Can any one help me to find Go/No Go size for plug gauge for 2way datum slot based on the drawing please?
Profile of surface tolerance by default is bi-lateral equal (half to the inside and half to the outside of the profile).
Therefore, a perfect world go gage size is an oblong shape (15 - 0.1) x (8 - 0.1) usually + a small gage tolerance.
A perfect world no-go gage (15 + 0.1 x 8 + 0.1) - a small gage tolerance.
However, there are scenario's where these gages will not detect an out of tolerance condition.
In the old days a transparency with the inner and outer boundary tolerance zones printed on was placed on a lighted surface and the as-built pert/feature verified to be within the transparency gage tolerance lines.
Tell me and I forget. Teach me and I remember. Involve me and I learn.
