We have been dimensioning our blind holes from the start surface to the drill point. This is being done at the request of our machine shop. I was told that the reason is, the cnc operators want be be able to compare the depth readout on their cnc's with the value in the drawing note.
Every standard I have seen calls for holes to be dimensioned to their full diameter depth.
Has anyone else dealt with this issue? Should the cnc operators really need the bind holes dimensioned to the drill point? We are going thru our company standards and I would like to know if we should join the
99% of companies that dimension to the full diameter depth or not.I need a further explaination of the pros and cons of this practice so we can decide which way to go.
Thanks,
