4. SUB CYCLE FUNCTION
OPERATION BY Symbolic FAPT
1 This function involves the creation of a macro call message.
It is a precondition, therefore, that the macro body has
previously been created on the NC side.
2 If the sub cycle process is to be corrected in the definition
of machining, a sub cycle file which is completely identical
to that during new creation must be existing in the main
3 The family program does not include the sub cycle file which
has been set. To correct the sub cycle process by inputting
a family program including the sub cycle into the process,
therefore, a sub cycle file which is completely identical to
that during new creation must also be input.
1 The tool locus is not drawn during the NC data preparation.
2 M01 is not output when the sub cycle ends even if “1” is set
to MTF NO.1136 (to output M01 when the process ends).
3 The sub cycle does not stop in the single step of the
4 It is impossible to create NC data for the 4–axis lathe or NC
data in the main and sub format if the process includes a sub
