You perform important calculations every day, perhaps every hour, that make the difference between productivity and helpless floundering. Two points need to be made :

(1) Do you know the right Calculations ?
(2) Do all your shop floor Employees ?

Let's face it, people on you shop floor spend too much time looking for the "answer man" or digging in book's to find answers to their machining or math problems. It happens in every shop, and the amount of time wasted effects your companies bottom line.

See Formulas, Conversions, & Trigonometry For more helpful shop calculations!

Drill Point Length Calculation

The formulas below will calculate two dimensions commonly required in the Real World.
#1 - How deep to go with the countersink to get a specific diameter
#2 - How deep to drill to clear the tool tip through the part.

In the formula, DIA is the total tool diameter ( 1/2 drill = .500 ) and ANGLE is the TOTAL angle that the drill point is ground. A normal twist drill is about 135 degrees. As you can see, we divide both in half so radius values can be substituted and the formula altered as appropriate.

Thread Depth Calculation

The formulas below cover both Internal and External, standard 60 degree threads and will calculate the recommended depth of the thread. Depths calculated are Per Side depths to be used when determining the diameter to be programmed in the thread commands.
