I have an issue with my tool. Application material SS304L. Operation - Vane slitting; our carbide end mill - trial and pilot lot successful. Initial two lots of tools were performing with no issues. Later, we found chattering marks on the material. All the tools were from the same batch. We tried with lot many changes in the operation; but nothing worked out. Could you suggest me a solution?
Awesome video, I especially liked the recap at the end of the video. If I may request a topic, tool coatings and how it wears. Oxidation/diffusion/etc. Curious if AlTiSiN is really that much better vs AlTiN. Thanks Don.
Don... Another informative session... And fun too...! Carbon of material always angry on the tool.. And tool wins the war with it's coating.. Great explanation... And whatever may be the Rockwell hardness vallue, u being a CTC, always rock the session as usual!! Thanks for sharing the knowledge 😊
Great content! I knew in general run slower on harder materials but had no idea about the carbon content factor.... that an annealed high-carbon material, though soft, still need to run slow, and remember it is abrasive Question... does carbon content tie into work hardening? I would assume so based on this. Last, yes I'd proudly wear that T-shirt! Thanks for everything you've taught me so far.
Hey Joshua thanks for watching. There are a lot of factors that attribute to Work hardening... Believe it or not they kind of call it Work Strengthening. It actually can be used to help make your components stronger,, But I digress! Higher carbon does contribute to more work hardening along with other elements, ( Chromium is another) One of the factors is the difference from Tensile strength to Yield Strength. Usually the greater that distance the greater the ability to work harden.. Best way to combat some of this is to not Baby your tools. When a material work hardens make sure you take a good chip load!! Get underneath that work hardened layer. You will find that tool life goes up with a bigger chip. We will get your info for that shirt sir.. Thanks again for participating! CTC
Wanna ask if you could elaborate on best practices and tooling selections when milling thicker A36 laser cut plate like 3/4in and above with a bit of a rough outer shell. Also gimmi a t-shirt too :)
Good Ol A36.. First of all A36 is low carbon hot rolled material. It usually comes with a lot of Scale on the outside and kind of looks like crap when you get it. Makes the machine a mess with carbon scale on the outside. That being said there is a method of taking a Conventional cut on the outside flame cut vs your traditional Climb pass. The point is there is good clean material under the flame cut and the scale. If you conventional cut then every subset tooth should be in the fresh stuff. So try a conventional cut on the outside ( Making sure to get to clean material on first pass) and you should see a bump in tool life... Bonus info.. A fine tooth Knuckle rougher works well on flame cut material and scale... Hope this helps and we will get your info for that shirt!!
Another great video!
Highly productive session.
Thanks for watching. Ctc
Great stuff. Taxes and spring passes
Excellent job, thanks
Thanks Don!! How do I get my teeshirt?

I just found this channel. Fantastic content! I love your energy.
Thanks for the nice comment. Please share so others can enjoy. CTC

Tool coatings is in the queue!! Thanks for watching.

I want a T-shirt!
Sean please give me an email I can contact you for a shirt. Thanks CTC
Gimme a t-shirt!
Please give me a good email to contact you for a shirt.
