Fig. 13.1.2 (a) Straight Thread Cutting
In incremental programming, the sign of numbers following addresses
U and W depends on the direction of paths 1 and 2. That is, if the
direction of path 1 is the negative along the X axis, the value of U is
negative. The range of thread leads, limitation of spindle speed, etc.
are the same as in G32 (thread cutting). Thread chamfering can be
performed in this thread cutting cycle. A signal from the machine tool,
initiates thread chamfering. The chamfering distance is specified in a
range from 0.1L to 12.7L in 0.1L increments by parameter (No. 5130).
(In the above expression, L is the thread lead.) In the single block
mode, operations 1, 2, 3, and 4 are performed by pressing cycle start
button once.
