System
This chapter presents practice on the procedures for aligning the
part coordinate system using the model workpiece.

3.1 Aligning Part Coordinate System

When the data processing unit is turned on, the coordinate values in the coordinate system
matching the moving directions of the XY table are output as measurement results. (See Fig.
3-1-1.)
Y
(x, y)
(0, 0)
Fig. 3-1-1
Therefore, in order to correctly evaluate information such as the center coordinates of a circle
on a workpiece as dimensions, the coordinate system must be aligned to match the workpiece’s
position and orientation.
The aligned coordinate system is called the part coordinate system (PCS). (See Fig. 3-1-2.)
X
No. 99MBA038A

Once the part coordinate system is set, it is possible to obtain precise measurements and
calculations even if the workpiece’s orientation is not adjusted to be parallel with the moving
directions of the XY table.

5.1 AI Measurement Function

The AI measurement (Artificial Intelligence measurement) is a function of automatically
recognizing the type of the measured basic feature, such as a circle, a straight line, etc. from
measured points data. The following types of basic feature can be automatically recognized by
the system using the AI function.
This chapter presents practice for measurements utilizing artificial
intelligence (AI), using the model workpiece.

1 Point
2 Line
3 Circle
4 Distance
5 Ellipse
6 Rectangular hole
7 Slot
8 Point & angle
TIP
See Chapter 4 of the “Software Guide” for further details on the AI function.
