ShopMill can also process mold making programs in addition to programs for
the 2 1/2D machining. The mold making programs can be run not only on spe-
cial mold--making machines, but also on conventional milling machines for the 2
1/2D machining.
The milling machines must, however, be optimized for processing mold--making
programs to achieve the best possible velocity control.
You must perform the following steps to achieve the best possible velocity control:
Setting NCK machine data
S
Optimizing the drive
S
Preconfiguring and, if necessary, adapting the cycle "High Speed Settings"
S
The NCK machine data are set in the "Machine data" mask (see chapter 7.1
"NCK machine data for ShopMill").
Note
Please note that the settings of some machine data values depend on the CNC
control or are axis--specific; i.e. you must set these machine data values
yourself.
To adapt the drive for processing of mold making programs, you must optimize
all controllers (current controller, speed controller, position controller), the jerk
values and the feed forward control using machine--specific machine data, then
check these settings based on a circular mold test and contour precision (cor-
ners, radii).
The optimization of controllers, jerk values and feed--forward control should be
performed with active compressor function so that the compressor function can
later be activated without additional re--optimization.
The compressor function is already taken into account for the settings of the
machine data in the "Machine data" mask.
The compressor function is integrated in the option "Spline interpolation for
3--axis processing" (Order No. 6FC5 800--0AM16--0YB0) or "Spline interpolation
for 5--axis processing" (Order No. 6FC5 800--0AM17--0YB0).
The most important machine--specific machine data items are listed below.
This list is not necessarily complete.
