Global data
The global data are divided into six groups:
„ Global data valid everywhere
„
Global data valid only for boring and drilling operations
„ Global data that determine the positioning behavior
„ Global data valid only for milling operations with pocket cycles
„ Global data valid only for milling operations with contour cycles
„ Global data valid only for probing functions
As already mentioned, global data are valid for the entire machining
program. Of course you can change the global data for any machining
step, if necessary:
8 Switch to the global data detail form for the machining step: In the
form, smarT.NC shows the parameters valid for this machining step
along with the currently active value. On the right side of the green
input field is a G as an identifier that this value is valid globally.
8 Select the global parameter that you want to change.
8 Enter the new value and confirm with the ENTER key. smarT.NC
changes the color of the input field to red.
8 On the right side of the red input field there is now an L as an identifier
that the value is valid locally.
