    Breaking apart a Cots part

    I have a COTS (VICD) part that will have the pieces of the part used in different models/drawings. The COTS part consist of 2 weld on flanges, and a clamp that pulls the flanges together. Flange A will be welded onto weldment A, Flange B will be welded onto weldment B, and there will be a higher...

    Profile on Sheet Metal

    I plan on using profile on the cut surfaces of sheet metal parts. Does the all around for the profile apply across the bends, or do I need to specify multiple profiles going from A<-->B, C<-->D, etc. where each call-out goes from bend to bend? If I go from bend to bend, I would create a primary...

    Lathe center marks

    When specifying the center mark left on the ends of a lathe built part, should it be fully defined via GD&T, or can a simple note allowing a max diameter and max depth be specified? Thanks in advance.

    Combining Composite and Bidirectional call outs

    Is it ok to combine a Composite hole location with a Bidirectional call out? I want to allow the PLTZF to have a relatively large X movement, with a smaller Y movement, while at the same time I would like to limit the FRTZH and have it be a diametric control. I could find no examples in Y14.5...

    Material Conditions on drawings

    When specifying a material on a drawing, is the finished temper to be listed, or is the pre-machined condition listed with the temper\heat treat requirements added in? As an additional question... Do part normally get tested post heat treat, or is certification of time\temperature of the heat...

    View labeling on multi sheet drawing

    Is there a section of any ASME specification that talks about how views on multi sheet drawings should be labeled? I am not referring to cross referencing for things like sections or details, but on complicated drawings where the views may be repeated on subsequent sheets with different features...

    Parts List on Control Documents

    Can a Control Document (Source Control or VICD) have a parts list associated with them? In the case of a SOCD, if it was an assembly made my an outside source, and there are specific components the assembly was qualified with, would be ok to put them in a Parts List, or other appropriately named...

    GD&amp;T Testing version

    Hello, I was wondering if anyone knows when ASME will be updating the Certification test to the 2009 edition? I am planning on taking the test sometime soon, but am wondering if I should wait until they update the test. Is there a disadvantage of taking the test under the 1994 standard, or...

    Use of AR in Field of view

    If a part in the parts list is shown as AR, does the AR need to be shown next to the item bubble in teh Field of Drawing where a QTY normally would go? Similar question... if the QTY of an item (bolt in a pattern for example) is obvious, does the QTY need shown next to the item bubble? Thanks...

    Drawing scale call out for isometric drawings

    What is the standard for showing the scale on a drawing that has only an isometric view? Should the scale be the cadd generated scale, or should the title block be changed to show "NONE" for the scale? And for drawings that have orthographic views, and an iso off in a corner somewhere... should...

    Showing weld beads on a drawing

    In AWS 2.4, they show the weld cross section, and they will show the "symbol" next to it. The symbol picure will show no weld representation except for the leader and symbol. My question is... Is it acceptable to show the weld bead on the drawing with the weld symbol pointing at it. I am being...

    Removal of item from the BOM on a drawing face

    I am trying to determine the correct way to show the place where an item was on a BOM when it becomes revised to have an item removed from the BOM on an assembly drawing. Drawings are done in SW, so considered digital and not manual. Do you: a. put "Removed" for that item number? b. Renumber...

    Properties on multi sheet\part drawings

    Hello, I am back to using Inventor after a few years using Solidworks, and am having problems finding out how to do something in inventor, that was a simple right click and chose function in SW. This company creates weldment drawings as one file with mult-pages for the various components of...

    Aplly distance instead of force

    Hello, I am using Cosmos Professional, and I am trying to apply a distance to a beam, to get the force. Is this possible? I know how far I need to move it, and want to know the force to do it. I have been applying forces, and adjusting it, until I get the correct displacement, but it would be...

    reflow and wave soldering

    Can somebdoy explain to me the differences between re-flow solder and wave solder. Do the boards see different heat (does wave see heat only one side of board, and reflow both?) Is there a such thing as flow solder? Any help would be appreciated. Thank You

    Stress relief of BeCu

    I am trying to minimize the Bauschinger effect in a 1/4H BeCu (UNS C17200) wire, that has been formed. How would I find the time and temperature to achive this? Would the standard 600deg F for 2 hours remove the stress? If the heat treat does not remove the stress, is it possible to Stress...
