Example
Points P1 and P2 can then be described – with reference to the pole – as follows:
P1: Radius =100 / angle =30°
P2: Radius =60 / angle =75°

Absolute and incremental dimensions

Absolute dimensions
With absolute dimensions, all the position specifications refer to the currently valid zero
point. Applied to tool movement this means: The absolute dimension data defines the
position, to which the tool is to travel.
Example
The position data points P1 to P3 in absolute dimensions relative to the zero point are the
following:
P1: X20 Y35
P2: X50 Y60
P3: X70 Y20
