THREAD MILLING TOOLS USER GUIDE iniuf nr Thread Milling CNC Program for Internal Thread Right-hand thread (climb milling) from bottom up. Program is based on tool center. This method of programming needs no tool radius compensation value, other than an offset for wear. A= Do - D 2 A = Radius of tool path Do = Major thread diameter D = Cutting diameter General Program G90 G00 G54 G43 H1X0 Y0 Z10 S... G00 Z-(to thread depth) G01 G91 G41 D1 X(A/2) Y-(A/2) Z0 F.
