later the axis reaches in-position. 0 means the axis is not configured.

For milling machine, 040114=211 means X/Y axis moves to the right

position and then Z axis reaches the right position.

For milling machine, 040114=101, it means that X/Z arrives at the

right position simultaneously and Y does not move.

 While using the "Designated N number" function, there should be

instruction address N at the block head.

Tool Setting and Machining Setup

Manual tool setting is completed mainly in "Coordinate system" and

"Tool compensation" sub-interfaces. For ease of user operation, the

system set two sub-interfaces in both "Machining" and "Setup" function

sets to reduce interface switching. The operating steps for both are

basically the same.

For some specific parts, the system can simplify manual tool setting

through "Workpiece measurement" function in "Setup" function set. This

function includes "Center measurement", "Plane measurement" and

"Circle center measurement" and is mainly used to set coordinates of X,

Y and Z axes automatically.

With the popularity of CNC machine tools, the application of tool setter

has become more widespread, and automatic tool setting has been

increasingly used. The system is configured with "Auto tool setting"

function in "Setup" function set, which can be used for automatic setup of

Z axis coordinates and tool length compensation.

8.2 Workpiece Measurement

"Setup" function set supports the workpiece measurement function. This

function supports center measurement, plane measurement and circle

center measurement, and the measurement results are calculated and

saved in the selected coordinate system.

8.2.1 Center Measurement

When the zero of the workpiece coordinate system is set in the symmetric

central position of the workpiece, this tool setting mode is applicable. The

system reads the coordinate value of machine tool in the same axial

direction when the tool touches both ends of the workpiece, and then

calculates the value of the zero of workpiece coordinate.

For vertical machine tools, the Z axis direction of the workpiece is not

centered. Thus, move the tool to the workpiece zero(generally on the

upper surface of the workpiece) during precutting, and keep the tool

position unchanged while setting A and B points on the interface. At this

time, press the 『Read measurement』 to read the machine coordinate

value of the tool, and the point is set as the zero point value of the

workpiece.

8.3 Automatic Tool Setting

"Automatic tool setting" submenu under "Setup" function set can measure

tool length automatically. The "Auto tool setting" function includes single

tool single workpiece measurement mode, single tool multiple workpiece

measurement mode and multiple tools multiple workpiece measurement

mode. The function interface is shown below. In the multiple tools

multiple workpiece measurement mode, the multiple tools can be

replaced automatically and the measured value of tool length can be

saved in the tool compensation interface.
