- How to Machine Richlite on the Tormach PCNC 1100! From kitchen countertops to fixturing and die work, Richlite has been around for over 70 years and is a highly versatile material but since it's composed of layered paper, DELAMINATION with traditional tooling was a concern BUT with a Harvey Tool Compression Cutter, it machines beautifully. In this job shop job, we used the new Dust Shoe we made in last week's Wednesday Widget; not only to keep the machine clear of debris for viewing, but as a safety precaution.

"it can catch fire" so, let's build an ashtray out of it :)
Thinking the same thing. Also who CNCs an ashtray???
Someone whose customer pays them to I suppose.
My HS shop teacher (who taught me how to run mills, lathes and other metalworking processes) was a cigar buff. Not my first choice of project, but if one has the money and the want, it will happen.
hahah you got me first :p
They might use it as a model for casting
Idea: Add a LED light to the dust shoe so we can see better. Great Video tho.
Same thought here... beat me to it...
Was just about to post the same thing!
John, do you have that 100mm 4" ring LED I gave you a Summer Bash or two ago? 12v It would be perfect on the shoe, seal it in place with some rings cut on the laser and sealed with silicone
Appl Tom
No, no. He says it provides a nice image for the video camera. No problem here. 😉
Just like on the Haas, where the view is effectively obscured by coolant.
That compression bit is genius, thanks for explaining!
A really helpful and well made video as usually, so much info in there that i need to go back over and that needs to researched.. and thanks for the info that this material is a fire risk!
Nice one. I really enjoy the trips down into the guts of f360. Thank you
This is way better than the ash tray I made in pottery class in elementary school
Interesting. What brand CNC did you kids have there?
CLAY brand.
Oh wow. you guys had the CLAY. We had used the "Little Fingers" CNC in our school. Model 10.
you answered all my question in the first minute thanks great video
Cool Material....
afaik compression cutters, also called up-down cutters are commonly used for wood to avoid chip out on both sides
That's correct. Especially plywood.
And as Tom Lipton showed, router bits will cut metals just fine.
They're also used on routers to avoid having to tab your parts to the main sheet. The cutter compresses sawdust into the backside of the cut locking the part in the sheet. When you're done with the run, remove the sheet from the spoilboard (table) and knock the parts out. Nice and clean and saves a huge amount of time from both cutting tabs (and sanding) along with the previously mentioned backside chipout issues. A real help when you have dozens of parts nested into a 4x8 sheet of material...
That's a real exotic ashtray
That part looked cool. I wish there we're more glamour shots of it at the end.
Hope those cigars don't set it on fire….
Richlite seem to have neglected to say what resin they use, or to provide a proper Safety Data Sheet (MSDS) for those machining their materials.
Whilst the bulk material is safe, do NOT breathe in the dust or vapours given off by machining or laser-cutting these resin-laminated materials.
Have good fume and dust extraction.
i was just thinking of a tool wit opozing flutes but more for debured miling and you may get this a lot but can you edit in in screen metric units for your speeds and feeds keep up the good work
You should add some LEDs to your vacuum adapter, would make for a great shot
Is it possible to plug the dust collector into one of the outlets on the back of the tormach like the coolant pump is? Would it draw too many amps? Could use an M Code to turn it/off, but you may want to adjust code some so it keeps it on more often, wouldn't be good on collector to keep toggling it.
Hey John. I've never thought of using scallop for 3D chamfers; I've always tried to use the 2D trace but it doesn't like to actually make the chamfer, despite having input boxes for changer parameters just like 2D contour. Have you ever gotten that to work?
Chris DePrisco
I've made it work, I do rememeber it being a little fiddly though. It seems to be made for ball mills and it will work better if the chamfers aren't modeled.
Hirudin Weird. I just tried it on a part last night and when I set the chamfer width (and picked climb milling since it won't automatically...) it did offset to the outside but regardless of what I enter in the chamfer tip offset, it won't step down at all. I ended up using a negative stock to leave and just guessing since it was just an edge break.
Chris DePrisco
Ah... negative stock to leave. That sounds familiar.
I need to go back and look at some scallop toolpaths, think you just solved a problem I've been having 🤔
I think the opening in the dust shoe should be moved more to the spindle side
cool but you kinda missed the boat on being able to put a badass radial tool path in the center of the cigar tray, unless of course the customer didn't want that
How, John, did you come up with the Area Smoothing parameter??? Yes it's there for scallop ops, but my Google Foo does not show ANY reference to this "hidden" parameter. Was it Rob Lockwood, a "in" at Autodesk, or a little green martian (The Great Gazoo)? Anyway another great vid, and a tip I hope to remember.
Is a paper-based product suitable for a hot ash receptacle?
Richlite can catch fire, so be carful. We are making an ash tray! :)
Richlite is good to 350 degrees. Its actually really hard to catch on fire. Takes a lot of friction and pressure.
Steve S
End of a cigar while just smoldering is 750-850 degrees F...
That part made from a "flammable material" sure looks like a cigar ashtray LOL
Why superglue it the second time when you had another tormach sitting there with a vise on it?
The Metal Butcher you're not going to keep your customers long if you put vise jaw marks into their parts' final surface finish.
Why did you use that material?
Why not just use a full downcutting endmill instead of the compression mill?
I wonder what the difference is between richlite and micarta is..🤔
Machinist 72 that’s my first thought it’s basically micarta.
Same here
I'm thinking the difference may be in the type of resin used?
How about making our own with paper, flour, and water?
Richlite and Paperstone are probably the two leading products in the 'green/architectural product' category. They're widely used in countertops, exterior cladding panels, and interestingly enough, skateparks. The biggest difference is probably that they've worked hard to optimize their process and materials to score LEED points with the 'green' consumer.
Comments disabled on last vid?
Maybe it got invaded by flat earthers and moon hoaxers?
If you use a white bristle skirt, pic would have been better. :)
How is Richlite different than Phenolic ?
Phenolic is a resin that can be used with various bases like paper, glass fiber or just on its own. Richlite is the specific combinationof phenolic resin plus paper.
Richlite is specifically paper based with phenolic resin binder, Micarta was traditionally cotton or linen fabric based (originated by Westinghouse in the early 1900's), but now can range from paper to natural fibers to carbon fiber and fiberglass.
it's clearly a mold for a quadrotor drone :/
I use double sided silicon tap works great.
Juliamarie Palero
Tape with silicone adhesive? Do you use it with flood coolant by chance? Can you mention the specific brand/type that you use (and maybe where you buy it)? How does the tape behave when you mill into it? (is it gummy? does it machine away cleanly? does it smear? etc.)
I like the idea of taping parts down; it sure does seem to be a fairly universal solution with low startup cost. Effective too. It's just that putting on the two layers of tape with super glue seems like more prep than I would want to to very often, and I'm _a-scared_ of how that particular tape would stand up to coolant.
Oh, the other NYCCNC video from today shows that tape and super glue holding up to coolant just fine. Sweet!
I wonder if all the video titles really need to be exclaimed?!
That's also how he actually talk...
Антон Южаков, I think you forgot something!
But it's not Wednesday yet
Maybe John moved to Australia...
I really have come to like your channel more and more. At first you seemed like a hack, but you've grown quite a bit as a machinist over the years. Still plenty of growing left to do, but getting better all the time, heck, I'm still growing as a machinist and I've done it for 25+ years (and still love it!) One thing I have noticed over the last couple months, seems your videos have gotten shorter and shorter almost as though it's getting to be a bother keeping up with RUclips. Hope that's not the case, just an observation I've had, and maybe it's just me.
Thanks for sharing, stay on bottom ... Turnin' to the right.

I have noticed the same with the video time spans. Still very good learning and intelligent as usual.
Considering Johns skill level, the fairly simple contour / nature of this "part", it is distressing to see the level of effort required to finish what I feel should have been a cake walk for Fusion.
That is some of the worst toolpaths I have seen from this channel, the programmer wouldn't last a day in a real shop producing parts so slow.
greihawk it would take longer to completely optimize the tool path and run the single part than it would take to just run it with a slightly unoptimized tool path. Really not worth the time for a one off.
That’s the difference between prototyping and production.
Production, run time is everything. More you can get out per hour the better.
Prototyping, run time takes a back seat. When it’s only a single part that needs doing, It’s more expensive to scrap a part and do it over than it is to take the extra time and get it right the first time.
