Using standard ASME Y14.5M.
So I have a drawing callout for dimension inspection 2.000". This part is, let say, its round.
How should I measure this part?
--X is having the part sitting on a surface plate, then using the height gage or CMM to measure the value. Origin value is reference to the...
For example:
The drawing callout of the part has a diameter of 10.000 +/-.005"
Using CMM to measure this part:
Diameter 10.003"
Roundness is .011".
Does anybody know how these number formulate?
I am confuse about this AVG explanation. Would like someone help to clarify.
Let say I have a cylindrical part. The diameter comes with AVG notation at side.
Does this mean that it is require to measure the diameter at least at four different sections and get the average result?
If yes, if one...
I am looking for caster, most likely to be stainless and will be used in high temperature, about 280-450C. It should handle at least 200lb per caster.
As I know most caster come with greased, or plain bearing. This specific caster should not have grease, no bronze filling.
Do you know where to...
One of the drawing has a flatness callout at cross section view as shown.
My interpretation is the flatness suppose to apply to entire surface/plane. Use the CMM to measure and obtain the flatness result by probing several points along that circular plane.
One of my colleague stated that this...
The inspection report shows the specification requirement:
Feature: Position
Specification: 12 X .125 +.002/.000 [(TruPos symbol) dia.002 (M) | A | B ]
When I perform the CMM measurement, I am not sure about the requirement of this callout:
All three holes (callout is actually a True position...
I notice that if using the "standard" GH3 to tap a plastic, the result is too tight to screw in a plastic bolt.
Is there a rule of thumbs or reference about what tolerance or callout should I made for this thread (eg. 3/4-10 UNC) such that I could turn the nut freely and not loosing too much...
How do you calculate plastic bolt strength? Looking for tensile, shear... strength.
So far the formula that was found I believe it is for metal material.

Hi,
This is related to the old post. I lost the previous attachment somehow...Arrrgh!
Please see attachment.
These two dimensions has to be reported but want to know what is consider out-of-spec or within spec:
1. Dia. 2.000" ==>UL: 2.000+.004*2 = 2.008"...
Does the Notes from the drawing have a sequence?
Meaning that the note is practice by note 1 than to note 2, note 3, etc (or a, b, c...)? Or it doesn't matter?
What do you call this? Break sharp edges? It is a round part.
Okay, if it is break sharp corner and I specify max. .010, is the final dimension be
1. Dia. 8.638" -(2X .010, consider reach to maximum)+/-.005"?
2. OR 8.638"+/-.005" will be the final dimension?
Consider the default tolerance is...
I would like to use titanium to serve in a furnace-500C.
Not sure what properties (for example, titanium) I need to know whether it is suitable to use?
For example, the thermal coefficient...
I found out that Titanium is cheaper than Hastalloy at some point.
Need help...
Do you perform sphere qualification everyday or once a week or....?
I have told that instead of performing sphere qualification-->stylus qualification, they would perform size check, such as using a gauge ring and perform a "daily check".
Not too understand the theory behind this.
I want to
1. change the original 2D drawing template to current drawing template (from company A to B, due to acquisition) and
2. Add notes to the drawing.
Okay, since I ask something regarding the drawing standard before (alter, source control), and KENAT did provide me where to refer: ASME...
I have an outsource drawing that I would like to add a part number/document, or say use our own drawing template.
As I aware that if I simply "paste" or import their drawing, might not be a good idea (ethic, IP, ...)
Assume that there is no way to get a raw file from them. The only file I...
If I have existing part drawing (not belongs to company A), and I have to make some modification. For example: adding one hole and remove/reduce the thickness.
How or what is the best way to show this modification needed in my drawing?
Do I need to show all the detail or just show what need to...
I am looking to machine a hex key (to tightened metal screw) and have to made out of plastic material.
Is there a recommendation of this material?
I am thinking of Delrin, PVDF or Polycarbonate.
