According to the MH holes for tapping have a range depending on depth of thread engagement. For Class 1A and 2A they are: up to 1/3D, 1/3D to 2/3D, 2/3D to 1 1/2D, 1 1/2D to 3D. The range covers about 60% to 80% thread depth.
Would it be better to just drop the 50% part of the G code calculator and let the savvy look up their hole sizes in MH and just focus on the G code? I'm adding spot drill for Rob and now reaming seems to be something to add... so far using this is faster than using my $$$$ CAM software for drilling and tapping holes :) JT On 8/14/2013 5:34 AM, Marius Liebenberg wrote: > JT > What is the correct way to calculate the drill sizes please.
