    Standard for keys and keyways/keyseats design (Aircraft)

    Hi all, Is there an accepted standard (e.g. MIL, MS etc.) for designing keys and keyways/keyseats for aircraft components? I need for designing a rectangular key with one end rounded. Not sure if its relevant but the key material has to be stainless steel. Google and various LLM's didn't help...

    Standard for keys and keyways/keyseats design (Aircraft)

    The traffic on that forum is practically dead compared to this one, so I figured bigger traffic beats a specialized forum. Why is that? 😅 It's the first time I hear something negative against. If they are evil, what are the "better" alternatives?

    Spring Modeling Help (Solidworks)

    Hi all, Trying to model a spring with both ends closed-&-ground, using the Helix tool and defined by 'Pitch and Revolution'. I just can't figure this tool out, how the F the parameters in the table work/linked. various AI chats didn't help, neither google/youtube, nor the laughable "help" of...

    Any Good Quality Document - MS33649C

    Hi all, Looking for a good quality datasheet for the MS33649C; female ports. I have one (and found online the same quality) but it looks like crap and I'm not entirely sure about some geometric details. Thanks! SD

    Parametric Spur-Gear CAD file?

    Hi all, In the middle of designing a gear-pump, with 12 teeth per gear. Because of the number of teeth, I need to implement a profile-shift. Can some help with a parametric CAD model of a spur-gear? Thanks, SD

    3D Printing of Functional Aerospace Prototypes?

    Do you bay any chance remember the maker and model of the printers? Can you tell if there were limitations regarding the material type, meaning the printer accepted only one type of alloy, or 6061 could be used?

    3D Printing of Functional Aerospace Prototypes?

    For the printing, did you use 3rd party suppliers or bought your own 3DP setup?

    3D Printing of Functional Aerospace Prototypes?

    Can you elaborate a bit..? How the cost of 3DP compared to traditional manufacturing? Did you set-up a printing line at your place or used 3rd party suppliers? How did you manage to keep the critical geometric and dimensional features (e.g. flatness, parallelism, tight tolerances etc.), the...

    3D Printing of Functional Aerospace Prototypes?

    Hi all, As the title suggests, I'm exploring the feasibility of manufacturing advanced prototypes (pre-production, for "ground" testing purposes only) of aerospace industry components using 3D printing technology. The company I work for produces aerospace components (R&D, reverse engineering...

    Suggestion: Laser Welding System for Thin Stainless Steel & Non-Linear Weld Paths?

    Hi all, Just to clarify that at the moment I'm just exploring the options in general, to see if there is any viability in this at all. At my workplace there is a need to weld thin pieces of sheet metal (0.2-0.5mm thickness; CRES 321, CRES 347) along a non-linear weld-path. At the moment the...

    Hole Wizard - UNC STI Tapped Hole?

    Hi all, It might be staring right at me and I just don't see it, but.. Is there a way to add tapped holes for UNC STI (for inserts) using the hole-wizard? The idea is to get the "automation" when dimensioning the feature during the creation of a technical drawing, so all the info about the hole...

    Configuring Digital I/O Inputs on EPOS4 Compact 50/5 for Basic BLDC Motor Control?

    Regarding the AI, yes but briefly, just to get a sense if this rout has any practical advises, but this wasn't that helpful. Regarding the communication, the controller can be programed for specific functionality using a dedicated software (EPOS Studio). But the question is how (if this is...
