6.2 Simulation window

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 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 blank.

 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.
