Press the CS SET key, then the value which can be figured out in

accordance with the measured values and the measurement mode, is

set to the displayed workpiece coordinate system offset. The

defined axis can only be the one that have values in the

measurement position.

Press the CS key to select one of the coordinate systems from G54

to G59 to define.

Press G54.X. In the input box, enter X value to define the required

coordinate system. Valid value: 0-60.

Press CTR MS: Enter the center measurement mode (by default).

Press PLN MS: Enter the plane measurement mode.

Press RC MS: Enter the circle center measurement mode.

Description

Operations on three measurement modes:

Center measurement

The measurement value display area is divided into Point A and

Point B. The default selection box is Point A; The default axis is the

X-axis; The background color is blue. Use the cursor keys to select

the axis to be measured, and the left and right keys to select Point A

or B.

Press the RD MV key, the system inputs the coordinate value

corresponding to the machine actual position into the selected box

with blue background, and automatically moves the selected box to

the Point B.

Press the CS SET key. Then the value, which the system figures out

via the formula of (measured value of point A + measured value of

point B)/2 for the defined axis, is displayed the specified coordinate

in area 2. If only the point A is measured while the point B is not

measured, the system displays the message "reading measurement

value failed".

5. Program Editing and Management

Plane measurement

Only one point coordinate is displayed in the measurement value

display area. The X axis is selected by default. The part to be edited

is in blue background. You may use the Up and Down keys to move

the cursor to the required axis.

Press the RDMV key, then the system inputs the corresponding

coordinate value of the machine actual position into the coordinate

of area 1. Press the CS SET key, then the axis whose value has been

read is set to the specified coordinate of area 2.

Circle Center Measurement

Point A, B, C are displayed in the measurement value display area.

The default plane is G17, default axes are X, Y axis. The X and Y

coordinates of point A are in the selection box with blue background.

You may move the cursor to the Plane and select the drop-down

box, click Enter, and select G17, G18, and G19 planes.

5. Program Editing and Management

The corresponding Coordinate are XY, XZ, and YZ.

Press the RD MV key, enter the corresponding coordinate value of

the machine actual position into the selected box with blue

background, and the selected box automatically moves to the next

point.

Press the CS SET key, then the system calculates the circle center

based on the three points, and input the calculated value to the

specified coordinate system of the area 2.

If one of the three point coordinate is not measured, the system

displays the message "Measurement failed"

mode. The feed rate specified in the program is ignored, and the feed

motion is at the dry running speed specified by the parameter. The feed

rate is limited by the maximum machining speed and controlled by the

feed override.

The Dry Running function does not conduct actual cutting, and is

intended to confirm the cutting path and program.

During the actual cutting, you need to disable the function; otherwise, it

may causes damages.

6.6 Breakpoint Related Operation

During machining, there are always some large workpieces which

requires complicated operation and long duration. It is necessary to save

and restore the breakpoint for further processing. In other words, you

may save the breakpoint (let the system remember various status of the

time point) before cut the power supply. After a period of time, you turn

on the power supply and restore the breakpoint (let the system restore the

status where the processing is broken) to proceed with the machining

from the breakpoint.

6.6.1 Save the Breakpoint

Operation procedure

Press the feed hold key to enter the feed hold mode (the indicator is

on).

Press Prog → BP.

Use the▲ and ▼ keys to select a storage path (press Enter to view

the folders in the selected storage path).

Press Enter, and the system will automatically create a file named

with the current program name. You may modify the name as

required.

Press Enter to confirm the operation.

6.6.2 Resume Breakpoint

Operation procedure

If the power is off after you save the breakpoint, you need to return

the tool back to the reference point after power on. Otherwise,

directly press Prog → BP.

Use the cursor keys to select the directory where the target file is,

switch to the file list, and select the breakpoint file to be loaded.

Press LOAD IN, the system will resume the breakpoint of the

program based on the information saved in the breakpoint file.

If axis motion has been conducted after breakpoint saving, you need to

return the axis to the position of breakpoint before proceeding the

program from the breakpoint. Follow the instructions below:

collision will occur when the tool returns to the breakpoint.

Under the MDI main menu, press TO BP. The system

automatically displays the breakpoint file information.

Press Start to start running, and the system moves the tool to the

breakpoint.

Press the Start button to proceed program from the breakpoint.
