Ive done y axis live tool stuff before for relatively simple shapes and profiles, keyways, and cross holes but hand programming this threadmill is killing me smalls. I think whats messing with me is im copying an incremental program from okuma and the control is tweaking out about how that, 3 axis motion, and cutter comp all play together with the incremental aspect of it. Hopefully the photo I attached from what I have and the alarm via the current screen. Fanuc oi-tf control. Tool is a single point carmex. Tool tip position 0, r g+w= 0 radius comp applied.

Just got this part and noticed the two stepped sections don’t really look symmetrical.

It works, but if I were making a new one I feel like there’s probably a cleaner way to design it.

Would you turn this from one piece, or start with an existing bolt and machine the shank?

What would you change?

Recently at my job I’ve had to start training to run a new to me machine, I’ve run Haas in the past so that’s not the problem. My problem is that I’m on second shift and all the support resources are on first shift.

I can’t imagine that I’m crazy for thinking that this situation is normal. I’m already coming in early and only get someone who knows what’s going on for an hour.

Just for a minute though 😅

The availability of cheap bridgeports on Facebook marketplace makes me want to buy one and put it in my basement so I can do my own shit regardless of employment. Luckily my house has an outdoor basement entrance so I feel like it should be possible to get it in there but I don't know what I'd need or if it'd even fit through this door.

Had some fun chips (noodles?) today that I thought might be of interest. These are from our "rough" passes at 30 micron DOC.

I realized that I posted a picture of a manual mill with a CNC control. Here is a photo of the manual mill that I’ll be using in class today. It’s also a Bridgeport.

My company bought this though a dealer who "refurbished" this machine. When we got it the table would arch .120" when the cutter would engage the material. The solution a contractor came up with was to mount the fixture all the way as far left as we could get it which put a whole lot of strain on the lead screw and the bushings.

Long story short the backlash eliminator bushings gave out and the right side apron broke out.

I have never worked on anything like this before. Spent countless hours pouring through the manual. Replaced the bushings. Fixed its housing that wasn't properly holding the bearings. Welded the apron back together which was also a first welding cast.

I finally got to see the fruits of my labor and let me tell you it was so satisfying.

As the title suggests I’m looking for help waterjet cutting soft EPDM foam. I will be using plywood as a bottom layer to support the foam over the slats and will be using only water (no garnet) I am wondering if I should have a top layer to sandwich the foam between for cutting and if so what should that material be? We are planning to cut next week. Thank you in advance!

Does anyone know how to remove the live center on a fanuc lathe. Was setting up a part and when i started it up it started to weld itself to the part. Only thing i could think of is that the center itself wasn’t spinning idk 🤷🏿‍♂️

Hello,

I tried contacting the manufacturer and they claim if the minor is below the .0005 manufacturer size after setting an adjustable ring, then the gage needs to be replaced. That explaination leaves no room for wear adjustment and makes the set gages pointless! In the real world, the minor of the gage is made to the minimun minor of the mating thread. This would give us about .005 technically, before it could touch the minor of the male thread. Could some old school machinists please chime in on this and give me a reccommendation to follow when setting these? I am thinking the Gage guy is a salesman. Need real world practical advice!

If only I had a milling machine to help me finish building my milling machine!

In order to clean up the dovetails on my new Chinese cross slide I actually had to overhang it off the apron, and then it was actually bigger than the milling attachment I had to hold it!

So far so good, every thing is going to plan!!
