Coordinate transformation
If you should need a contour that has
already been programmed at another
position or in a different size, the TNC 640
offers you a simple solution: coordinate
transformation.
Depending on the machining task, you can,
for example rotate (milling), mirror (milling)
or shift the datum (milling and turning) in
the coordinate system. With a scaling
factor (milling) you can enlarge or reduce
contours to respect shrinkage allowance or
oversizes.

Program section repeats, subprograms,
program calls
Many machining operations repeat
themselves either on the same workpiece
or on different workpieces. Once you have
programmed a detail there is no reason to
have to program it again. With its subpro-
gramming feature, the TNC can save you a
great deal of programming time.
In program section repetition, you label a
section of the program and during program
run the TNC repeats the section succes-
sively as many times as required.
You can mark a program section as a
subprogram and then call it at any point in
the program and as often as you want.
With the program call function you can
even use a completely separate program
at any place in your current program. This
gives you convenient access to pre-pro-
grammed, frequently needed working
steps or contours.
Of course you can also combine these
programming techniques as often as
desired.
