Solidworks hole depth dimension
Solidworks hole depth dimension
(OP)
When I use the wizard to create a tapped hole I use the callout of oh, say #8-32 tap, .600 deep and SW makes a hole with the cylindrical depth of .600, plus the angled tip extends .041".
When BobCAM creates a tool path for this it has to go .641 deep, which does produce the correct hole. Is this difference because of some engineering standard on hole callout?
Another way to state my question is, why doesn't SW make a hole .600" to the tip of the drill bit?

Any experienced CAM programer (or modern CAM software) should automatically account for the drill point.
As a former machinist (8 years on the shop floor) I recommend that you never bottom tap a hole unless absolutely necessary. (Allow liberal bottom clearance as some the chips will fill up the bottom of the hole causing the tap to seize and break. I suspect that broken taps cause more lost parts than any other operation.)
