Workpiece Origin
Fig. 3-27 First Presetting
The first presetting finishes, and workpiece machining begins.
After tool change or tool break, press F6 [Tool Cali], and then press F2 [Second Cali] in the new
pop-up manipulation button bar to restore the Z workpiece coordinate value of current point, as
shown in Fig. 3-28. The system ends this process automatically.

3.8 Offset Setting
3.8.1 WCS (Workpiece Coordinate System)
In programming, programmers select one certain given point on workpiece as origin (also called
programming origin) to establish a new coordinate system (i.e. workpiece coordinate system), also a set
of right-hand coordinate system. The origin of WCS, i.e. workpiece origin, is fixed relative to a certain
point on workpiece and floating relative to the machine origin. The selection of origin of WCS should
meet the conditions of simple programming, simple dimensional conversion, and small caused
machining error.
