What lathe?

Another tip. Don't leave G95 in the machine when you need G94. It will jack your world

Machinists don't need no stinkin' roller coasters.


We got "Rapid Z" on a new program!!!!

Hahaha! It wasn't even a Z move, I was going to make a slot cut to X+. Problem was 1444 revs at F10. I got that look on my face.

"That Look". LOL

Hey, aren't you supposed it be at work?!

You have a lathe - For "one off" you can make transfer punches in seconds. Even make the end point lightly hard with heating/oil cool if you use something like 1045. You can also make a drill guide for a small drill. Example, if you want to mark the center of a 3/8 hole, turn a piece of stock to 3/8 and drill a 1/16th hole though the center (lathe tail stock). Use machine length drills though.. not jobber. Now you can "mark" with a 1/16th drill (use the end you drilled for the contact side). Even soft steel will work well for a quite a few holes. 12L14 makes for very easy machining and drilling.

LOL ya I'm at work. Just grab a minute here and there to check the forum. I should just pick up a set of punches.

I'm like a sponge.......quietly soaking this stuff up. :msp_thumbup:

Me too.... I just wish I understood enough to learn from what most of what is being posted in this thread. Have you ever been at a point where you don't know enough to ask questions to learn what it is that you don't know??? That's me and machining...it's all Greek, spoken in a Mandarin Chinese dialect, with an Aboriginal accent.

LOL I'm barely above that level.

I wish I didn't have any pictures like that:msp_rolleyes:

Machine : Warning, rapid Z and Table move. OK?
Me : Shutup, just do as I say. [stabs finger at button impatiently]
Machine: Ok, you're the boss

BOOM

*****.... damn machine didn't tell me there was a hardened steel clamp in the shortest path from current position to origin. And... BRAND NEW FIRST USE 6 flute 1 inch M42 EM.... Never got to cut even one chip.

CNC is a miserable way to learn how expensive tooling is.

304 Stainless and Carbide is even better... everything is going just fine... then it eats a chip; from the moment you see the red glow it's all over. I HATE stainless (most) slotting without coolent.

From another life I have a window sill of shame - burnt saw pistons. Now I have a box of busted carbide to remind me what a klutz I am.

I knocked a turret disk off a turret once. Till that day, I thought that was just a tall tale.

Jeez, what kind of piss-ant cutters are you using that can't handle 10" per revolution :hmm3grin2orange:

Saw the aftermath of a HEAVY cut with a large tool with a lot of relief into a piece of brass held in a large chuck........













Brass is soft and easy to cut...... Right?

And it happens so fast......except in the flashbacks and night terrors.....

 

[FATGUY]

I canceled the work shift when I put a new tool in, forgot to put it back in. Hit cycle start. Turret moved to Z0.0 and then came straight down in X onto the chuck at 100% rapid. Sheared the 6 10mm SHCS that secured the turret disk to the turret. Scared the #### out of me.

Have you seen tapping 60RC material. Very cool.

I have not, how in the world is that done?

just googled it, saw some thread mills, but I wouldn't want to be the one...

Not thread mills. Taps.

Guy said it was PF 9.5(Pucker Factor)

You can read the catalog and watch the video.......but when you hit the start button......

He said no scream from the metal. Just 16 or so holes one after the other.

But when you think about it, I kinda makes sense. It cuts not push and tear. So no stretch and release to grab.

Like making cuts in HSS or carbide.

Searching now.....

 

[Stihl 041S]

Googled "tapping 60 RC"

Went to the PM links.

OSG and Emuge both make the taps.

I'm too stupid to post a link........sad ain't it.
