@CooperZurad @Kuu3_Mechanics Yes, similar cases are solved already, the hard part would be generating the solids / surfaces as brep for the input
English
@Kuu3_Mechanics Hey @Alex_treseder you think we could make the CAM for these? I bet these could be made with multi-axis cuts

Yea, the first thing to do with a brand new vise is to scratch the shit out of the surface ground mating face with a hard bench stone.
Precision ground flat stone? Sure!
Arkansas stone? Sure!
Bench stone? You are an animal!
TITANS of CNC MACHINING@titangilroy
Proper Vise Install 🤌

Jumps as in oscillation in tension? This is the expected behavior of using gearmotors, the side thats doing the braking will be unstable. It is analogous to pulling a cinderblock on the sidewalk with a bungee cord. The closer to direct drive the better. I don’t think its an irreconcilable problem if this is what you are running into

@amypretzel Draft inspection has been part of CAD systems for like 30+ years. AI will eat that for lunch

On my software im choosing to have a required user input for z spacing and lower guide z position so that the g code can be interpreted without correction. None of the proposed diy controllers have that correction capability built into the interpreter currently, but as you said it is a simple bit of trig so i will leave it for a future option.

@CooperZurad @Alex_treseder Normally at the plane of your table). The machine then does the math for how far your top and bottom dies are from that, so you don't worry about the location of the heads, just where the job is. Pretty easy bit of trig.

@__el__toro__ Ya i think any less center span and it would have started to be a problem but it worked fine. Probably could have gotten away with 3mm wide belts and that would have been a little better. Its an underated technique for sure
English
@Alex_treseder Nice! Long span doesn't look like it's taxing the belt much.
English
A unique aspect of belt drives are their ability to be twisted & crossed to change the direction & axis of rotation.
Not all belts can handle this & you have to be careful not to exceed design limitations of the belt, but you can solve tricky problems by using a twisted design.
Mechanical Knowledge@mechanical_4u
Modern robotic wrist joints often use timing belt differentials to achieve smooth, multi-axis movement within compact spaces. By distributing motion through synchronized belt systems, a single actuator can control multiple rotational outputs with high precision. This design reduces weight, minimizes backlash, and allows for more efficient force transmission compared to traditional gear-based systems. It is widely used in robotic arms where accuracy, responsiveness, and compactness are critical. The result is more natural, fluid motion-bringing robotic systems closer to human-like dexterity in industrial and automation applications.

@CooperZurad Currently it is called EDM Candidate Gantry 3 final (2) v12.f3z

@Alex_treseder Dude I'm so bad with names. What are you naming yours?

Aerospace CNC machining contract strategy, Tell me if I'm crazy:
Get lots of business from large aerospace prime.
Take out purchase order loan for 2% interest.
Charge large aerospace prime that 2% interest by baking it into the cost of the parts.
Win.

Good morning 🌞 What are we simulating on our cnc machines today to help re-industrialize America?
We're finalizing a keyway slot in a titanium part on one of our swiss lathes to minimize endmill stickout (and not crash into the larger diameter shoulder end of the part).
English
@stay_curious_1 @ElectronicsbyJH Scilab is the closest open source thing
English
@ElectronicsbyJH What are you using? To my knowledge there isn't a real replacement for simulink in the python ecosystem
English
Yea I need to convert this to python, I really don't want to use MATLAB/Simulink tbh
English
@bryan_johnson Cnc programming our swiss lathe machines to make parts for weapons of mass destruction with my pet chicken Persephone. Then will probably smoke a cigar and read some Lord Byron or maybe Shelley.
