Edge measurement

The following options are available to you when measuring an edge:
Aligning the edge
The workpiece lies in any direction, i.e. not parallel to the coordinate system on the work
table. By measuring two points on the workpiece reference edge that you have selected, you
determine the angle to the coordinate system.
Distance between 2 edges
The workpiece lies parallel to the coordinate system on the work table. You measure
distance L of two parallel workpiece edges in one of the axes (X, Y, or Z) and determine its
center.
Precondition
You can insert any tool in the spindle for scratching when measuring the workpiece zero
manually.
- OR -
An electronic workpiece probe is inserted in the spindle and activated when measuring the
workpiece zero automatically.
