Good point, Frank. Safety first, last and always. That way I can keep all my ten fingered, 2 eyed freinds and associates.

Good post Frank. I haven't been injured by it, but it's scary how that rats nest can suddenly flip around, and if it doesn't foul up on the tool post it can hit you in the face. :panic:

Turning tool steel is pretty bad too, Aluminum is too soft to break properly with most tools I have used, and delrin is just one long strand. I have found that the right DOC is critical for inserts to work correctly, so, glad you confirmed that. When making long cuts with power feed (which generates the most consistent, longest swarf), I will often stop the feed every so often to break the swarf into smaller chunks. Clear that bed of curly stuff after ever pass with something that isn't attached to you.

12L14 and 1215 on the other hand make nice little chips that fall in convenient little piles, great stuff, if you can deal with it's drawbacks (price, corrosion, non weldable, poor hot strength).

Good write up, and the topic is a goodone. Maybe if you could show some hand ground tooling with, and without chip breakers. The less experianced operaters could benifit from it. :thumbsup:
 
If in a bit of a hurry and don't have or can't make a proper chip breading lathe tool, sometimes just increasing the feed will break the chip or clamp a small piece of metal to the tool right behind the cutting edge and trying different locations until it breaks the chip and doesn't jam things up.

Can't say about a lathe as not run mine yet,but I run a Mag drill at work , a bunch, drilling holes thru frame rails for parts.

Well I was playing dumb one day about two weeks back and I pulled the long string from the bit without gloves on , and yep cut straight thru the skin all layers right at my left thumb.

So I can appreciate what you say about about those chips.
:angry:
And this is just plate steel used for trailer frames.

Well said on a very important subject. I've preached chip hooks for years, every machinist should have one before even making a first cut on a any machine that can make stringy chips. I've seen too many cuts from people pulling chips barehanded, and even with gloves.
