Ok you Mazak guru's?

[MultiAxGod]

I need to dwell when locking up the steady rest. If programming in EIA is it still as simple as G04 P500.? or does it need the value as X. I can't find it in the book for dwelling. EIA information is extremely limited.

From our eia book:

code:

---

8 DWELL FUNCTIONS

The start of execution of the next block can be delayed using a G04 command. Depending on

the respective feed mode (G94: feed per minute, G95: feed per revolution), the type of G04

command value (specification of time or number of revolutions) can automatically be identified.

In addition, the remaining time of dwell can be nullified by a multi-step skip function.

8-1 Dwell Command in Time: (G94) G04

1. Function and purpose

Setting command G04 in the feed-per-minute mode (command G94) delays the start of

execution of the next block for the specified time.

2. Programming format

G94 G04 X_

or

G94 G04 P_

Data can be set in 0.001 seconds.

For address P, the decimal point is not available. The part after the decimal point will be ignored.

3. Detailed description

1. The setting range for dwell time is as follows:

Unit of data setting Range for address X Range for address P

0.01/0.001 mm 0.001 to 99999.999 (sec) 1 to 99999999 (× 0.001 sec)

0.0001 inches 0.001 to 99999.999 (sec) 1 to 99999999 (× 0.001 sec)

2. The count for the dwell command which is preceded by a block with cutting-feed command

is not started until the movement of the preceding block has been brought to a complete

stop.

MEP054

Next block

Dwell time

(5 sec)

Dwell command

Cutting command in

the preceding block

If the dwell command is given in one block together with an M-, S- T- or B-code, the dwell

count and the execution of the respective code will be started at the same time.

3. The dwell function is valid during the interlock mode.

4. The dwell function is also valid during machine lock. It can be, when required, immediately

terminated using bit 4 of user parameter F93.

8 DWELL FUNCTIONS

8-2

4. Sample programs

- When data is to be set in 0.01 mm, 0.001 mm or 0.0001 inches:

G04 X500 Dwell time = 0.5 sec

G04 X5000 Dwell time = 5.0 sec

G04 X5. Dwell time = 5.0 sec

G04 P5000 Dwell time = 5.0 sec

G04 P12.345 Dwell time = 0.012 sec

- When data is to be set in 0.0001 inches and included before G04:

X5. G04 Dwell time = 50 sec (Equivalent to X50000G04.)

8-2 Dwell Command in Number of Revolutions: (G95) G04

1. Function and purpose

Setting command G04 in the feed-per-revolution mode (command G95) suspends the start of

execution of the next block until the spindle has rotated the specified number of revolutions.

2. Programming format

G95 G04 X_

or

G95 G04 P_

Data can be set in 0.001 revolutions.

For address P, the decimal point is not available. The part after the decimal point will be ignored.

3. Detailed description

1. The setting range for number of dwell revolutions is as follows:

Unit of data setting Range for address X Range for address P

0.01/0.001 mm 0.001 to 99999.999 (rev) 1 to 99999999 (× 0.001 rev)

0.0001 inches 0.001 to 99999.999 (rev) 1 to 99999999 (× 0.001 rev)

2. The count for the dwell command which is preceded by a block with cutting-feed command

is not started until the movement of the preceding block has been brought to a complete

stop.

Next block

Number of

revolutions

for dwell

(12.345 rev)

Dwell command

Cutting command in

the preceding block

MEP054

If the dwell command is given in one block together with an M-, S- T- or B-code, the dwell

count and the execution of the respective code will be started at the same time.

DWELL FUNCTIONS 8

8-3

3. The dwell function is valid during the interlock mode. That is, dwell is executed even during

the interlock mode.

4. The dwell function is also valid during machine lock.

5. During rest of the spindle, dwell count is also halted. When the spindle restarts rotating,

dwell count will also restart.

6. If the bit 2 of parameter F92 is set to 1, dwell command value is always processed in time

specification.

Send me an email and I will send you a pdf of these pages.

Thanks Ron, will send it in a second. I wonder why we don;t have these books here. we have 4 Mazaks, but only have operating manual, parameter list and the programming manual onl has 6 pages in it?

[MultiAxGod]

Looking through here at my G-Code list, it doesn't even show G94 or G95?

[Tim Johnson]

For 5 seconds G98 G04 P5000 or G98 G04 (X5. or X5000). For 5 revolutions G99 G04 P5000 or G99 G05 (X5. or X5000). On our T+ control if parameter P10 bit2 is set to 1 dwell is always set in seconds regardless of G98 or G99 mode.

You have mail.

Got it Tim and Ron. Had to use X, for some reason it just skipped over the P?

[MultiAxGod]

Thanks, Ron. You've got mail!
