CNC knurling without a knurling tool
Ғылым және технология
Can you knurl your part on a CNC lathe without using a knurling tool? Yes you can! Here's a little trick that will help you get the job done.
Let's say you need to machine a bolt that features a knurled head. You could do it on a manual lathe or a CNC lathe using a knurling tool and you would be perfectly fine. But let's just say it's late one evening and you want to finish your project and get the part done but you realize that you don't have the knurling tool and the machine is ready to run. What do you do then?
If your machine allows you know where the rotation is, you might be able to finish your part using a simple trick.
In this video, Derrick Hogan, CNC technology instructor at North Georgia Technical College shows the trick starting from the very first step of drawing a knurl on a piece.

That's really perfect tips 👍 thank you very much
I knew you were going to use a threading cycle. It is the obvious solution. Nice job!
I like this!
Thank you sir
Please explain how do write for fanuc operating systems

new can cycle for each lead. back the start off each cycle to create the gap between leads. as he said a lot of leads will create a big start gap if you dont have the bitchen software his badass machine comes with haha. invest in a good dorian cut knurling tool, its cheaper than this machine.
Is there a way to do variable pitch knurling using this method? Such as starting tight and transitioning to a looser pattern over the span of an inch or so? All the machine has to really do is change the feed along Z at a predictable rate but of course programming that change seems tricky.
sou do Brasil esse trabalho e fantástico parabéns
I am new to 4th axis, and I would love to see a video on how to create knurling using a 4th axis rotary and a chamfer mill.
Hi sir I have the job Knurling OD 8.0 length 6.0 How to calculate the LEAD and the Multiple start. Thanks
What is software do you program? It look awesome
How to the same programming on fanuc ? Can u please help?
muito obrigado meu irmão
Hi ya. My mazak machine is in metric ( mm). What would I need to change
Hello sir, i wonder is it all measurment in inches or millimeters?
Hi sir What dia you working. How can you get 3.14 Can youexplain. ? Thanks
What if my dia od 3.5" My Multi end up 109. Now what i need to change?
tô usou códigos G32 ou 33 para fazer essa programação
trabalho com torno comando fanuc e possível acessar esses parâmetros
ja procurei e nao encontrei
Lol This is radicaly different operation than if You are using a knurling tool:)
s3 possível me da um salve
knurling is a deformation of material. This is removal of material. its more of a crossed line pattern finish. Nice progamming and tips anyway!

Except when cut knurling, then it is not deformation. As in this example as well although different tools.

@@gerritvisser Agreed! I use a cut knurl tool and this exact method to knurl harden material or long parts without support. Example, I had to put a knurl on a fairly exact diameter pin and I wanted the knurl to be to be to a consistent depth. I could have knurled, messed with tapper to get the depth correct and then turn it back to the correct OD but it was about 4 x D (just under 1" and about 4" long). With only a couple parts to make it was way easier to just cut knurl it in. I quick hand coded macro and I was done, yes it takes a long time to run (I wouldn't want to use it on a hundred parts!) but way quicker to setup for prefect depth and basically zero risk of scrapping a part. Now when this is customer supplied material and you don't have much or any extra and then this is the very best way to go in my opinion. Nothing like a double track knurl to ruin a otherwise nice part!
