Please read and make suggestion- Metal Cutting Thread(s)
I personally find it *incredibly* valuable to learn from more seasoned machinists (or us home shop guys when we get lucky ) how to make pretty/accurate cut specific metals, and at least successfully cut challenging ones.
I am often dying for this info when about to put cutter to metal on the lathe or mill- and at those times it requires a lot of digging through posts to find tidbits where and there... OR, bugging everyone with "how do I cut this" when people have already thoughtfully and carefully posted advice already.
My thinking is, if ANYONE finds info useful or interesting, **even if they are not the original poster**, they should copy and paste that post to the proper thread. Maybe even start the post with the name of the metal, like "12L14 Steel".
If the name of the original poster is appropriate to post, it should be included, unless that person does not want "credit" or "blame"
We would would want as much info as possible, but ANY info would help- at least the basics like-
- depth of cut,
- Feed - like feed-gearbox setting (to the best of knowledge)?
- RPM/work diameter (effectively SFM)
- type of cutter... (Rake, angles if known)
- ** REALLY great to include a pic of the cutter (especially if HSS ground) and pic of the finished cut, bad lighting or not!
- etc...
I hope this thread has some legs- I am putting it in "Metal Finishing".
Sorry to put you on the spot here Dave , but I am talking about posts like this:
CaptDave posted to Shawn's 4-Jaw thread:
"12L14 is generally used in screw machine products, hardware and Fastners. We use it for special hardware we build and it machines beautiful. If your turning it use a sharp high positive inserts and for finishing, use a DOC that is minimum of 2X your tool nose radius. It really likes to be cut hard and fast."
If we could keep this thread going, couldn't we search out that information specifically? Or should we start a thread for each metal?
What do you guys think?
