Single point turning of a thread can seem extremely difficult until you successfully do it One area of frustration is knowing how deep to go with the cutter The procedure that Frank shared with me removes much of this frustration This is a quick and easy way to single point turn threads It is not a precision method

2006 02 01 nbsp 0183 32 Many engineers define multiple start threads much like they define single start threads The major or minor diameter is specified along with the number of threads per inch While this will allow you to calculate the pitch of the thread you must know the number of starts on the thread in order to determine the lead for each start The thread shown in Figure 1 is a

Assuming you started at the nominal diameter you come down by H 8 in radius which is H 4 in diameter 4Recall that the thread depth H approximately equals 0 866 times the pitch and the pitch is 1 divided by the threads per inch So H ≈ 0 866 x 0 75 x P 0 65P R G Sparber September 4 2011 Page 23 of 30
