7. Machine Basic Operation

7.1 ZRN Operation

After turn on the machine, return every axis to zero point for building up the reference position as the according of the movement of the coordinate, therefore it can run automatically

7.1.1 Operation Steps

(1) Click the【Maximize】button of [Controller function area]

(2) Click the【Machine】coordinate function button

(3) Check the Work coordinate: Add the coordinate positions of work offset and tool offset

according to the machine coordinate

(4) Click the【Actual Value MCS】button of the menu, switch the window to

machine coordinate (Machine) checking window.

(5) Check the machine coordinate value (Machine)

[Work Coordinate (WCS)]:Add work offset and tool offset coordinate position with

The machine coordinate.

[Machine Coordinate(MCS)]: Use machine zero point as the coordinate position of

Reference zero point.

(6) Click the [JOG] mode of the controller panel

(7) When the light of [JOG mode] is on, click [REF.POINT mode]

(Return to Reference Point)

(8) Click [Z] button

(9) Click [+] button, axis return to the zero point of Z axis with rapidly speed

(10) When the machine coordinate of Z axis is 0, it will show up the symbol,

it means zero point returning of Z axis is done.

(11) Continue to execute the zero point returning movement of X and Y Axis

7.2 Method of Tool Movement

7.2.1 Rapid Movement

7.4.3 Work Coordinate Setting

Definition of WORK OFFSET:

(1) The shifted distance between zero point of the work and the home position of

the machine is called as Work Coordinate Offset Value (Work Coordinate Setting)

(2) Define the offset value of workpiece XY Axis through the offset action with the

[Edge Finder]
