Milling Cycles
3.16 Swiveling – CYCLE800 (SW 6.2 and higher)
Example 3: Table 2
In this example, the offset vectors are not defined as described for
example 3, but as a closed system as defined below:
Offset vector I2: Distance between machine reference point
Offset vector I3: Distance between point on rotary axis 1
Offset vector I4: Distance between point on rotary axis 2
The advantage of this method is that the
position values do not changed in the unswiveled state,
regardless of whether or not the swivel table is selected.
