NOTE:  Reference #1 as shown in the PSI bulletin dated 9/2/20 appears to be a very old out-of-print version.  We don't consider the titles listed above as "code books" which usually contain statutes.  This is the reason we have replaced the bulletin titles with the most up-to-date versions (see bulletin statement titled "REFERENCE LIST").

Reference #3 has the wrong title shown in the bulletin.  It should say the "Toolbox" version.

Books NOT Allowed
CNC Machining, 2009, 1st Edition, Gizelbach
