Sloted Hole

[91077]

What is the proper way to label a sloted hole on my drawing?

 

[Heckler]

Dimension the slot width and make the Radius Typical. Dimension the overal slot length from the tangent point on the arcs. You can add true position callout if you so desire with boundary conditions or edge profile....that would depend on your machine shop. Check ASME Y14.5M for reference on this.

Dimension the slot width and make the Radius Typical

I have got to heckle Heckler on this one. I reject every drawing that crosses under my red pen dimensioned this way.

The slot width is the same as the diameter (not radius) of the end arcs, anyhow. Dimensioning the radius of the end arc is worse than useless.

Dimension a slot the same way a toolmaker will check it, width by length. Do this either with two separate dimensions or with a single note.

To make a single note, go to the part and make a custom property for the dimension note. You can add dimensions to properties by clicking visible dimensions when the custom property editor is active. Then use the custom property in a note in the drawing.

I could be the world's greatest underachiever, if I could just learn to apply myself.

Well well - I appears we're not far off. I was trying to say put the radius dim as "2X R" to denote a full radius. Their are many schools of thought on the topic of "what is the correct way to dimension a drawing". I see a lot of different ways being a contract manufacturing house. The Germans are the most interesting.

Dim per Tick, and add "R FULL". This clarifies the radii for the machinists.
