HEIDENHAIN CNC PILOT 640 9
 The new TURN PLUS function automatically generates NC
programs for turning and milling operations based on a fixed
machining sequence (see smart.Turn and DIN Programming User's
Manual).
 The G940 function now provides a way to calculate the tool lengths
in the basic (definition) position of the B axis (see smart.Turn and
DIN Programming User's Manual).
 For machining operations that require rechucking, you can define a
separation point on the contour description with G44 (see the
smart.Turn and DIN Programming User’s Manual).
 The G927 function enables you to convert tool lengths to the
reference position of the tool (B axis = 0) (see smart.Turn and DIN
Programming User's Manual).
 Recesses that were defined with G22 can now be machined with
the new Cycle 870 ICP Recessing (see smart.Turn and DIN
Programming User's Manual).
