3. MANUAL OPERATION

When the switch is ON during tool nose radius compensation

Operation of the machine upon return to automatic operation after manual

intervention with the switch is ON during execution with an absolute

command program in the tool nose radius compensation mode will be

described. The vector created from the remaining part of the current block

and the beginning of the next block is shifted in parallel. A new vector is

created based on the next block, the block following the next block and

the amount of manual movement. This also applies when manual

operation is performed during cornering.

Manual operation performed in other than cornering

Assume that the feed hold was applied at point P_H while moving from P_A

to P_B of programmed path P_A, P_B, and P_C and that the tool was manually

moved to P_H’. The block end point P_B moves to the point P_B’ by the

amount of manual movement, and vectors V_B1 and V_B2 at P_B also move

to V_B1’ and V_B2’. Vectors V_C1 and V_C2 between the next two blocks P_B

- P_C and P_C - P_D are discarded and new vectors V_C1’ and V_C2’ (V_C2’ =

V_C2 in this example) are produced from the relation between P_B’ - P_C and

P_C - P_D. However, since V_B2’ is not a newly calculated vector, correct

offset is not performed at block P_B’ - P_C. Offset is correctly performed

after P_C.

Procedure for Manual Linear/Circular Interpolation

Procedure

1

To perform manual handle feed, select manual handle feed mode. To

perform jog feed, select jog feed mode.

2

To perform manual handle feed, select a feed axis (for simultaneous

1-axis feed along the X-axis, Y-axis, or Z-axis, or for simultaneous

linear or circular 2-axis feed along a specified straight line or circle in

the XY plane) subject to manual handle feed operation. Use the

handle feed axis select switch for this selection.

To perform jog feed, select a feed axis and direction with the feed axis

direction select switch. While a feed axis and its direction are

specified, the tool moves in the specified axis direction or along a

straight line or circle at the jog feedrate specified in parameter No.

1423.

3

For manual handle feed

The tool is moved along a specified axis by turning the respective

manual handle. The feedrate depends on the speed at which the

manual handle is turned. A distance to be traveled by the tool when

the manual handle is turned by one pulse can be selected using the

manual handle feed travel distance magnification switch.

3.MANUAL OPERATION

OPERATION

B-63524EN/01

For jog feed

The feedrate can be overridden using the manual feedrate override

dial.

The procedure above is just an example. For actual operations, refer

to the relevant manual provided by the machine tool builder.

Explanations

D Definition of a straight

For feed along an axis, no straight line/circle definition is required. For

line/circle

linear feed or circular feed, a straight line or circle must be defined

beforehand. (For circular feed, for example, data such as a radius and the

center of a circle must be set.) For details, refer to the relevant manual

provided by the machine tool builder.

D Manual handle feed

In manual handle feed, the tool can be moved along a specified axis

(X-axis, Y-axis, Z-axis, ..., or the 8th axis), or can be moved along a

tilted straight line (linear feed) or a circle (circular feed).

(1) Feed along a specified axis (simultaneous 1-axis control)

By turning a manual handle, the tool can be moved along the desired

axis (such as X-axis, Y-axis, and Z-axis) on a simultaneous 1-axis

control basis. (This mode of feed is the conventional type of manual

handle feed.)

(2) Linear feed (simultaneous 2-axis control)

By turning a manual handle, the tool can be moved along the straight

line parallel to a specified straight line on a simultaneous 2-axis

control basis. This manual handle is referred to as the guidance handle.

Moreover, by turning another manual handle, the tool can be moved

at right angles to a specified straight line on a simultaneous 2-axis

control basis. This manual handle is referred to as the approach

handle. When the guidance handle or approach handle is turned

clockwise or counterclockwise, the tool travels forward or backward

along the respective path.

(3) Circular feed (simultaneous 2-axis control)

By turning a manual handle, the tool can be moved from the current

position along the concentric circle that has the same center as a

specified circle on a simultaneous 2-axis control basis. This manual

handle is referred to as the guidance handle. Moreover, by turning

another manual handle, the tool can be moved along the normal to a

specified circle on a simultaneous 2-axis control basis. This manual

handle is referred to as the approach handle. When the guidance

handle or approach handle is turned clockwise or counterclockwise,

the tool travels forward or backward along the respective path.

Explanations

D Positioning

An amount of travel is given as a numeric value, preceded by an address

such as X, Y, or Z. This is always regarded as being an incremental

command, regardless of whether G90 or G91 is specified.

The tool moves along each axis independently at the rapid traverse rate.

Explanation

The previous explanation of how to execute and stop memory operation

also applies to MDI operation, except that in MDI operation, M30 does

not return control to the beginning of the program (M99 performs this

function).

D Erasing the program

Programs prepared in the MDI mode will be erased in the following cases:

D In MDI operation, if M02, M30 or ER(%) is executed.

(If bit 6 (MER) of parameter No. 3203 is set to 1, however, the program

is erased when execution of the last block of the program is completed

by single-block operation.)

D In MEMORY mode, if memory operation is performed.

D In EDIT mode, if any editing is performed.

D Background editing is performed.

D When the

O

and

DELETE

key are pressed,

D Upon reset when bit 7 (MCL) of parameter No. 3203 is set to 1

D Restart

After the editing operation during the stop of MDI operation was done,

operation starts from the current cursor position.

D Editing a program during

A program can be edited during MDI operation. The editing of a program,

MDI operation

however, is disabled until the CNC is reset, when bit 5 (MIE) of parameter

No. 3203 is set accordingly.

Limitation

D Program registration

Programs created in MDI mode cannot be registered.

D Number of lines in a

A program can have as many lines as can fit on one page of the screen.

program

A program consisting of up to six lines can be created. When parameter

MDL (No. 3107 #7) is set to 0 to specify a mode that suppresses the

display of continuous-state information, a program of up to 10 lines can

be created.

If the created program exceeds the specified number of lines, % (ER) is

deleted (prevents insertion and modification).

D Subprogram nesting

Calls to subprograms (M98) can be specified in a program created in the

MDI mode. This means that a program registered in memory can be

called and executed during MDI operation. In addition to the main

program executed by automatic operation, up to two levels of subprogram

nesting are allowed (when the custom macro option is provided, up to four

levels are allowed).
