I see. If I apply a Datum (D) to the width of the oval this will produce the datum plane as of the CL of oval? or should I use the one side of the parallel rib including 3 target datums?
Thanks Peter.
Will look into the horizontal text and I think I will also denote datum B in a side view for clarity. Datum A,B & C are not removed by machining but datum D is. To get a datum plane similar to D is it legit to use the oval CL instead?
New drawing attached (the drawing will be legible when zoomed at actual pixel level).
Standard is to ASM Y14.5M-1999.
The part is a cast inlet cone for a light vehicle exhaust system.
Important features are oval outlet, round inlet and 3x protrusions.
I'm not to sure how tightly toleranced...
My GD&T is not to hot as learning! See drawing attached of a simple pre machined casting. Please add comment on my Datum choices and tolerance features - do they make sense? any comments are welcomed. Thanks
It’s for a technical manual of sorts!! So it needs to look technical and pretty. I have tried to screen capture in Catia and copied screen ect…but the color quality/shade changes(even set at high res, so not matching the filled sections I have on the drawing. Must be a way as when you are...
I would like to be able to bring in fully shaded (as per model view) Iso views into my drawings, but cant get it to shade. I have looked through my general options, view properties and enabled 3D spec/colors with no luck. Note that I am unable to change my xml standards!
Thanks
I’m looking to get painted some small plastic brief case shells. They are vac formed from 3mm ABS sheets.
I was looking into pre colored sheet material but because I want the wide range of colors/effects I’m going for a painting solution.
With painting I’m worried that they will scratch, flake...
I have contacted extruders, plastic wholesales and visited Vac formers. As explained my low quantities are the issue and I just can’t get hold of what I want. As suggested it seems as I will have to paint. A Vac former has suggested painting the outer surface of 3mm high impact abs as they...
Thanks Demon3
Started looking into ASA – they make car roof boxes from this but it is co extruded with ABS to give it its impact strength.
My case is only small 500mmx400mm – do you think I would need the ABS substrate for the impact strength?
Hopefully I can get ASA or ABS/ASA in a variety...
I have contacted many suppliers but due to the low volume and non standard coloures needed its a no go at the moment!
Started looking into paint films - thanks HDS. Do you think I (supplier) could vac form a film in between to clear sheets? Is this the norm? The shape is fairly simple with no...
Thanks,
Kydex seem to have a good selection of ABS with decorative layers, and a distribution channel in China so I’m going to contact them.
I am going to try and find a supplier who produced capped abs in a metallic range (if they exist). My initial quantities will be to low (1 tonne) to...
I have attached a picture of what I want - its almost metalic.http://files.engineering.com/getfile.aspx?folder=79107216-d0c5-4ca9-b3fe-26ad68cf730f&file=blue.jpg
Hi all,
I am looking for 2.5mm abs or polycarbonate sheet that will be vacuum formed to produce a luggage hard shell. This will be formed in China and I have been contacting via email my requirements to the vac formers. The trouble is that the Chinese do not understand my requirement for a high...
I do appreciate the wide variety of variables but I think you guys have answered my question. I only need to acquire 0.2mm in critical area so sound like I’m not asking too much, so the drawings won’t raise unnecessary alarm bells and increased cost. I will be talking to suppliers after getting...
