Setting up the views
With the simulation windows described in the following you check not
only the turning work but also the drilling and milling operations.
 XZ view (turning view): The turning contour is depicted in the XZ
coordinate system. The configured coordinate system is taken into
account (tool carrier in front of/behind the turning center, vertical
lathes).
 XC view (face view): The displayed coordinate system is displayed
as a Cartesian system with the axis designations XK (horizontal) and
YK (vertical). The angle position C=0° is on the XK axis, the positive
direction of rotation is counterclockwise.
 ZC view (lateral surface view): The contour display and traverse-
path display are oriented to the position on the unrolled lateral
surface and the Z coordinates. The upper and lower lines of this
workpiece correspond to the angular positions C=–180°/+180°,
respectively. All drilling and milling operations are within the range –
180° to +180°.
 Cycle program or DIN program with workpiece blank
definition: The basis for the unrolled workpiece surface is the
dimensions of the programmed workpiece.
 Cycle program or DIN program without workpiece blank
definition: The basis for the unrolled workpiece surface is the
dimensions of the "standard blank" (user parameter: "simulation >
definition of the standard workpiece blank size").
 Single cycle or Teach-In: The basis of the unrolled workpiece
surface is the section defined by the respective cycle (expansion
in Z and limiting diameter X).
 YZ view (side view): The contour and traverse path are shown in
the YZ plane. The side view depicts only the Y and Z coordinates—
not the spindle position.
Front face and surface windows operate with a fixed
spindle position. Whereas the machine turns the
workpiece, the graphic simulation moves the tool.
