The length (horizontal dimension of the slot): This has a feature size tolerance of ±0.5 mm and a position tolerance of 0.8 mm at MMC with respect to datum reference frame ABC. Following the logic of using slots, this feature has the highest tolerances. The 4 hole pattern: The holes in the pattern have a feature size tolerance of ±0.1 mm.
What is the best way to call out a slot? I have used basic dimension to reference the true center of the slot from 2 perpendicular datums. Then I called out the width of the slot and the height (the length from one tangent line off the full radius to the other tangent line) using standard dimension with tolerances. Then I called out the '2 X Full Radius' and also had a positioning block calling out diametric position of the center of the freature. Does this sound correct?
- Electrical components adjacent to the slot, and the MicroSaver product should never be in contact with any electrical components. All indicated dimensions are in millimeters. Indicated volume to be left free and clear of obstructions. Cable ring can rotate 360 degrees with respect to hole. Kensington Technology Group 333 Twin Dolphin.
- Just wondering how you are dimensioning slots on your drawings? We have had multiple ways going on here and have run into problems with the length of the slots in the model being different than the dimension because the length was appended to a rdim or the whole dimension was a note. We are looking at creating the dimension as a note and using the.
