9.1

DRAWING DURING MACHINING (TOOL PATH)

While a machining operation is being performed on the machine, the

tool path can be drawn. This function is available also during machine

lock and dry run operation.

NOTE

1

To perform drawing during machining, open the window for drawing

during machining by pressing [GRP ON] before starting machining

operation.

2

If a coordinate system change is specified in the program during

drawing, drawing is performed without changing the coordinate

system.

3

In the drawing during machining, when the workpiece specifying

block is executed, form of a workpiece is drawn in form of wire

frame. Drawing color of the workpiece can be specified by the

parameter No.14773.

4

When a simulation window is opened, a blank figure drawing at the

last drawing is displayed. However, if bit 4 of parameter No. 27310 is

set to 1, no blank figure is displayed when a simulation window is

opened.

5

Tool path drawing with a multi-path system is performed only at the

selected path for displaying. And a simulation window is initialized if

the selected path for displaying is changed. So if the selected path

for displaying is changed in displaying a free blank figure, the

drawing is initialized for a column figure which encloses it.

6

Path drawing is performed using values in the workpiece coordinate

system. Coordinates that allow for tool compensation (cutter

compensation, tool length compensation, geometry compensation,

and wear compensation), tool tip control, or the like are not used for

drawing.

7

This function cannot be used with the MANUAL GUIDE i simulator

for the personal computer.

MACHINING SIMULATION (TOOL PATH) (FOR Series

16i/18i/21i)

The path of the tool in a machining program can be drawn without

performing actual machining operation on the machine (machining

simulation). This section is an explanation for Series

16i/18i/21i

model B. In the case of Series 30i, see Section 9.4.

NOTE

1

To perform machining simulation, select the MEM

mode with the mode switch on the machine

operator's panel.

2

If a coordinate system change is specified in the

program during simulation, simulation is performed

without changing the coordinate system.

3

In the drawing during machining, when the

workpiece specifying block is executed, form of a

workpiece is drawn in form of wire frame. Drawing

color of the workpiece can be specified by the

parameter No.14773.

4

When a simulation window is opened, a blank

figure drawing at the last drawing is displayed.

However, if bit 4 of parameter No. 27310 is set to

1, no blank figure is displayed when a simulation

window is opened.

5

Tool path drawing with a multi-path system is

performed only at the selected path for displaying.

And a simulation window is initialized if the

selected path for displaying is changed. So if the

selected path for displaying is changed in

displaying a free blank figure, the drawing is

initialized for a column figure which encloses it.

9.MACHINING SIMULATION AND DRAWING DURING MACHINING

NOTE

6 Path drawing is performed using values in the

workpiece coordinate system. Coordinates that

allow for tool compensation (cutter compensation,

tool length compensation, geometry compensation,

and wear compensation), tool tip control, or the like

are not used for drawing.

7 Simulation cannot be performed in any of control

modes of the high-speed and high-precision

functions (commands for advanced preview

control, AI advanced preview control, AI contour

control, AI nano contour control, high-precision

contour control, AI high-precision contour control,

and AI nano high-precision contour control).

8 In simulation of a program having a sequence of

contiguous small blocks, drawing requires longer

processing time, possibly causing machining time

to become longer than actual machining time.

Animated simulation of a machining operation by a machining

program can be performed without performing actual machining

operation on the machine. This section is an explanation for Series

16i/18i/21i-MODEL B. In the case of Series 30i, see Section 9.5.

NOTE

1 To perform machining simulation, select the MEM

mode with the mode switch on the machine

operator's panel.

2 If a coordinate system change is specified in a

program under simulation, whether to perform

simulation with the same coordinate system or a

changed coordinate system can be chosen using

bit 1 (ACD) of parameter No. 27311. For details,

see Section 9.8.

3 When a program that is composed by repeated

minute line segments like a program outputted by

CAD/CAM is executed, sometimes the speed of

simulation much slows down. In this case, please

set tool motion unit to parameter No. 27323 by dot.

When tool moves over the value of this parameter

on screen, the screen is updated and the speed will

be accelerated. But, if the value of the parameter is

too large, the resolution will decrease.

Notes on Machining Simulation

During the execution of drawing, the system is automatically placed in

the machine locked state. During the execution of drawing, no

machine control signals are output by auxiliary and other functions,

but control signals such as "OP," "STL," "SPL," "RST," and "AL"

may be output. During the execution of drawing, the

drawing-in-progress signal "CKGRP," shown below, is output. If the

control signals that may be output during the execution of drawing

affect machine control, the PMC Ladder program must be modified so

that these signals are ignored, by using the drawing-in-progress signal.

B-63874EN/05

NOTE

1

The data displayed on the machining simulation

screen such as the current position and remaining

travel distance is not automatic operation state

data but is machining simulation data.

2

The machining simulation screen does not display

spindle information and feed information but

displays the next travel distance only.

3

On the machining simulation screen, the remaining

travel distance is 0 at all times.

4

To stop machining simulation, press the [STOP]

soft key. If RESET key is pressed, foreground

operation is reset.

5

If a blank registration command is executed in tool

path drawing during machining simulation, the

blank figure is displayed using a line (wire frame).

Use parameter No. 14773 to specify the display

color of the blank figure.

6

When the simulation window is displayed, the blank

figure data previously displayed is used for

drawing. However, when bit 4 of parameter No.

27310 is set to 1, no blank figure is displayed if the

simulation window is open.

7

In machining simulation performed with a multipath

system, the tool path of the displayed path only is

drawn. If the displayed path is switched during path

drawing, the drawing screen is initialized. So, if the

displayed path is switched when an arbitrary figure

blank is displayed, the blank is initialized to a round

rod figure enclosing the arbitrary figure.

8

If the animated simulation option is not selected, a

blank figure command is ignored, and no blank

figure (wire frame) is displayed.

9

When simulation is started from a midway point,

the modal state of the NC is not always executed

up to the midway point. So, if simulation is started

from a midway point, correct drawing operation

may not be performed.

During machining, animated simulation can be performed for another

program.

The terms related to operation and drawing for tool path drawing

described in Section 9.4 are applicable. See Section 9.4.

With Series

30i MANUAL GUIDE i, machining simulation

(animated) can be performed in the MEM mode and EDIT mode. The

operation for displaying the machining simulation screen in each

mode is the same as for tool path drawing. See Section 9.4.

In order to distinguish the executing state of the program, machining

custom macro program can refer to the following system variable

#3010.

On the 1st page soft keys, you can perform operations related to

execution in machining simulation

(animated). The operations of

[REWIND], [START], [PAUSE], [SINGLE], and [STOP] are the

same as the operations in machining simulation (tool path). For details,

see Subsection 9.2.3.

[INIT]

: Initialize the machined blank used for animation.

[CUTDSP] : Lets you switch between 1/4 workpiece and entire

periphery for rod blanks and drilled rod blanks. Before

starting animated simulation, be sure to switch if

necessary.

[INTERF]

: Lets you select whether to make an interference check

during animated simulation. If an interference check is

enabled, a warning is displayed when the tool tip

collides with a workpiece during rapid traverse, and the

DATA HANDLED DURING MACHINING SIMULATION

(FOR Series 30i)

During machining simulation (background operation), data is handled

as indicated below.

<1>

Parameter

The same parameters are used for machining

simulation and automatic operation.

<2>

Tool compensation value

Data used for machining simulation differs from

Workpiece origin offset value

data used for automatic operation.

Extended workpiece origin offset value

Macro variable

Fixture offset data

<3>

Tool life management data

These data items are not used for machining

Tool number offset data

simulation.

3-dimensional error compensation data

<1> Parameter

The same parameters as used for automatic operation are used for

machining simulation. However, no parameter can be rewritten

in background operation. (If an attempt is made to rewrite a

parameter by programmable parameter input

(G10L50), a

warning (NC statement error (B.G.) is output.)

<2> Tool compensation value, workpiece origin offset value,

extended workpiece origin offset value, macro variable, etc.

Data used for background operation differs from data used for

automatic operation. When background operation is started, the

data for automatic operation is copied to produce data for

background operation. Afterwards, the data for background

operation and the data for automatic operation are handled

separately from each other. So, even when data is rewritten using

G10, for example, background operation and automatic operation

do not affect each other. Note, however, that data rewritten in

background operation is erased without being reflected in the

actual data (foreground data).

<3> Tool life management data, tool number offset data,

3-dimensional error compensation data

These data items are not used for background operation. So, if an

attempt is made to rewrite data by using G10, a warning (NC

statement error (B.G.)) is output.

OPERATION

9.MACHINING SIMULATION AND DRAWING DURING MACHINING

NOTE

6 When the blank registration command for animated

simulation or the spindle switching command G1998

is specified, the modal workpiece coordinate system

is displayed to match the workpiece coordinate

system set with the blank registration command (the

C-axis position is also initialized).

7 If drawing of machining simulation is performed from

an intermediate point of the program, it is performed

as the continuous-state workpiece coordinate system

is same as one of the last simulation.

8 Machining simulation is performed assuming that the

tool tip position (radius of the tool nose or tool radius

center) is at specified workpiece coordinates

(absolute coordinates). So, if the tool tip is not placed

at a specified position, drawing is not performed

correctly. Moreover, drawing is not performed in a

coordinate system where tool compensation (such as

cutter compensation, tool length compensation,

geometry compensation and wear compensation),

tool nose control, and so forth are considered.

9 Rotary C-axis, rotary axis set by parameter No.14717,

always rotates about a blank. And in the case of a

rectangular solid blank, rotary C-axis rotates about

Z-axis on a “WORK ORIGIN” point.

10 Tool drawing is not slant by the rotate angle in

drawing of machining simulation of polar coordinate

interpolation.

In the case of multi-paths T system, G1998 (spindle definition block

for drawing) and G1992 (top of process definition) are as follows.

1)

Parameter No.27311#1(ACD)=1

•

Spindle at which animated simulation is performed is

defined only by G1998 command.

•

Spindle at which animated simulation is performed is the

last commanded by G1998 command at one of paths.

•

If Spindle of G1998 or G1992 commanded at a path is same

as the last commanded by G1998 command, animated

simulation is performed at the path.

2)

Parameter No.27311#1(ACD)=0

•

Spindle at which animated simulation is performed is

defined only by G1998 or G1992 commands.

•

Spindle at which animated simulation is performed is the

last commanded by G1998 or G1992 commands at one of

paths.

•

If Spindle of G1998 or G1992 commanded at a path is same

as the last commanded by G1998 or G1992 commands,

animated simulation is performed at the path.

SETTING OF DATA FOR ANIMATION

When animation can be performed, a blank figure and tool figure must

be set. Such animation data must be set in the DRAWING

DEFINITION block, which is to be entered in a machining program.

To display the window for entering DRAWING DEFINITION data,

press [START] in the soft key menu for editing machining programs.
