A profile tolerance zone is an area (profile of a line) or a volume (profile of a surface) generated by offsetting each point on the nominal surface in a direction normal to the nominal surface at that point."
53. Autodesk is a leader in 3D design, engineering and entertainment software. If this figure was according to ISO, the all-around tolerance zone in the area of all corners would be rounded and not sharp. I agree, ISO should provide more clarification. If these requirements are not addressed at the design stage, lot of time is spent in design iteration when the design reaches the die caster. 00-3 Connect with Us - Quick Links for Support and Questions. It just shows which portions of the contour the all-around specification applies to. I too am confused; as CH states Y14.5.1M states in section 6.5(a) "Definition.
My reference book is Geo Tol Pro Fundamentals Workbooks by Al Neumann page 12-19. Welcome to Autodesk’s Civil 3D Forums. 2. This page has been translated for your convenience with an automatic translation service. I still like ASME standards much better than ISO, but I would prefer CZ over CF and I think we need a sphere swept profile tolerance zone too. Full B. midpoint of the axis. I think it is still viable.
Locate the AIP. Since all the tolerance zones in principle >>go to infinity<< and the workpiece have to fulfill all the tolerances, the practical result is that you get sharp corners, as I also illustrate in my book". As a thumb-rule: Coordinates should be less than 100.0000. Fixed now. 00-1 - How to use the Course Platform & Navigation. Ask the community or share your knowledge. Can't find what you're looking for?
So, do you agree that ASME definition of all-around profile fails without proper mathematical backing? Assembly level constraints need to be satisfied before the design can move downstream. Evan Janeshewski Buy $149.00 Course curriculum. Divide the TV into 12 equal parts and draw the corresponding lateral lines (i.e., generators) in FV. A. This is what I mean by saying that default ASME definition results in rounded corners as well. 16.10. Draw FV and TV as shown. How to Show offset Dimensions in Cross Section Drawings in Civil 3D. We had an e-mail discussion, and this is how I would summarize it: Please let us know here why this post is inappropriate. You just have to make your view type "exploded" and set the I was using a different explode state on the drawing than where I had defined the offset lines. OK, I repeat one more time, the picture shown in 30 Oct 13 6:51 based on 14.5.1 definition alone, without taking 14.5 into consideration. http://files.engineering.com/getfile.aspx?folder=f... http://files.engineering.com/getfile.aspx?folder=9f4baad6-6ba2-41cc-8252-17, http://files.engineering.com/getfile.aspx?folder=270fd83b-f2e3-4ed0-94a2-4b, Engineering Report - Top 10 Defect Types in Production, White Paper - Addressing Tooling and Casting Requirements at the Design Stage, White Paper - A New Approach to Design and Manufacturing Collaboration, White Paper - The Why and How of DFM Review Automation. For reference I have attached a Cross section drawing generated with Bentley Rail Track, which shows different dimensions marked in the attached drawing. Our discussion in this thread "made me" ask Mr. H.S. Several of the tooling and casting requirements of a part can be addressed at the design stage.
