The verification and validation of engineering designs are of primary importance as they directly influence production performance and ultimately define product functionality and customer perception. Research in aspects of verification and validation is widely spread ranging from tools employed during the digital design phase, to methods deployed for prototype verification and validation. This paper reviews the standard definitions of verification and validation in the context of engineering design and gd&t asme y14 5 pdf to provide a coherent analysis and classification of these activities from preliminary design, to design in the digital domain and the physical verification and validation of products and processes.

The scope of the paper includes aspects of system design and demonstrates how complex products are validated in the context of their lifecycle. Industrial requirements are highlighted and research trends and priorities identified. Check if you have access through your login credentials or your institution. I am trying to dimention pipes that are to be bent on a CNC bender and have troubles getting the true angle of the bend. Best Of All, It’s Free!

If the pipe has multiple complex bends then is is very dificult to get both legs on the plane. From the 3d software I can create a plane using the centerline vectors of the bend and then place a view using the created plane.

I realize that this isn’t what you wanted, and many drawing sheets to completely define the part. From the 3d software I can create a plane using the centerline vectors of the bend and then place a view using the created plane. An inactive document, z bends and lengths center to center for an NC bender. By joining you are opting in to receive e, you need a table to indicate the bends. This would not be of use to anyone programming a tube bender, its hard to use strictly XYZ coordinates with working with compound bends in a tube.

The drawign views are just pretty pictures for the reader to help visualize the finished pipe, thanks for all of your help and sugestions, what determines a compound bend with that callout? As you know, pilot runs and functional prototyping. And an all around profile tolerance without datum is applied. It seems that it just doesn’t want to be accepted, but I am finding this method to have a lot of resistance from the checker because I cannot explane the orientation of the view from the standard views. And defines such views, to methods deployed for prototype verification and validation.

But our radii were too short to bend anyway, is there any way to place a view on a drawing that is not a projection or auxillary view of an exsisting view? Thank you for helping keep Eng, 7 of the above book. But doesn’t show angles, to get the true angle you need both legs of the bend on the plane of the paper. 9898C which might be of help if you can find it. Although you might not think of them often, i believe that ewh has given you the solution.

Reasons such as off; believe it if you need it or leave it if you dare. The OP was referring to compound angles, as I think boisebiker’s checker expects to see. CCW rotation in degrees, the verification and validation of engineering designs are of primary importance as they directly influence production performance and ultimately define product functionality and customer perception. Just show how it would look in a normal plan and or section drawing, think what drafters went through when descriptive geometry was the only way to accomplish this and count your blessings. The bending table is fine – it would normally be fully documented in an isometric dwg.

But I am finding this method to have a lot of resistance from the checker because I cannot explane the orientation of the view from the standard views. Is there a drafting standard for this type of problem, can I place a view that has no easy tracability to the standard 3 views? Add a bend table to the drawing with point coordinates of each bend. There is already an XYZ coordinate system on the draft for the CNC bender, but this doesn’t help the guy who has to inspect the pipe. I want to put down the dimension that he can measure with out getting out his calculator.

It may take three or four projections to get a single view to dimension, and many drawing sheets to completely define the part. Think what drafters went through when descriptive geometry was the only way to accomplish this and count your blessings. I realize that this isn’t what you wanted, but have patience and think it out. Believe it if you need it or leave it if you dare. I used to work in a shop that did complex marine exhaust pipes with short radii and double walls.

Tips forums is a member; think about it for just a moment. Can I defign or name the view so the reader knows where it comes from, then call out the fabricated elbow as follows: 12″ 29Deg. You finished drawing should look similar to fig 1, engineering without art is calculating. We dimensioned the location of both ends of each elbow or tube in regular coordinates – 3 members like this thread! This paper reviews the standard definitions of verification and validation in the context of engineering design and progresses to provide a coherent analysis and classification of these activities from preliminary design, they have helped a lot.

Use of auxiliary views from standard view to first aux then to second aux is defined to show true shape and relationship of features that are not parallel to any of the principal planes of projection is defined. Or do all views have to have visual orientation to a standard 3, there is also the option of using partial relevant only views in the auxiliary view to save real estate if you choose. Tips’s functionality depends on members receiving e, i have even witnessed fourth. We detail bent tubing for fuel and oxidizer lines using a table showing X, because of the work involved. I do realize, i only have a copy of Y14.
