Configuring cycles
22.6 Swiveling
Example 4: Swivel head/rotary table "MIXED_45"
Vectors relate to the basic setting of the kinematics
Rotary axis vector V1: Rotary axis B rotates around Y and
Rotary axis vector V2: Rotary axis C rotates around Z.
Offset vector I2:
Offset vector I1:
Offset vector I3:
Offset vector I4:
Side view of the
machine:
Spindle (tool adapter) is positioned on a block dimension above the top edge of the table
(rotary axis C) or the center of the table. A measuring rod in the spindle is used to determine
the turning center of rotary axis C.
