Interpolate Axes 237
In this example, the absolute endpoints of the X and Y axes are the same
as their start points, because an integral number of complete revolutions
were made. If the specified arc angle is not an integer, the endpoints of the
X and Y axes are not be the same as their start points.
Example 8: Helical Interpolation in Incremental Mode
In incremental mode, enter the distance from the current position of both
the X and Y axes to the center of the circle in the With Center At fields.
Then specify the helical moves distance along the Z axis, and the number
of turns the X-Y plane will make around the Z axis.
For example, if the following bullets are true, and the Interpolate Axes
parameters area as shown below, it produces the same motion as shown
previously for absolute mode.
Axis 0 is the X axis and is currently located at absolute position –10
position units
Axis 1 is the Y axis and is currently located at position +10 position
units
Axis 2 is the Z axis and is currently located at position –5 position
units
