I l INTRODUCTION

1) Manual operation Manual reference position return (See Section 4.1)

The memory in the CNC machine tool holds the positional data for setting the machine. This position is called the reference position, where the tool is replaced or the coordinate are set.

narily, 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 push-

buttons located on the operator’s panel.

INTRODUCTION

Ordi-

Fig. 1 (a)

The tool can be moved to the reference position also with program commands. This operation is called automatic reference position return. (See Section 7.1)

b) The tool movement by manual operation

Using operator’s panel switches, pushbuttons, or the manual handle, the tool can be moved along

each axis.

2.1.8 Outline of operations

Select the data to be displayed and the major item to be entered on the

selection key (soft key).

Each major item is divided into minor items (called chapters). Select a chapter with the chapter selection soft key.

To perform a certain operation such as data input, select the operation with the operation selection soft key.

Pressing the operation selection key changes the soft key to the operation guide key. The executable operations can be checked with the operation guidance key.

Pressing some operation guidance keys immediately executes the corresponding operation. However, pressing other operation guidance keys displays a prompt for the operator to enter the data required for starting the corresponding operation.

Operation guidance keys that immediately execute an operation are displayed in higher intensity on the 9” monochrome CRT or in green on the displayed in blue-green.

When operation guidance keys that displays a prompt for the operator to enter the required data is pressed, if the address that corresponds to the data has been determined, the system automatically enters the address into the key-input buffer. Otherwise, the operator determines the address and inputs the data.

When the necessary data is entered in the key input buffer, the soft key changes to the EXEC key which starts execution.

Press the EXEC key after the necessary data is entered in the key input buffer. The corresponding opera-

tion is then performed.

When the latch is locked, the lever is horizontal. To store the tape reader

in the box, push the lever to release the lock, then raise the tape reader

with the handle to unlock the latch. When the latch is unlocked, the tape reader can be stored in the box. When storing the tape reader, secure it with the cover lock.

Manual Feed in a Specified Direction

The tool can be manually moved in a specified direction on a specified plane. The feedrate and the direction and plane of feed can be changed at any time. Simple cutting can be manually executed on a plane.

MANUAL OPERATION

(1) Selecting a plane

Specify external signals that indicate the first and second axes of the plane on which the tool is manually moved in a specified direction.

(2) Specifying the direction of feed

Enter an external input signal that indicates the direction in which the tool is to be manually moved. The direction of feed can be specified in the range of 0 to 360 degrees in 1 The angle is specified as shown below.

degrees.

If an angle greater than 360 degrees is specified, the CNC unit repeatedly subtracts 360from the angle

until it falls within the range of 0 to 360 degrees. While the tool is being manually moved in the specified direction, the direction of feed can be changed

as required. When the direction is changed, the position check is not executed, but the move com-

e) When the tape commands are followed by an incremental command, they are executed in the same

manner as when the absolute switch is off.

NOTE 1

1) Coordinates when the switch off and tool nose radius compensation is being performed

2) When the switch is on during tool nose radius compensation

When the operator manually intervenes during tool nose radius compensation, the tool moves as described below:

After manual operation is performed in the status of manual absolute switch is off, during cutter compensation, automatic operation is restarted then the tool moves parallel to the movement that would have been performed if manual movement had not been performed. The amount of separation equals

to the amount that was performed manually.

Operation of the machine upon return to automatic operation after manual intervention in the status of manual absolute switch is on, during execution with an absolute command program in the cutter compensation mode will be described. The center of the tool is directly moved to the top of the vector at the beginning of the next block. After that point, the distance of manual movement is taken into consideration when the vector is calculated. The same occurs when manual intervention is executed

while turning a corner.

If the INC bit in parameter No. 2402 is set to I when the program does not contain absolute commands but incremental commands, the tool is moved in the same manner as when the switch is off. bit is set to 0, even the incremental command is processed like the absolute command as described below.

Executing Automatic Operation

While executing a block, the CNC usually calculates the next block to convert it into data in the executable form. This is called buffering.

The number of blocks to be buffered has been extended to 2, and the two blocks are preread so far as time permits. This prevents an interruption in the pulse distribution between two successive small blocks.

The XBUF bit in parameter No. 7616 determines whether the number of blocks to be buffered is extended to

A program of type P cannot be restarted under the following conditions:

(i)

When automatic operation is not performed after the power is turned on

(ii) When automatic operation is not performed after the coordinate system is set, changed, or

shifted (Shifting the coordinate system refers to changing the offset from the external piece reference point.)

If there are blocks that follow the block in which the coordinate system is set or changed last while machining is suspended, the blocks can be restarted normally by restarting the program of type

Whenever the tool is moved along each axis to the machining restart position in both programs of types P and Q, a single-block stop is valid after the tool has moved along one axis. In this

case, however, manual intervention from the MDI panel is not possible.

The tool can be manually moved. When the tool is already returned along an axis, however, it

is not moved manually along the axis.

When searching for a block, unless the conditions such as the input signals and offsets are the same as those when machining was performed last, the tool does not return to the correct restart position. turned on or when the mode selector is switched between the MEMORY and TAPE positions.

If one of the following conditions occurs, retry the operations for restarting the program from the beginning:

The [FEED HOLD] switch is turned on while

The system is reset while or after the block is searched for.

If the [CYCLE STA#TI button is pressed when the program restart switch is turned on, the opera-

tion is ignored, and a warning message is displayed.

Manual operation must be performed in the manual absolute mode irrespective of whether it is performed before or after machining.

In general, the tool cannot be returned to the correct position if one of the conditions occurs:

(i)

The tool is manually moved when the

(ii) The tool is moved in the machine lock state without considering the movement along the

(iii)

The mirror image function is used.

(iv) No coordinate system is specified at the beginning of the program during incremental pro-

gramming.

(v) The tool is manually moved while it is being automatically returned along the axes.

(vi) The machine lock state is released after the command for restarting the program is

in that state.

(vii) Restarting the program is specified in a block between the block for skip cutting and the

sequent absolute command block.
