    Creo Distributed Services Manager.....................................

    Sadly, software is one of the most jargon-intensive, obfuscated products I've ever had the 'privilege' of shopping for. I've been using PTC products for 25 years and when I go on their website (or most any corporate software website) I mostly cannot decipher what things do or how they could...

    RPM range for air duster/blower

    And freshly fallen. Fallen snow cross-links and solidifies with time and/or melt cycles. I agree that leaf blowers can work and I thank my deity that none of my current neighbors use one. What a tremendously noisy and inefficient tool.

    Force req'd for connection to fail

    This is a subtly complicated assembly. First, can your flip the bracket to hang? At least then the bending moment will push the bracket into the PTR. The gap makes it much harder to accurately calculate a capacity. Some will define failure of a bolted component as the moment when the load...

    Creo Distributed Services Manager.....................................

    It's a software tool that allows computers on a local network with Creo products installed to perform work for a centrally managed resource. So CPU- and memory-intensive activities such as FEA runs or executing fully automated Creo models can be handled without a dedicated mega-server. Perhaps...

    PTC Creo Parametric vs PTC Creo Generative design.......

    Creo Parametric is PTC's core 3d parametric modeling and drafting software, formerly Pro/ENGINEER. Creo Generative is an optional module within Creo Parametric. Generative lets you design a component (e.g. a bracket with mounting point at each end) and then specify mechanical loads and then...

    Bushing Contact

    Presumably the bushing is press fit with adequate interference / contact pressure that there can be no slippage or fretting between the bushing and part in operation. That means the contact interface should behave as bonded. Whether the stresses resulting from the contact pressure are...

    Learning PTC Creo..........

    I might be late to this thread but I was an instructor for CADQuest, who for years published the broadest group of Creo tutorial books out there and I think they were quite good quality too. PTC hated us because we made their training resources look bad. I think you can learn a lot about Creo...

    Fan vibration and its effect on fasteners

    If your equipment needs to be CE self-certified, such guards must be fastened so that tools are required. They don't want operators to just casually remove them for their convenience.

    How can such a part be made from steel?

    "Steel" means not very much. If it needs to be maraging or heat treated alloy steel that could be quite messy. If it's a ductile low carbon steel like A-36 then the spinning and forming options could make sense. I think the overall strategy is to take a piece of cut plate and form the...

    VFD Configuration

    If the motor vendor has an order in hand they can generally provide the nameplate data immediately.

    Strength of laminated steel plates vs. solid section

    There are shops that will roll/weld about any reasonable plate thickness into about any reasonable diameter. There's a big one in Texas that specializes in that and one of my vendors uses them regularly for even very small quantities.

    Does a bolt in a threaded hole have a preload or clamping force? If not, what is keeping the joint together.

    The bolt is definitely under preload, otherwise there would not be any torque when it's tightened and it wouldn't hold anything securely. Think of the threaded hole in the mating plate as being a nut. That's how it behaves. It doesn't care if it's clamping one, two, or more members in...

    Belt Driven Industrial Robotic Concept

    I was going to suggest the Gates power design software, so I'm glad you're already trying it. In my industry we use gearing or synchronous belts (Gates GT4, Contitech (Goodyear Eagle) herringbone). Our task is speed reduction / torque increase not robotic movement. Gears are better for high...
