4.4.6 Creating a Workpiece Coordinate
GSK928TE CNC system
Ⅱ
uses a floating workpiece coordinate which is the benchmark of
toolsetting and related dimension. After the system is installed, the workpiece coordinate must be
created firstly. When the actual position is inconsistent with that of the workpiece coordinate, the
coordinate is created again as follows:
（

）
Install the trial workpiece reliably on the machine, and select a tool (usually select the first
one used in machining).
Select the proper spindle speed, and then start the spindle. Traverse the tool in
“Manual”
mode, and cut a small sidestep of the workpiece.
X does not move but Z does to the safe position, and stop the spindle.
Measure the diameter of the cut sidestep. Press
to display Setting , and then
press
to display Setting X, at last, input the metrical diameter and press
,
so the system creates automatically X workpiece coordinate, if
is pressed , the
system cancels the creation of X workpiece coordinate.

Start the spindle again and traverse the tool to cut a face on the workpiece in
“Manual”
mode.

Do not move Z but X to the safe position, and stop the spindle.
Select a datum mark (it is a fixed point on the machine, such as the face of chuck, the datum
plane of fixture, which can ensure the created new workpiece coordinate system coincides
with the previous broken one). Measure Z distance from the cut end face to the datum mark.
Press
to display Setting and press
to display Setting Z , at last, input
the metrical diameter and press
, the system creates automatically Z workpiece
coordinate, if
is pressed , the system cancels the creation of Z workpiece
coordinate.
Clear out the previous system offset after the workpiece coordinate system has been
created as the above-mentioned operation. If the workpiece coordinate system is not
created, there is warp between the current X, Z coordinate values displayed and the actual
tool position. Initialize the system before creating the workpiece coordinate system.
4.4.7 Setting Program Reference Point
The program reference point can be any position on the machine. Once the program reference
point is created, the slider anywhere else will return to this point by executing the program
