Thanks for all of your answers and suggestions ... I already informed my boss to aware this problem and pls discuss to the customer. Just like you said, Peter, it concerns the products cost to reach the customer requirements.
There is no "ASME Y14.5" specified on the dwg. BTW, I'm now take a rough scan on ASME Y14.5 and there are some questions would like to ark.
In the ASME Y14.5-2009 page 100, describing about the parallelism torelance meaning. In the fig. 6.2, showing the one block sized 26.6-26.9 (this should be...
To ptruitt, the parallelism torelance is specified in the customer's drawing. It's flat bar with appx 1800 x 100 mm dimension. Quite long bar so that's why I think that it's quite difficult to achieve to requirement. The surface smoothness is also specified but only 25 --> seems that it's...
Thanks for all of your answers ... one more question pls,
As Belanger posted, the parallelism inherently includes flatness .. But as reference to the standard (jis, as ..) for the steel bar (ss400), it states that the straightness torelance is appx 2mm/metre long ... Therefore, I understand...
Hi all, I'very new in the geometrical tolerancing area, I would like to ask you
- How to measure the parallelism of the flat bar. The customer's require is 0.05 mm. The problem is this flat bar is not totally flat. my boss told me to I used the dial indicator(the bar was put on the granite...
