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.
To support this arrangement in the orientation of graphics tools, the SIM graphics
module DPSMASCH.DLL has been expanded to include, among other things, an
almost universal evaluation of the TOA parameters. For example,
$TC_DP3[n,m]=... can also be evaluated with negative values, with the
convention that by default, positive lengths generally lead to machining "behind
the turning center" and negative lengths to machining "in front of the turning
center".
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 in SIM
ENDIF
...
Use (milling and lathe version):
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 lathe version) can be altered and adjusted, for example, to rotary
machines.
The INI entry [VIS] PLANE_VIEW=.. (in ..\user\dpmwp.ini for the mill version and
dptwp.ini for the lathe version) can be modified for this purpose.
In order for advantage to be taken of these possibilities in machines that differ from
the standard orientations,
• the value range for the entry has been published (B/F: back/front, U/D:
up/down, L/R: left/right) and
• the functionality for turning operations has been expanded accordingly
(including the derived views: external, half-section, full cut, surface area); note
that the previous wire model is retained
• In some cases (lathes) the entries have been made directly accessible on the
user interface:
