Fig. 12.1 (a) Graphic range

As shown in Fig.12.1 (a), the maximum graphics range is an area of

approx. 144 mm (width) × 90 mm (height) for 7.2″/8.4″ LCD and approx.

240 mm (width) ×150 mm (height) for 9.5″/10.4″ LCD.

D Setting the graphics

To draw a section of the program within the actual graphics range, set the

range

graphics range using one of the following two methods:

1 . Set the center coordinates of the range and the magnification.

2 . Set the maximum and minimum coordinates for the range in the

program.

Whether 1 or 2 is used depends on which parameters are set last. A

graphics range which has been set is retained when the power is turned

off.

12. GRAPHICS FUNCTION

1. Setting the center

Set the center of the graphic range to the center of the screen. If the

coordinate of the

drawing range in the program can be contained in the above actual

graphics range and

graphics range, set the magnification to 1 (actual value set is 100).

graphics magnification

When the drawing range is larger than the maximum graphics range or

much smaller than the maximum graphics range, the graphics

magnification should be changed. The graphics magnification is 0.01 to

100.00 times, which is usually determined as follows;

Graphics magnification=Graphics magnification (H), or graphics

magnifications (V), whichever is smaller

Graphics magnification H =α/(length on program to horizontal

direction axis)

Graphics magnification V=β/(length on program to vertical

direction axis)

α:144mm (for seven soft key type)

β:90mm (for twelve soft key type)

α:240mm (for seven soft key type)

β:150mm (for twelve soft key type)

The graphics magnification is always based on the center of the screen.

With the above parameters, the center of screen (Gcx, Gcy, Gcz) is

determined by the CNC as follows;

Gcx = (X (MAX.) + X (MIN.) ) /2

Gcy = (Y (MAX.) + Y (MIN.) ) /2

Gcz = (Z (MAX.) + Z (MIN.) ) / 2

The unit of the value will be 0.001 mm or 0.0001 inch depending on the

input unit.

Graphics magnification is applied automatically. When the graphics

range is specified, the center coordinates and magnification do not need

to be calculated.

12. GRAPHICS FUNCTION

There are the following two functions in Dynamic Graphics.

12.2

DYNAMIC GRAPHIC

This is used to draw the path of tool center com-

Path graphic

manded by the part program.

DISPLAY

This is used to draw the workpiece figure machined by

Solid graphic

tool movement commanded by the part program.

The path graphic function is used to precisely check the part program for

drawing the tool path with a line. The solid graphic function is used to

draw the workpiece figure to be machined with a program. Thus, it is easy

to recognize roughly the part program. These two functions can be used

freely by switching them.

12.2.1

The path graphic feature calls a program from memory and draws the tool

path specified by the program. This feature provides the following

Path Drawing

functions.

1. Drawing plane

The user can choose the drawing plane from four types of plane views,

two types of isometric projection views, and biplane view.

2. Drawing rotation

When an isometric projection view is used, the drawing can be rotated

horizontally and vertically.

3. Drawing enlargement

A drawing can be enlarged or reduced by specifying a magnification from

and reduction

0.01 to 100 with respect to the actual size. In addition, a drawing can be

automatically enlarged or reduced by setting maximum and minimum

values.

4. Partial drawing

A range of the program can be drawn by specifying a starting sequence

number and ending sequence number.

5. Programmed path

The user can specify whether to apply tool length offset and cutter

and tool path

compensation to drawing. This way, either the actual programmed path

drawing

or the tool path can be drawn.

6. Color

When a tool path is drawn on a screen, the colors used can be chosen from

seven colors including white. The color of the tool path can be changed

according to the T code.

7. Automatic scaling

The CNC automatically determines the maximum and minimum drawing

coordinates for each program. This means that drawing can be performed

with a magnification automatically determined according to these

maximum and minimum values.

8. Partial enlargement

Except for biplane views the user can enlarge all types of drawings by a

drawing

factor of up to 100 while looking at the drawing that has been made.

9. Indicating the current

The current tool position can be displayed on the screen.

maximum and minimum coordinate values can also be set by performing

automatic scaling

D ANGLE

The direction of the coordinate axis is set when the isometric projection

is the setting of the drawing screen. The direction is set by horizontal and

vertical rotation angles. The unit is expressed in degrees.

D ROTATION

The horizontal rotation angle is set in the range of -180°to +180°in

reference to the vertical axis. Set a positive value for clockwise rotation

of the coordinate axis. Thus, the direction of projection (visual arrow)

becomes counterclockwise.

D TILTING

The tilting angle of the vertical axis is set in the range of -90°to +90°in

reference to the horizontal axis crossing the vertical axis at a right angle.

When a positive value is set, the vertical axis slants to the other side of

the graphic screen. Thus, the projection direction (arrow direction)

becomes the horizontal direction.

Tilting

D SCALE

Set the magnification rate of drawing from 0.01 to 100.00. When 1.0 is

set, drawing is carried out in actual dimensions. When 0 is set, the

drawing magnification rate is automatically set based on the setting of

maximum and minimum coordinate values of drawing.

D CENTER OR MAX./MIN.

When a graphics (drawing) magnification of

0 is set, maximum

coordinates on the X-axis, Y-axis, and Z-axis in the workpiece

coordinate system must be set in addresses X, Y, and Z, and minimum

coordinates must be set in addresses I, J, and K, to specify the graphics

(drawing) range. For biplane view drawing, maximum and minimum

coordinates for drawing must be specified.

When a drawing magnification other than 0 is set, the X, Y, and Z

coordinates of the drawing center in the workpiece coordinate system

must be set in addresses X, Y, and Z. Addresses I, J, and K are not used.

D Graphic program

No part program which has not been registered in memory can be drawn.

Also, it is necessary that the M02 or M30 should be commanded at the

end of the part program.

D Mark for the tool current

The period of mark blinking is short when the tool is moving and becomes

position

longer when the tool stops.

The mark indicating the current position of tool is displayed on the XY

plane view when the biplane drawing is performed.

D Position mark

Parameter 6501 (CSR, bit 5) is used to specify whether to use J or x as

the mark for indicating the current tool position and the center of a

partially enlarged drawing.

D Display of the coordinate

Parameter 6500 (DPO, bit 5) is used to specify whether to display the

value

coordinates of the current position on the tool path drawing screen.

D Changing the coordinate

If a program specifies a coordinate system change, parameter 6501 (ORG,

system

bit 0) is used to specify whether to draw without changing the coordinate

system or to draw by regarding the current drawing position as the current

position in the new coordinate system.

Restrictions

D Graphic condition

If machine operation is not allowed, no drawing can be carried out. No

drawing can be made during machine operation. The setting data and

switches required for drawing are as shown below:

D Partial enlargement

The partial enlargement can be carried out on the plane view and isometric

projection view. No partial enlargement can be made in the drawing of

the biplane view.

D Tool current position

In dynamic graphics display, drawing cannot be executed while the

machine is operating even though this is possible in ordinary graphics

display (see III-12.1). However, after drawing is executed, the operator

can see how the tool moves along the tool path by operating the machine

while displaying the mark for the current position of the tool.

It is necessary that the setting data and switches related to the machine

operation should be the same status between drawing operation and

machining operation for properly displaying the current position of tool

on the drawn tool path.

Press soft key [(OPRT)] and press either soft key [A.ST] or [F.ST].

When [A.ST] is pressed, the status of machining in progress is drawn

by simulation. When [F.ST] is pressed, the profile during machining

is not drawn. Only the finished profile produced by the program is

drawn. This allows drawing to be started.

When “STOP” is not displayed at the lower right corner of the screen,

the program is executed from its head.

“DRAWING” blinks at the

lower right corner of CRT screen during drawing.

11

Press soft key [STOP] to stop drawing temporarily. Drawing is

stopped after drawing the current block and “STOP” blinks at the

lower right corner of CRT screen. Press soft key [A.ST] or [F.ST]

when restarting drawing. Press soft key [REWIND] and then the

[A.ST] or [F.ST] if redrawing from the head. It is possible to continue

drawing after changing the solid graphic parameters in temporary

stop.

12

When the end of program (M02 or M03) is executed, the drawing

ends and the blinking of “DRAWING” stops. Then, the final finish

figure is drawn on the CRT screen. The drawn figure view is retained

until the power is turned off as long as a new machine figure view is

drawn.

D REVIEW

13

The color, intensity, or drawing direction of a machining figure which

has been drawn can be changed and the figure redrawn.

To redraw the figure, first change the parameters for the color,

intensity, or drawing direction on the SOLID GRAPHIC
