GRAPHICS FUNCTION
12
Two graphic functions are available. One is a graphic display function,
and the other is a dynamic graphic display function.
The graphic display function can draw the tool path specified by a
program being executed on a screen. The graphic display function also
allows enlargement and reduction of the display.
The dynamic graphic display function can draw a tool path and machining
profile.
In tool path drawing, automatic scaling and solid drawing are possible.
In machining profile drawing, the status of machining in progress can be
drawn through simulation. Blank figures can also be drawn.
The background drawing function enables drawing to be performed by
one program while machining is performed by another program.
This chapter mainly explains drawing procedures and drawing
parameters for the following:
1. Drawing the tool path specified by a program being executed, with the
graphic display function
2. Drawing the tool path with the dynamic graphic display function

In addition, it is also possible to enlarge/reduce the screen.
Before drawing, graphic parameters must be set.

1 . Set the center coordinates of the range and the magnification.
2 . Set the maximum and minimum coordinates for the range in the

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)

Graphic range (Max.) Z
Graphic range (Min.) X

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

GRAPHIC DISPLAY
This is used to draw the workpiece figure machined by

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.
The path graphic feature calls a program from memory and draws the tool
12.2.1
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 drawing
compensation to drawing. This way, either the actual programmed path
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.

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

maximum and minimum coordinate values of drawing.
D CENTER OR MAX./MIN.
When a graphics (drawing) magnification of

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:
Setting data and switch

Set it properly when performing drawing
while the tool offset amount becomes valid.

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.

12. GRAPHICS FUNCTION
12.2.2
The solid graphics draws the figure of a workpieces machined by the
movement of a tool.
Solid Graphics
The following graphic functions are provided :
1. Solid model graphic
Solid model graphic is drawn by surfaces so that the machined figure can
be recognized concretely.
2. Blank figure graphics
It is possible to draw a blank figure before machining.
A rectangular parallelepiped and a circular column or cylinder can be
drawn. A circular column or cylinder parallel to the X-axis, Y-axis, or
Z-axis can be selected.
3. Drawing of machining
It is possible to draw the progress of machining by simulation.
progress
4. Drawing of final machined
It is possible to draw the final finish machined figure.
figure
5. Changing of drawing direction
The user can choose from four drawing directions and eight tilting angles.
6. Plane view graphics
It is possible to draw XY plane views as well as solid model views. Height
of the workpiece is discriminated by color for color or brightness for
monochrome.
7. Triplane view graphic
In addition to a solid drawing, a triplane view can be drawn. The user can
choose from four types of plane view and side view positions. The user
can freely change the cross-section position of a side view.
8. Horizontal hole machining
It is possible to install tools in the direction which is parallel to the X or
Y axis as well as the Z axis.
9. Tool change during machining
It is possible to change tools during machining by the part program
command.

S Command of BLANK FORM
G10 L90 P_X_Y_Z_I_J_K_ ;
The command value succeeding the address is the same as the
