Turn and Face Threading
Turn threading cuts the thread horizontally on the stock. Face threading cuts the thread
vertically on the stock.The type of threading is determined by the M (Face) parameter. If
no M is specified, M0 is the default.
The following entries are required to define a turn thread.
Figure 2–11. Thread Parameters
The following equivalents exist between the turn and face thread macro arguments.
Table 2–9. Threading Equivalents between Turn and Face Thread Macros
Thread Axis Turn Thread Face Thread
Thread Start K I
Thread Normal End Z X
Optional Thread End H S
Optional Thread End #2 Thread Start + T Thread Start + Td
Depth Axis Turn Thread Face Thread
Last Pass Depth X Z
Initial Depth Last Depth + J Last Depth + J
• The thread start, last pass depth, and total depth arguments (K,
X, and J for turn thread; I, Z, and J for face thread) must be
programmed for each thread cycle.
• Exactly one of the three thread arguments (Z, H, or T for turn
thread, X, S, or T for face thread) must be programmed for the
given type of thread cycle (turn or face).
