- Graphic color

Set a graphic color number for a tool path for each of cutting feed and
rapid traverse.

1: Red 2: Green 3: Yellow 4: Blue

5: Purple 6: Sky blue 7: White

- Graphic range setting

Set a graphic range so that a tool path can be drawn in the tool path
graphic area.    Two methods are available:
1.  Method that sets graphic center coordinates and a scale
2.  Method that sets the maximum values and minimum values of a

graphic range

Whether method 1 or method 2 is used is determined by which
parameters were set most recently. A set graphic range is preserved
even if the power is turned off.

1. Method that sets graphic center coordinates and a scale

Set the coordinates of the center of a tool path graphic area in the
workpiece coordinate system. Then, set a scale used to contain the
graphic range in the tool path graphic area.
Set a scale value from 0.01 to 100 (magnification).
As a smaller scale is set, a tool path can be drawn in a wider range.
As a larger scale is set, a tool path is drawn by enlarging the tool path
around the graphic center coordinates.

2. Method that sets the maximum values and minimum values of a graphic range

Set the maximum coordinates and minimum coordinates of a desired
graphic range in the workpiece coordinate system. Drawing is
performed so that the specified entire range is contained in the tool
path graphic area.

From set maximum values and minimum values, graphic center
coordinates and a sale are automatically calculated to update the
graphic center coordinates and scale on the graphic parameter screen.

- 1909 -

When a scale is automatically determined, the scale is clamped to
within the range 0.01 to 100. Moreover, a maximum value must be
greater than the corresponding minimum value.

NOTE

When the maximum values and minimum values of

a graphic range are set, the graphic center
coordinates and scale are automatically updated.
However, when the graphic center coordinates and
scale are changed, the maximum values and
minimum values of the graphic range are not
automatically updated.

- Automatic erasure

Before drawing is started, the previous drawing can be erased
automatically.
1: Immediately before drawing is started, the previous drawing is

erased automatically.

0: The previous drawing is not erased automatically.

- Graphic axis number

Set which controlled axis to be assigned to which graphic axis.
For each controlled axis, set one of the following graphic axis
numbers:

First graphic axis:

Second graphic axis:

Third graphic axis:

Axis not used for drawing: 0

NOTE

1 When 0 is set for all controlled axes, it is assumed

that 1, 2, and 3 are set sequentially for the first to
the third controlled axes.

2 With the T series, a tool path is drawn along the

first and second graphic axes. No tool path is
drawn along the third graphic axis.

Operation for graphic parameter setting

Operation

- Moving the cursor

The cursor can be moved to a desired parameter by the page key

and the cursor key

, or

With the cursor keys, however, you cannot move from page 1 or 2 to
page 3.

- Input of settings (absolute input)

Method 1

(1) Key in a value to be set.
(2) Press the [INPUT] soft key.

Method 2

(1) Key in a value to be set.
(2) Press

the

key.

- Input of settings (incremental input)

Method 1

(1) Key in a value to be incremented to or decremented from

the current setting.

(2) Press the [+INPUT] soft key.

Procedure for tool path drawing

Procedure

- Start of drawing

(1) Display the tool path graphic screen.
(2) Press the [START] soft key.

The state that enables the movement of the tool in automatic
operation or manual operation to be drawn is set.
Afterwards, tool path drawing continues even if another screen is
displayed.

(3) Start automatic operation or manual operation.

- End of drawing

(1) Display the tool path graphic screen.
(2) Press the [END] soft key.

Tool path drawing ends.

- Erasure of the drawing

(1) Press the [END] soft key to end drawing.
(2) Press the [CLEAR] soft key. The tool path drawn so far is

erased.

NOTE

1 Set the machine lock state to perform drawing only

without moving the tool.

2 When the feedrate is high, the tool path may not be

drawn correctly. In such a case, decrease the
feedrate by performing, for example, a dry run.

Enlarged/reduced display

On the tool path graphic screen, you can move the center position of
the tool path drawing or enlarge the tool path drawing while viewing
the drawn tool path.
If any of these operations is executed, the tool path already drawn is
cleared.

- Procedure for changing the graphic range by setting a graphic center and

magnification

The center position of drawing can be moved.    At the same time, the
scale can also be changed.  So, the tool path can be enlarged or
reduced at a desired new center position.

(1)  Press the [SCALE] soft key then the [CENTER] soft key.

A yellow cursor appears at the center of the screen, and the soft
key display is changed.

(2) Move the yellow cursor to a new graphic center position by using

the cursor key

, or

(3) When changing the scale, key in a value from 0.01 to 100

(magnification) then press the [INPUT] soft key. An input
value is displayed at "SCALE" in the lower-right corner of the
screen.

When you press the [+INPUT] soft key, the current

magnification is incremented by an input value.

(4) Press the [EXEC] soft key to end the operation.

After this step, the setting for graphic movement is effective to
enable drawing with the new setting.

- Procedure for changing the graphic range with a rectangle

A tool path can be drawn by enlarging a specified rectangular area.

(1) Press the [SCALE] soft key then the [RECTANGLE] soft key.

Two cursors, one in red and the other in yellow, appear at the
center of the screen, and the soft key display is changed.

(2) Move the yellow cursor by using the cursor key

, or

. The cursor to be moved can be switched by

pressing the [CURSOR UP/DOWN] soft key.
Move the two cursors to the diagonal points of a new rectangular
graphic range. A tool path is drawn next time so that the drawn
tool path is contained in this rectangular range.

(3) Press the [EXEC] soft key to end the operation.

After this step, the setting of graphic enlargement is effective to
enable drawing with the new setting.

NOTE

1 To stop an enlargement/reduction operation, press

the [CANCEL] soft key.

2 Even if you perform an enlargement/reduction

operation, the tool path already drawn on the
screen is neither moved nor enlarged. The setting
for enlargement/reduction becomes effective
starting with tool path drawing after you press the
[EXEC] soft key.

DYNAMIC GRAPHIC DISPLAY

Overview

The dynamic graphic display function has two features:

•

Path

Drawing

The path of coordinates specified in a program is drawn on the
screen.
By displaying a travel path on the screen, the path can be
checked easily before performing machining actually.

•

Animation

The figure of a workpiece to be machined by a programmed tool
movement is drawn.
By drawing the three-dimensional figure of a workpiece to be
machined in an animation-like way, the intermediate machining
process and final figure can be grasped easily.

When machining is performed according to a program, this function
can draw a tool path with another program.
This function performs drawing much faster than the graphic display
function based on automatic operation, so that a program check can be
made more swiftly.
This function is distinguished from automatic program operation as
indicated by the following terminology:

Automatic operation

Operation performed for actual machining

Background operation

Virtual operation performed for drawing
