RUN 3-D DATA (Cycle G60)
1 From the current position, the TNC positions the tool in rapid
traverse in the tool axis to the set-up clearance above the MAX
point that you have programmed in the cycle.
2 The tool then moves at rapid traverse in the working plane to the
MIN point you have programmed in the cycle.
3 From this point, the tool advances to the first contour point at the
feed rate for plunging.
4 The TNC subsequently processes all points that are stored in the
3-D data file at the feed rate for milling. If necessary, the TNC
retracts the tool between machining operations to set-up
clearance if specific areas are to be left unmachined.
5 At the end of the cycle, the tool is retracted in rapid traverse to set-
up clearance.
8 PGM Name 3-D data : Enter the name of the file in which
the data is stored. If the file is not stored in the current
directory, enter the complete path.
8 Min. point of range: Lowest coordinates (X, Y and Z
coordinates) in the range to be milled.
8 Max. point of range: Largest coordinates (X, Y and Z
coordinates) in the range to be milled.
8 Set-up clearance 1 (incremental value): Distance
between tool tip and workpiece surface for tool
movements in rapid traverse.
8 Plunging depth 2 (incremental value): Infeed per cut.
8 Feed rate for plunging 3 : Traversing speed of the
tool in mm/min during penetration.
8 Feed rate for milling 4 : Traversing speed of the tool
in mm/min while milling.
8 Miscellaneous function M: Optional entry of a
miscellaneous function, for example M13.

Before programming, note the following:
Cycle G60 allows you to run 3-D data using several infeeds
which have been created with an off-line programming
system.
