External Threads
For climb cutting external right hand threads a clockwise helical move G02 is made in the negative Z
direction. See figure below. In this example the tool makes a tangential arc on to the minor diameter of
the thread. Then is makes a clockwise move G02 to cut the thread. For a left hand thread a positive Z
helical movement would be required.
As noted on the previous page various thread mill tool suppliers software will create code for external and
internal threading. The following incremental thread program for an external UN 1-12 was created from
software downloaded from Advent Tool and Mfg. Inc. website: www.advent-threadmill.com
