    How long to design new products?

    I'm trying to get an idea of how long it should take to design new products from other engineers. The reason for this is that I feel like it is taking my company an incredibly long time to go from design to mass production even on simple projects. My goal here is to get input from others and try...

    "Global" GD&T Standard?

    I work in a regional (U.S.) development office for a Japanese company. We primarily design parts to be sourced from local suppliers and use the ASME Y14.5M standard for most of our drawings. We also source many parts from Italy, Spain, Japan and China but most of these drawings do not use GD&T...

    Agricultural Engineering Book Recommendation?

    I am trying to locate a book that contains formulas for calculating forces on a tractor due to a tiller or plow. A colleague of mine has a agricultural engineering book written in Japanese that contains all of the formulas, but I don't want to continue asking for his help in translating the book...

    Advice on going paperless?

    beej67: I forgot to mention we have a digital whiteboard so we can project the drawing on the whiteboard, mark it up on the whiteboard and save it to a pdf file. The only problem here is that only the young guys like using the digital whiteboard.

    Advice on going paperless?

    I have been given the task of helping our department begin the process of going paperless (or nearly paperless) for engineering drawings. This is primarily driven by the fact that plotter/scanner rental, plotter supplies, and shipping drawings to our home office overseas is starting to get very...

    Position tolerance for non-piloted weld nut

    Thanks everyone. I believe the the detail view with the hole as the datum is the way to go.

    Position tolerance for non-piloted weld nut

    I am trying to determine the best way to dimension/tolerance a set of drawings where non-piloted weld nuts are involved (why we insist on using non-piloted nuts I have no idea). I have one level of drawings which details a formed plate with all the proper GD&T for placing the holes used for the...

    Material selection charts in Excel?

    I figured out a quick and dirty way to do it... 1. Plot all of the points for all of the different materials on a chart. 2. Use the outer points to draw a smooth curve around the points. 3. Delete all of the points inside the curve. 4. Use the Curve Tool under Shapes to trace the outer points...

    Material selection charts in Excel?

    I have a need to make some material selection/comparison charts similar to the one shown here: http://oregonstate.edu/instruct/me480/Lecture/W03/SelChartsgifs/SelChart2.gif I remember a piece of software from college that could do this, but I really don't think it is necessary to purchase a...

    Data management strategies

    This thread is a follow up to a thread I started last year: here I realize that I forgot to answer one of the fundamental questions that was asked: how many users? At my current job there are about 300 engineers, and there were about 1000 at my previous job. Now it has been about a year since...

    Reference Book of U.S. Drawing Standards?

    Are you referring to this manual: http://mscweb.gsfc.nasa.gov/543web/files/GSFC-X-673-64-1F.pdf If not, can you provide a link?

    Reference Book of U.S. Drawing Standards?

    This is exactly what I am looking for. We are going to get a copy of Y14.100 and possibly the other supporting standards.

    Reference Book of U.S. Drawing Standards?

    I am searching for a reference book to help get a Japanese manager (and engineer) up to speed with U.S. drawing standards and best practices. We have already given him a copy of ASME Y14.5M-2009 for understanding GD&T, but he wants a better understanding of best practices for different types of...

    Too much info in DFMEA

    It is my understanding that the primary purpose of a DFMEA is to act as a checklist of items to consider/check when designing and testing. This is the way I have always utilized a DFMEA, but my current employer wants to use it to capture design history. Because of this, our DFMEA template has...

    Master Model Rules

    @loki3000,my company designs agricultural equipment and each machine is different. Even machines in the same class can be very different in design/construction, and things are constantly evolving. Also, my company is terrible at "Kaizen" or making continual improvements to existing designs...

    Master Model Rules

    I am putting together a proposal to improve the way in which my company creates Pro/E master models for large project. At the moment, we are using the wild west approach and it has caused some serious issues with both drawing/model consistency and prototype parts. To help clean things up, I am...

    Datum holes and frame of reference

    Ok, this is sort of a follow question that I can't seem to find any good references on... I have an assembly composed of several welded plates and I would like to use the plate I used in my example (see previous attachment) as the base. At the child part level, I can attach the tolerance to the...

    Datum holes and frame of reference

    I have a question about using holes as datums and how a frame of reference is defined (see attachment). It is my understanding that holes can be used as datums even if they aren't aligned along the same line as shown in the orientation labeled "1" in my drawing (for clarification, Datum A...
