BALANCE CUT FAPT FUNCTION (2PATH LATHE ONLY)
WARNING
No check of the validity of a machining sequence is made.
Therefore, even when a machining sequence specified in
the machining definition includes any invalid process steps,
the entire machining sequence is reflected on the prepared
NC data. When defining machining, check the specified
machining sequence. Failure to specify a valid machining
sequence may result in the tool colliding with the workpiece
and/or machine, or forced machining occurring, possibly
causing damage to the machine and/or tool itself, or injury
to the user.
Machining conducted in one process by the tools of both head 1 and head
2 is called balance cut. The balance cut FAPT function automatically
generates NC data for balance cut. There are the following two types of
balance–cut machining.
Type A: This type aims at machining thin and long works with a high
precision. The two tools move in perfect synchronization with
each other.
Type B: This type aims at machining works more efficiently. After the
tool on head 1 cuts the work, the tool on head 2 cuts it deeper,
following the movement of the tool on head 1.
