3.17.3 Customizing technology

With input field "Customizing technology" "Yes", both the machine
manufacturer and the operator/programmer can customize the
technology for HSC machining.
Always take note of the technology of the subsequent CAM
program.
Customization by the machine manufacturer
Preconditions:
• The manufacturer password is set,
• Input field "Customizing technology" à "Yes"
When the interactive cycle screen form CYCLE832 is opened,
the parameters are preassigned with the values of GUD7
variables _TOLV[n], _TOLT[n]. (n = machining: finishing, rough-
finishing, roughing, deselection)
When the parameters are changed, the values are written directly
to the GUD7 variables _TOLV[n] or _TOLT[n].
This gives the machine manufacturer the opportunity to customize
the basic settings to his machining tasks.
Example:
Calling cycle CYCL832 roughing with three axes machining axes
tolerance 0.1mm with G642 (Siemens default values).
The machine manufacturer can modify the roughing technology
with setting: machining axes tolerance 0.3mm, TRAORI, G641.
Each time the tolerance cycle is called, this setting is then
displayed and takes effect during the execution.
Notes for the machine manufacturer
1. In order to optimize the path control response when traversing
with G64, in CYCLE832, the velocity jumps overload factor is
recalculated in accordance with the following table:
