Fig 1-30 quick understanding
- Thread starter gabimo
- Start date
I guess we could be charitable to the ASME committee and remind ourselves that the figures in the standard are not complete -- they only illustrate a specific point. It seems that Figure 1-30 is emphasizing the specific point from paragraph 1.8.4, not paragraph 1.8.2.

mkcski,
I agree with you about the tangency.
1.8.2.1 also states:"Where a dimension is given to the center of a radius, a small cross is drawn at the center." ..........
"Where location of the center is unimportant, the drawing must clearly show that the arc location is controlled by other dimensioned features such as tangent surfaces."
Fig 1-30 does not have the radii centers located nor the tangency implied so I am not sure why the two small crosses are shown or will be more "correct" way to show the picture WITHOUT those two small crosses.
Or someone will argue that "in the real word" the distance between the crosses must be shown.

gabimot,
In ASME Y14.5-2009 Fig. 1-30, the small crosses at the radius centers are shown coincident with the horizontal center line of the slot width. It could be argued that they are serving to indicate an implied zero dimension for the relative vertical location.
