Swivel head (type T)
Offset vector I1
Rotary axis vector V1
Offset vector I2
Rotary axis vector V2
Offset vector I3
The vector meanings are as follows:
References:
• Offset vector I1
à Distance between reference point of toolholder and
rotary axis 1
• Offset vector I2
à Distance between rotary axis 1 and rotary axis 2
• Offset vector I3
à Distance between rotary axis 2 and tool reference
point
• Offset vector I4
à Distance between rotary axis 2 and table reference
point
• Rotary axis vector V1
à Direction of rotary axis 1
• Rotary axis vector V2
à Direction of rotary axis 2.
The offset vectors must not necessarily point to the pivot
point of the rotary axes, but it is important that they are
directed towards a point in the direction of rotation.
The plus/minus sign of the rotary axis vectors is
determined by the direction of rotation of the particular
rotary axis around the corresponding machine axis.
