11.6 Generate a Backward Program
Function
With this TNC function you can reverse the machining direction of a
contour.
U Select the program whose machining direction you
want to reverse.
U Select the special functions
U Select the programming aids
U Select the soft-key row with functions for converting
programs
U Generate a forward and backward program
Note that the TNC may need many times more free
memory space on the hard disk than the size of the
program file to be converted.
The name of the file created by the TNC consists of the old
file name and the extension _rev. Example:
„ File name of the program whose machining direction is
to be reversed: CONT1.H
„ File name of the backward program to be generated by
the TNC: CONT1_rev.h
To be able to generate a backward program, the TNC must
first generate a linearized forward program, i.e. a program
in which all contour elements are resolved. This program
is also executable and has the file name extension _fwd.h.
