Configuring the HMI system
2.4 Simulation
If a cycle is changed, it must be copied into the simulation using the "Match cycles" softkey.
Only cycles that have changed since they were last accessed are copied into the simulation
(along with newly imported cycles).
Cycles in the simulation that have since been deleted are deleted from the simulation. If an
automatic cycle interface is not used, the simulation must be restarted.
Mirroring tools
Differently oriented tool carriers (e.g. in different NC channels) can be used in the same
machine tool, for which the TOA length compensation parameters are subject to machine
tool-specific frame transformations (e.g. MIRROR) and have to be specified differently from
the usual settings.
In order to be able to support this constellation when orientating the graphic tool, the SIM
graphic module DPSMASCH.DLL among others, is expanded, in the turning version, by an
essentially universal evaluation of the TOA parameter.
e.g. $TC_DP3[n,m]=... can also be evaluated with negative values with the convention so
that as standard positive length dimensions generally result in a machining "behind the
center of rotation" and negative length dimension results in machining "in front of the center
of rotation".
Special NC instructions may also be needed in the corresponding user cycles for tool carrier
selection to ensure that the simulation proceeds with the correct orientation of the graphics
tools, e.g.
...
IF $P_SIM
$SC_MIRROR_TOOL_LENGTH=1 ; tool length compensation
mirror mirrored axes for SIM
ENDIF
...
Operator control (milling and turning):
The sign-compliant evaluation of the TOA parameters at the interface to the graphics module
means that no operator action is required.
Rotating the coordinate system
The orientation of the coordinate system for simulation views (until now largely incomplete in
the turning version) can be altered and adjusted, for example, to rotary machines.
For this purpose, the INI entry [VIS] PLANE_VIEW=.. (in ..\user\dpmwp.ini for the milling
version or dptwp.ini for the turning version) can be modified.
In order for advantage to be taken of these possibilities in machines that differ from the
standard orientations, the value range of the entry is published (B/F: back/front, U/D:
up/down, L/R: left/right) and the functionality during turning expanded accordingly (incl. the
derived views: Outside cut, half cut and full cut, surface area) (wire model is kept as before!).
