn't say (Or I don't remember) how deep your slot was. Lets say .150" deep. Take ten passes at .015 depth at 10,000 RPM and 100 IPM what was your width lets say 3" of distance so 3 x 20 passes = 60" at 100 IPM that = .6 minutes. See with adaptive you are cutting air about 30-50% of the time. With this shallow depth of cut in slotting with the tip radius endmill you are basically doing feed milling (The tip radius thins the chip) the tool won't load up. Actually you may find you can feed even faster than 100 IPM that's only .0033 feed per tooth of your 3FL endmill. This method of milling makes a thicker smaller chip that is easer evacuated by coolant or your air mist for slotting operations. With bigger parts and with a proper feedmill, this is the most efficient way to rough parts now days. It does require more horse power than the Tormach might have. Your Haas would do it fine. Look into feed milling.

All my Tuesday wishes came true! Thanks, John!

one of your best ever videos John, and I've watched them all. Thanks!

Your tool broke because your chip load was too low. You need to feed faster or take a larger WOC. You need to make a decent size chip so that the heat can be taken away with the chips instead of transferring to the tool or part. I say it in almost all of your videos, but HSM milling is a waste of time in aluminum. You can run full slotting at 1XD depth no problem.

Thank you for the conversions right in the vid!

I work with Inventor and used to have similar issues of not being able to select geometry similar to this. However, in this situation, you actually didn't have any geometry to select other than what you projected. Create the entire rectangle and make sure the points lock/constrain to the corner points on the projected geometry and it will still be parametric. In Inventor, you can hover over the line to select other geometry, I imagine Fusion has the same feature since they are both Autodesk products.

awsome tutorial i will be watching this over over again and again thanks!

Thank you so much for the metric info and good content

Hey! thanks for the metrics!!! so much easier to follow

Thanks for sharing where to find the good set screws for the set screw holders. I've been trying to find the good set screws for a couple weeks now. Also, not many guys show the art of flipping the part so thanks for sharing that as well, and don't be afraid to show how you flip the part in your upcoming videos as well....Always interesting.

You know what's really cool? I'm not a machinist (not cool, yet) but, having learned so much on this channel, I immediately spotted that the mill needed tramming, right before John mentioned it. Good stuff!

Cool stuff! Going to manage a bit complex part exactly the same way

This channel is fantastic.

We all love Adaptive, but sometimes? Slotting is the proper technique.

Agree on the Autodesk needing to improve partial projected sketches. Trips me up non stop all the time.

Know what’s even faster than the 3/6”? 1/4” endmill full width ramp slotting 😁 If you had set up a stop on the left side when doing op 1, and picked your Z zero as the top of your parallels. Instead of futsing around with all those sketches in op 2. You could have just picked the upper left corner at the bottom of the model box for your op2 position. No need to re establish your XYZ zeros in the machine. Just flip, and put the finished edge against the stop. And done. Also. No need to face on op 1. You’re already running a horizontal path later. Just have it do the top as well.

Big thx for metric!

there is good information here, nice job.

John relay like the new updated web site. A lot of good info there many I am working on setting for my company. Thanks

what blade do you use on your saw for aluminum?

Great video, well beyond my pay grade

like that you added metric parameters :) u rock

Hi John, i appriciate your knowledge, but could it be better to take a roughing mill with cropshape and rough the whole slot out, change the tool to a end mill and finish the sides and the bottom with it? I work with this setup quite very good, especially by big parts out of aluminium with roughly more tha 300-500 cm3³ to remove.

I'd love to hear more on your touchscreen: what brand and technologies work well in the shop?

Yep, at 19:58 you can clearly see that the head is slightly rotated counter clockwise, and needs some trimming :) It takes a secondary cut going to the right, and not whne going to the left

John, instead of breaking the link to model in your sketch, try adding short lines on the top and bottom edges to close the loop of the region you want to retain. This works in almost all parametric CAD programs and it works in Fusion 360 as well.

I only have a 3D printer but this shit is fkn sick 👌 Keep it up man!

Soak the end mill in a lye solution and any aluminium built up or welded on will be disolved quickly.

Here is how you save your tool after chipmelting without breaking the flutes!! Put it in almost boiling hot water with some caustic soda. And it literally eats the aluminium away. You end up with a brand new tool. ;) even if there are massive chunks. 20-40min and done.

Thanks for metric info....

Can you tell me what is the make and model of the larger microscope camera ($800-$900 range)?

If you use coolant it would cut that slot from your shop to Sacramento California. We used one 1/4" 3-flute Accupro for 11 months one time.

Sense the last thing you do on both op1 and op2 is the chamfer on the outside edge, with that tool loaded could you have gone in and just broke the edge on your through holes to save you time deburring later on by hand?

NYC CNC, where to buy the best quality end mills?

I think you could make the projected shape construction line and draw a rectangle over it

Hi, What CAM do you use or recommend?

What is the brand of the microscope that is connected to the display?

Sodium Hydroxide is your friend for removing aluminium from carbide tools :)

use Lye/Sodium Hydroxide to clean the alu off endmills

17:15 I love your videos but I am not going to pee on my keyboard to project :P

When I tried to do 2d adaptive for similar kind of slot I get bunch of of G1’s in the code and machine(Haas) shakes a lot.any possible solution?

What is the best method to get out sticky aluminium chips from a carbide endmill?

Thanks for the "rest of the world" units! :)

I’m not going to lie, 13 year old me laughed when you said “p on your keyboard”

Why didn’t you just slot the tool through the center of the “fins” of the heatsink, and then come back with a contour operation to clean up the sides?

I peed on my keyboard but it didn't seem to work. Also now it isn't working. Help?

Have you tried using the "break" line just below the extend function? This should create 2 separate line segments instead of the 1 constant line

5:57 The WOC was rather too small. You need to cut the chips, not smear the aluminum around or weld it to the cutter. And some mist coolant always helps with aluminum.

I was going to suggest you just plow the groove and not screw around with adaptive, but about 1000 folks have already done so. Instead, I will suggest you get some roughing mills, and plow the groove and stop screwing around with adaptive :)

On your radius, you could also invest in some uh... radius tools? So 1 pass around the part and its done. Tool paid for itself in 2 jobs.

Never heard of Coby monitors ??

We use full depth slotting all day every day in our job job. WAY less wear and tear on the machines servos and screws and way less programming and in aluminum with carbide?... who cares. OR like John said in a past video, use the largest tool you can? How about 5/16" tool, 1 pass rough, 1 pass on each side .001" cleanup.... 3 passes would take about 30 seconds.

Your becoming to reliant on adaptive milling, those slots should just be slotted, it is only aluminium. Your tools and machines can easily do this and you will save plenty of cycle time. Don't be afraid.

If you've got aluminum chips welded to your tool, throw it in some lye, the lye will breakdown the aluminum and leave the tool alone.

10:02 this is like threading a needle

That heat sink looks optimized for surviving rugged handling rather than for peak thermal performance. #intriguing

Why not just contour the slots leaving .01 on the walls and the floor? That is, take it all in one full depth leaving .01. I would take a full depth using all 180deg of the cutter.

Stop being afraid to take a cut your videos are great just got to take a cut

Don't bottom the drill in the chuck before tightening, and also don't chuck on the flutes, unless you like broken drills. (Think about it: the drill tip applies torque to the drill shaft, trying to untwist the flutes. This causes them to expand in diameter a small amount. This causes a stress point at the place the hardened flute contacts the tip of the chuck jaw, and can chip the flute. This can lead to a fracture and break the drill off at the end of the chuck jaws.)

I did everything you said and it doesn't allow me still to do anything on the flip side..... I hate this damn Program

For the slotting why the complex tool path just 3/16 cutter feed the f outta it do yuor offset and feed back....no?

Don't throw that endmill away, it is a perfect candidate to be resharpened by a shop that does that.

Too much work corner rounding tool

Use 1 or "O" flute tools to keep chip welding aluminum particularly in the absence of flood coolant. Aluminum can actually be machined most effectively at 3000SFM but it is absolutely necessary to have 1 flute tools to make that kind of cut sustainable in the absence of flood coolant but at more conventional SFM which you are utilizing it is also surprisingly advantageous to use 1 flute tools for aluminum machining. Check out datron CNC, they make their own 1 flute tools some of which feature patented special geometries, but many of the less expensive 1 flute endmills perform well for this application.

Lol sloting it would be faster doe

CANT YOU DRAW A RECTANGLE TO FINNISH THAT AREA?

Heat sink? Really? And still not cutting a decent chip, I see. ;D

Changing the toolpath in Fusion and putting it onto the Tormach surely takes much longer than just running it the full slot again...

If you see that kind of machining times on a simple, shallow open slot. You should do a sanity check and think again what's going on. Compare the slot length and your feed rate, does it make any sense? Absolutely not. It's absurd.

Why bother re cramming the part just adjust feed and WOC and run it again

In this case slotting would have been far faster and more reliable.

"Horizontal" fillets are a great intellectual exercise but a massive waste of time on 99% of parts.

Wasted 5 minutes to save 40 seconds... hmmm
