MACRO COMPILER/MACRO EXECUTER

Overview

The macro executor function converts custom macros created by machine tool builders to executable
programs, registers them in the FLASH ROM module, and executes them to solve problems as described
below.
NC programs are divided into two types: Programs that are hardly modified after created (programs
created using custom macros) and programs that differ depending on the workpiece (machining
programs). Since different types of programs are processed in the same way, a custom macro may be
destroyed due to a battery failure or operator error.

Features
-

Since the program is stored in executable form program, the execution speed is high. Machine time
is then reduced, and precision is improved.

Since the program is stored in FLASH ROM, there is no lost of data of battery failure or corruption.
Reliability is improved.

Stored programs are not displayed on the program screen, so know-how of the machine tool builders
is kept protected.

Since custom macros are stored in FLASH ROM, the program editing memory can be used
effectively.

The user can call the macro without knowing the stored program. A custom macro can be created
and executed in the program edit memory.

An original screen can be created by using the graphic display or by selecting screens by the soft key.

The machine tool builder can extend the control function by using such functions as machine
program creation and edit control, RS-232C interface control, and PMC data read/write functions.

CHAMFERING AND CORNER ROUNDING

Overview

A chamfering or corner rounding block can automatically be inserted between linear interpolation (G01)
along a single axis and that along a single axis normal to that single axis.
Chamfering or corner rounding is inserted for a command to move the tool along two axes on the plane
determined by the plane selection (G17, G18, or G19) command.

12. PROGRAM COMMAND

Example:

When the A-axis is set as an axis parallel to the basic X-axis (by setting parameter No. 1022 to 5),
the following program performs chamfering between cutting feed along the A-axis and that along
the Z-axis:

G18 A0 Z0

G00 A100.0 Z100.0

G01 A200.0 F100 K30.0

Z200.0

The following program causes an alarm. (Because chamfering is specified in the block to move the
tool along the X-axis, which is not on the selected plane)

G18 A0 Z0

G00 A100.0 Z100.0

G01 X200.0 F100 K30.0

Z200.0

The following program also causes an alarm. (Because the block next to the chamfering command
moves the tool along the X-axis, which is not on the selected plane)

G18 A0 Z0

G00 A100.0 Z100.0

G01 Z200.0 F100 I30.0

X200.0

A radius value is specified at I, J, K, R, and C.

In an incremental programming, use point b in the figure in "Format" as the start point in the block next to
a chamfering or corner R block. That is, specify the distance from point b. Do not specify the distance
from point c.

Example

Limitation

Alarms

In the following cases, an alarm is issued:

Chamfering or corner R is specified in a block for threading (alarm PS0050, “CHF/CNR NOT
ALLOWED IN THRD BLK”).

G01 is not specified in the block next to the G01 block in which chamfering or corner R is specified
(alarm PS0051, “MISSING MOVE AFTER CNR/CHF” or PS0052, “CODE IS NOT G01 AFTER
CHF/CNR”).

An axis which is not on the selected plane is specified as a move axis in the block in which
chamfering or corner R is specified or the next block (alarm PS0051 or PS0052).

12. PROGRAM COMMAND

B-64693EN-1/01

A plane selection command (G17, G18, or G19) is specified in the block next to the block in which
chamfering or corner R is specified (alarm PS0051).

When bit 4 (CCR) of parameter No. 3405 is set to 0 (to specify chamfering at I, J, or K), two or
more of I, J, K, and R are specified in G01 (alarm PS0053, “TOO MANY ADDRESS
COMMANDS”).

Chamfering or corner R is specified in the G01 block to move the tool along more than one axis
(alarm PS0054, “NO TAPER ALLOWED AFTER CHF/CNR”).

The travel distance along an axis specified in the block in which chamfering or corner R is specified
is smaller than the amount of chamfering or corner R (alarm PS0055, “MISSING MOVE VALUE
IN CHF/CNR”). (See the Fig. 12.19 (a).)

10) In a shape program in the multiple repetitive canned cycle (G70, G71, G72, or G73), a command for

the chamfering or corner R in the last block is terminated in the middle (alarm PS0069, ”LAST
BLOCK OF SHAPE PROGRAM IS AN ILLEGAL COMMAND”).

Single block operation

When the block in which chamfering or corner R is specified is executed in the single block mode,
operation continues to the end point of the inserted chamfering or corner R block and the machine stops
in the feed hold mode at the end point. When bit 0 (SBC) of parameter No. 5105 is set to 1, the machine
stops in the feed hold mode also at the start point of the inserted chamfering or corner R block.

Macro executer

Chamfering and corner rounding specified in the execution macro is disabled.

Cutter compensation or tool nose radius compensation

When applying cutter or tool nose radius compensation, note the following points:

1.

If the amount of inner chamfering or corner R is too small as compared with compensation and
cutting is generated, alarm PS0041, “INTERFERENCE IN CUTTER COMPENSATION” is issued.
(See the Fig. 12.19 (c).)

(The solid line indicates the programmed path after chamfering. The
dotted line indicates the tool center path or tool nose radius center path.)

Fig. 12.19 (c)

2. A function is available which intentionally changes the compensation direction by specifying the I, J,

or K command in the G01 block in the cutter or tool nose radius compensation mode (see the
explanations of cutter or tool nose radius compensation). To use this function when the chamfering
and corner R function is used, set bit 4 (CCR) of parameter No. 3405 to 1 so that I, J, and K are not
used for specifying chamfering. Operation to be performed under each condition is explained below.

(1) When the chamfering and corner R function is not used

In the G01 block in the cutter or tool nose radius compensation mode, the cutter or tool nose
radius compensation direction can be specified at address I, J, or K.

No chamfering is performed.

(2) When the chamfering and corner R function is used

(2-1) When bit 4 (CCR) of parameter No. 3405 is set to 0

In the G01 block in the cutter or tool nose radius compensation mode, chamfering can be
specified at address I, J, or K. Corner R can also be specified at address R.

The cutter or tool nose radius compensation direction cannot be specified.

(2-2) When bit 4 (CCR) of parameter No. 3405 is set to 1

In the G01 block in the cutter or tool nose radius compensation mode, the cutter or tool
nose radius compensation direction can be specified at address I, J, or K.

Chamfering or corner R can also be specified at address C or R.

NOTE

The chamfering and corner R function and direct drawing dimension programming
function cannot be used simultaneously. When bit 0 (CRD) of parameter No. 3453
is set to 0, chamfering and corner R is enabled. (At this time, direct drawing
dimension programming is disabled.)
