Very thought provoking! The good news is that I will not be anywhere near an earthquake zone and do not need to factor that into the design. I have also already contacted a PE to esure that the design is safe.
That being said, I have been in contact with my client and they will handle all of...
Thank you for taking the time to respond to this thread. I love reading this forum and always find its contents useful. Now that I have you thinking about it I can get a little deeper into the design. Trust me, if I had anything to do with it, the entire design would have four columns with a...
UcfSE,
I appreciate your straight forward response. This may be a little bit above my ME training. I always find it more beneficial to my growth as a professional to first attempt the design before getting it verified or changed by Professional assistance. I do plan on hiring this out for...
I am a mechanical engineer that is in the process of designing a raised mezzanine structure. The mez is approx. 340" (x axis) x 160" (y axis) and 8' off of the concrete flooring of the plant. Typically I would have no problem with these spec but my customer is requiring only two columns to...
I think I need to use the PLC. It will be automating the drilling process with all of the other components. I need it to control pneumatic cylinders and have the ability to be switch from one part to another for different drilling locations. This being the case, would I want to get a simple...
I'm looking to spend less than $250 if that is possible for this area of the drilling machine. The stepper will only be used to posistion material. I will be drilling 2" and smaller aluminum square tube. The motor will only need to overcome part/machine inertia and hold it position durring...
Thanks for your Time. I completed all of the dynamic calculations to determine the proper Stepper Motor size found one that would fit my application, found a small driver for the motor and then hit a huge snag right before I purchased the items. I was planning on using a mitsubishi FXo PLC to...
I have a 24 V DC 0.18 A Step-Syn Step motor(Sanyo Denki) out of an old IBM computer. I would like to use this step motor to drive a lead screw in a drilling machine I am designing. There are 5 leads coming out of the Step motor: Black, Red, Orange, Blue, and Yellow. Just guessing I believe...
metengr,
Thank you very much for your time. I do perform destructive testing here, however I do not do any nondestructive testing and was not familiar with the NDT solvents. I looked up that website and it turns out that Magna Corp. is right in my backyard. They are going to send me a...
Hello,
I am a young mechanical at a aluminum fab shop. We weld most of our connections and I have been having a serious problem with weld contamination from of punch fliud. I realize the importance of cleanliness for aluminum welding but it is essential that I use some type of cutting fluid...
Like BobK98 I am an even younger engineer (mechanical '02) that was only exposed to beam theory in school. I am now faced with a critical design issue that may need plate theory to be correctly modeled. I don't even know where to begin; I have sifted through Kirchoff and Timoshenko and don't...
Thanks corypad,
That’s what I thought needed to happen, it is just going to slow down my assembly time and add cost. I imagine I will have to drill though the steel spacers to create a firm joint around the entire fastener. Would it still fail if could place the screw as close to the spacer...
I am involved with the design of steel and aluminum platform and have a fastener issue. I need to attach Al 5056 decking to a common a36 steel frame. I have a special aluminum extrusion that allows a piece of flat steel to be wedged into its sides and welded down to the steel frame. The...
I appreciate the help. I used 0.6 * Su as a starting point but the pin is going to be safety critical so I am going to run a simple test to verify, and then probably use a fair factor of safety. Thank you for your time.
