M19 Orient spindle
Haas NGC M-code · Mill, Lathe
On mills: Orient spindle
Stops the spindle at a fixed angle. P or R can set the angle. Used for boring bar shift, probes and setup.
Format
M19 [P] [R]
Addresses
| Address | What it does |
|---|---|
P | Orient angle in whole degrees |
R | Orient angle in degrees with decimals |
How it works
Not modal. Acts once on the line where it is commanded.
Example program
M05 (SPINDLE STOP)
M19 R90. (ORIENT THE SPINDLE TO 90 DEG)
M00 (CHECK BORING BAR TIP DIRECTION)
M19 R90. (ORIENT THE SPINDLE TO 90 DEG)
M00 (CHECK BORING BAR TIP DIRECTION)
Example is in inch. Check offsets and clearances first.
Watch out for
- The spindle orient angle option may be needed to use P or R.
- Plain M19 goes to the factory orient position.
On lathes: Orient spindle
Orients the main spindle to a fixed angle. P gives whole degrees and R gives up to two decimal places. Without the option it orients to zero only.
Format
M19 [P] [R]
Addresses
| Address | What it does |
|---|---|
P | Angle in whole degrees, 0 to 360 |
R | Angle with two decimals, 0 to 360 |
How it works
Non-modal.
Example program
M05 (SPINDLE STOP)
M19 P90 (ORIENT SPINDLE TO 90 DEGREES)
M14 (BRAKE ON)
M19 P90 (ORIENT SPINDLE TO 90 DEGREES)
M14 (BRAKE ON)
Example is in inch. Check offsets and clearances first.
Watch out for
- A negative value is ignored and the spindle goes to 0 degrees.
- Heavy or long parts may not orient well. Call Haas applications for odd setups.
- Under G14, M19 orients the secondary spindle.
