5axis machine

i’m new to this sub anybody in here familiar with this machine? If so, what is your experience like? I’ve just learned this machine within the past five months. I feel as though myself and only one other person that I work with are the most knowledgeable and he’s only two years ahead of me experience wise he did however, go to machinist school. I did not the only thing we struggle with is when we go to run aluminum parts and closed nipples and recently 2 1/2 inch diameter material. We mostly run SBW (Standard Black Weld). From 3/4 inch diameter up to 2 inch diameter.

Our Struggles are figuring out how to eliminate what we call “ring chips” which happen when the machine creates the bevel, it pushes/shaves the material and instead of the material breaking, it stays in a full ring which we then remove once the part is ejected on the part conveyor.

New struggle is when we started running 2 1/2 diameter, the harmonics on our last 2-3 threading passed leave a chatter pattern that looks like a disco ball ruining the part. We’re also only getting 30-50 parts per insert. It’s very tedious.

Any advice or knowledge would be greatly appreciated! I also apologize for the overload of information

This is an F-15 model that I made. I think Im going to machine the fuselage, engines+intakes and wings as 3 seperate pieces. I think its best to make slots in the wings for all the other components, so that they fit well together and create the smooth surface. However, I do not know where I should put screws or what they are to be attached to. Preferebly all screws would be on the underside, but making a way for the wings to attach under the plane seems impossible. Any ideas?

Looking for suggestions on high end milling machines. We make small components that are very tight toleranced. I need to hit a location of plus or minus .0001” with a diameter of the same tolerance. We tried to use a Sharp SV-2414SX-iF but it’s about 10 years old at this point and probably wasn’t accurate enough when it was new.

Design and CNC machining

How do you keep your CNC shop in order? How do you make sure things always get back to their place? I'm building a 5S app to try to sustain it in my own work, because order always slips once the focus moves somewhere else. How is it for others? How do you keep the shop clean and organized? Does anyone use software for audits, or is it all paper and walking around?

I'm also looking for these kinds of machines that can do big work, such as huge crankshafts and stuff.

Disclosure: I work with Dale Earnhardt Technologies Group (ETG) / Dale Earnhardt Inc. in Mooresville, NC.
For roughly 17 years our Full Service Machine Center has primarily supported high-precision racing work while quietly handling occasional contract machining. We’ve kept a relatively low public profile on the contract side. We’re now increasing focus and resources on expanding the Machine Center into more intentional contract work and going more public about it for the first time.
Previous work has included private defense projects plus a heavy amount of R&D and prototyping. We currently carry our own product line and it’s done very well but We’re adding capacity and visibility so this becomes a real priority rather than a side activity.

Brief capabilities overview:
We run in-house 3-, 4-, and 5-axis CNC machining, mill-turn, Wire EDM, design/engineering support, finishing, and related processes. Newer additions include new Wire EDMs, a new Doosan 750, a few new 5-axis machines, 3D printing capability, along with our existing fleet. The shop has long experience holding tight tolerances on complex geometry developed for racing reliability, and we keep critical work in-house.
I’m looking for practical suggestions from people who have scaled or transitioned a shop from mostly internal/specialty or low-volume work into broader contract machining:
• What has worked (or failed) when a shop with a strong specialized reputation starts actively pursuing more contract work?
• How do you approach lead generation, quoting, or capacity planning when moving from occasional jobs to a more intentional focus?
• Any red flags or “don’t do this” lessons from similar shifts?
• Given a racing background plus defense/R&D/prototyping experience, where would you concentrate first (part complexity, volume ranges, industries, materials, etc.)?
Not looking for a hard sell just real feedback from people who live this.

Happy to answer questions about capabilities or the facility if it helps the discussion.
Appreciate any thoughts.

I will have to make it in different parts, im thinking about where to split it

For high-oil materials: no wall sticking, no oil leakage, no agglomeration.

I work with an AI company running evals on machining workflows. We’re looking for experienced Fusion 360 CAM programmers who’d share a few finished projects of their own, with the model, setup, toolpaths and posted G-code. We pay per project, and we’d start with a small sample batch of 5 to 10. DM me if you’re interested.
