1.    Manual Center

1.          To enter center submenu, press F1”Positon”=>F5”workpiece Coor”=>F5”Middle Func”.

2.          To change middle function to manual center, input 0(manual center) in center submenu, then press enter, manual center submenu can be displayed as follows.

3.          Take the tool to touch Px1 spot in the figure by handwheel, press F1”Px1”,the X machine coordinate value of Px1 can be noted in the screen and calculate X intermediate machine coordinate with Px2, the value can be displayed in Pxm and X-axis of Aux coordinate.

4.          Take the tool to touch Px2 spot in the figure by handwheel, press F2”Px2”,the X machine coordinate value of Px2 can be noted in the screen and calculate X intermediate machine coordinate with Px1, the value can be displayed in Pxm and X-axis of Aux coordinate.

5.          Take the tool to touch Py1 spot in the figure by handwheel, press F3”Py1”,the Y machine coordinate value of Py1 can be noted in the screen and calculate Y intermediate machine coordinate with Py2, the value can be displayed in Pxm and Y-axis of Aux coordinate.

6.          Take the tool to touch Py2 spot in the figure by handwheel, press F4”Py2”,the Y machine coordinate value of Py2 can be noted in the screen and calculate Y intermediate machine coordinate with Py1, the value can be displayed in Pxm and Y-axis of Aux coordinate.

7.          Press “Esc” to exit “Auto Center” and return to “Workpiece Coor” submenu.

8.          In “Workpiece Coor” submenu move cursor to the location of the workpiece coordinate which will be set, press F3 “AUX Latched”. At this time the system will set  the value of the AUX coordinate into the filed in accordance with the axis where the cursor stop.

 

2.    Auto Center

1.          To enter center submenu, press F1”Positon”=>F5”workpiece Coor”=>F5”Middle Func”.

 2.          To change middle function to auto center, input 1(auto center) in middle function submenu, then press enter, auto center submenu can be displayed as follows.

 3.          Choose the quadrant to process and input workpiece data, the description of the field to input an follows.

n   Workpiece length I: the workpiece actual length in X-axis direction

n   Workpiece width J: the workpiece actual width in Y-axis direction

n   Safe distance H: this is the length more than the distance between the start point of the tool P2 and workpiece, regardless of X-axis direction or Y-axis direction.

n   Feed rate: detection rate of auto center.

n   Z-axis safe height: this is the height that the tool will not encounter the workpiece when it moves above the workpiece,P1 in the figure as follows.

1.      Move to Z-axis Safe Height Teach, the location of P1 as displayed in the figure. Press F8 “Z safe height teach”, the value of Z-axis machine coordinate will be noted simultaneously as the safe height when tool moves above the workpiece.   

 2.        Move the tool down to P2 under the surface of work piece as the start point of auto center.

 3.          Press F2”Start”, the tool will be moved to touch the workpiece according to the data which has been set and the value will be displayed on the screen. Finally the center coordinate of the workpiece in XY-axis direction can be calculated.

 4.          Press “Esc” to exit “center function” back to workpiece coordinate submenu.

 5.          Move the cursor to the location of the workpiece coordinate which will be set in workpiece coordinate submenu. Press F3”AUX Latched” and the system will set the AUX coordinate Pxm or Pym into the workpiece coordinate system according to the axis that the cursor stops.
