    Implementing Lean Concepts in n Engineering Environment

    I think your key question is to find a path for this project. Probably best to get some "outside" advice on setting this route, but not a high priced consultant. You probably have another department in your company struggling with the same objective. Say "Accounting" is going through the...

    Shaft material for bearing application

    I would agree with Terry, I think the key question is that if the inner race is experiencing reversing or rotating load relative to the shaft, then a free floating inner race with clearance is the root issue. It is difficult to guess the best mounting option without understanding the entire...

    On-line training recommendations?

    True, for V20 they only have three courses to date, but this should be enough to get me started. This Bundle includes all the V19 courses, which I figure should be ok for a mature product. Thanks again, ERT

    On-line training recommendations?

    Kyle, thanks for your pointer. This will be helpful when we move to ST. CorBL - thanks for this link. I still do not understand why my search for "training" did not find any threads in the last 14 months. Regards, ERT

    On-line training recommendations?

    Hi All, Can anyone recommend an on-line training course for SolidEdge V20 Classic? If anyone knows of a free course that would be great; but my experience is that you rarely get more than you pay for. I am looking for a good fundamentals course for a machine design user - part modelling...

    Hole Command - Custom.xml download?

    Hi All, I am trying to setup a new system with standard hole/counterbore/countersink/threads favourites; both inch and metric. Does anyone know of a good source to download a "custom.xml" file that would have common hole sizes for automation machine design? Regards, ERT

    What is the least expensive distance measurement device?

    Thanks to all for your input. Yes, we have tried the floor money approach, not really practical for us as we have over 100 of these systems. We are currently trialing the string pot idea. We actually went with a low resolution encoder on a wire drawn unit. Regards, ERT

    What is the least expensive distance measurement device?

    GregL, Is that RS Electronics, or someone else? ERT

    What is the least expensive distance measurement device?

    GregL, Yes good questions, say 5 year life. Which would mean a life criteria of only 1000 strokes. And yes, I only need the accuracy on the slow stroke. I have had second thoughts of how this device could be arranged - I think the slow stroke when the measuring occurs is better suited to the...

    What is the least expensive distance measurement device?

    Mike - thanks for this, I had heard of a linear pot, but the cable pot is a new idea to me. Pat - thanks as well, but I do need a measurement system along the entire stroke. Within the discrete realm, I had thought of using several proximity sensors or photoeyes on flags staggered at the ±1/8...

    What is the least expensive distance measurement device?

    Hi all, I am designing a machine that has a pneumatic cylinder and ram system. I want to measure the cylinder stroke with a system that is relatively inexpensive ($200~$300 would be great). The stroke is 30 inches, and it cycles only about once a day. It moves very slowly in extend, and...

    Sensitive Pressure switch/transducer with high burst pressure?

    dcasto, Good point, except that the purpose of the relief valve is to allow depressurization of the service, it is not meant as a safety feature. So, my measurements indicate that the relief valve line sizing and length creates spikes of 500 to 1500 psi (hard to measure). I figure it would be...

    Sensitive Pressure switch/transducer with high burst pressure?

    Hi pump fans, I have an application where I am using a PD pump to pump a viscous liquid/paste at 3000 to 5000 psi out of a drum. I want to put a pressure switch or transducer in the system to monitor the pressure in the drum to see what is going on at the suction end of the pump. The only...

    Options to avoid cylinder drift caused by center blocked valve leakage

    Hi all, Our plant standard for pneumatic valving is to switch to the center position on a center blocked valve for any pneumatic actuation that is exposed to an operator. We program the machine to hold the "clamp" position as long as the operator has booth of the anti-tie down buttons pressed...

    Entrained air removal from viscous paste in drum or pail

    Thanks for all your input. D-Mike, can you suggest a manufacturer? Two options would be great. ERT

    Entrained air removal from viscous paste in drum or pail

    Hi, I have an application where we pump a viscous adhesive paste from drums into other drums or pails. We then put the drums/pails under dispensing pumps at the robotic dispense line. It is essential that there be no air in the bulk material, because it causes problems for the adhesive...

    ISO vs ANSI Roller Chain & Sprockets

    Thanks Russell. I have since discovered that Martin Sprocket http://www.martinsprocket.com/ makes ANSI and ISO sprockets in North America, so availability is not a problem. Regards, ERT

    ISO vs ANSI Roller Chain & Sprockets

    Hi all, Does anyone understand what the differences are between ISO and ANSI roller chain and sprocket dimensions? If so, can you comment on running ISO chain on ANSI sprockets? Regards, ERT

    Need quick drying paint suggestions

    Hi all, Thanks for your input. Yes, ink is a viable alternative. The people at www.efd-inc.com and Dykem have been helpful. On the quick drying paint option, it appears that UV curing a UV sensitive paint is the way to go. Regards, ERT
