MANUAL

OPERATION

Explanations

D Manual reference

The CNC machine tool has a position used to determine the machine

position return

position.

(See Section III-3.1)

This position is called the reference position, where the tool is replaced

or the coordinate are set. Ordinarily, after the power is turned on, the tool

is moved to the reference position.

Manual reference position return is to move the tool to the reference

position using switches and pushbuttons located on the operator’s panel.

The tool can be moved to the reference position also with program

commands.

This operation is called automatic reference position return (See Section

The tool can be moved in the following ways:

(i) Jog feed (See Section III-3.2)

The tool moves continuously while a pushbutton remains pressed.

(ii) Incremental feed (See Section III-3.3)

The tool moves by the predetermined distance each time a button is

pressed.

(iii) Manual handle feed (See Section III-3.4)

By rotating the manual handle,the tool moves by the distance

corresponding to the degree of handle rotation.

After the program is once registered in memory of CNC, the machine can

be run according to the program instructions. This operation is called

memory operation.

D DNC operation

In this mode of operation, the program is not registered in the CNC

memory. It is read from the external input/output devices instead. This

is called DNC operation. This mode is useful when the program is too

large to fit the CNC memory.

D Start and stop

Pressing the cycle start pushbutton causes automatic operation to start.

By pressing the feed hold or reset pushbutton, automatic operation pauses

or stops. By specifying the program stop or program termination

command in the program, the running will stop during automatic

operation. When one process machining is completed, automatic

operation stops.

Fig. 1.6 (b) Displaying and Setting Offset Values

The tool has the tool dimension (length, diameter). When a workpiece is

machined, the tool movement value depends on the tool dimensions.

By setting tool dimension data in CNC memory beforehand,

automatically generates tool routes that permit any tool to cut the

workpiece specified by the program. Tool dimension data is called the

offset value

(See Section III-11.4.1).

operation. This data causes machine characteristics to change.

For example, the following data can be set:

For example, CNC can specify the following:

S Rapid traverse rate of each axis

S Whether increment system is based on metric system or inch system.

S How to set command multiply/detect multiply (CMR/DMR)
