Berthiez BM160
with Centroid T400 Control

Daily Operation

Startup

  1. Switch on main switch, on cabinet in back
  2. Wait for console to boot and display "Home not set"
  3. Release Emergency Stop
  4. Press the HYDRAULIC PUMP key (Aux1) to start the Hydraulic system
  5. Press CYCLE START to find and set machine home
The Machine Home position is fully X+ (carriage right) and Z+ (ram up).

The control starts up in Incremental jog mode. In order to jog the axes in continuous movement, you need to press the INCR/CONT key to switch from incremental to continuous jog mode.

Idle Periods

  1. Press Emergency Stop to remove power from the servos and shut down the hydraulics.
  2. To resume normal operation, release Emergency Stop, then press the HYDRAULIC PUMP key to restart the hydraulics.

Shut Down

  1. Optionally, press F10/Shutdown, F1/Park to move the carriage back near the machine home position. This will save time on the next startup and homing sequence.
  2. Press Emergency Stop
  3. Press F10/Shutdown, F2/PowerOff
  4. Wait for console display to go fully blank (about 15 seconds)
  5. Switch off main switch, on cabinet in back

Tool Setting

I recommend measuring tool X offsets relative to an imaginary tool nose, and Z offsets relative to an actual tool.

The procedure for this may be found at http://www.cncsnw.com/OLEL.htm, as "Method 3". However, on this machine the arbitrary X axis position set at machine home with no tool offset should be comparable to the maximum swing (e.g. 144").

Turret Controls

You can rotate the tool turret manually or with an M function.

Indexing by tool number is not provided.

Rotate tool turret. You must hold the key down until the turret stops at the next position.
M6 Index to next turret position.

Note: as of November 2009, the tool turret is not operational

Table Rotation Controls

You can control table ("spindle") rotation speed and direction manually with jog panel keys, or automatically with program codes.

Note that table direction is judged by tool direction. "Forward" or "Clockwise" is the direction you would run a standard twist drill. This is opposite how you would ordinarily judge "clockwise" and "counterclockwise" if you were looking down at the face of the table.

The spindle must be in Auto mode in order to use programmed M and S codes. The spindle must be in Manual mode in order to use the jog panel keys.

Switch between Auto and Manual control modes.

In manual mode, you can control operation and direction with these keys:

Select spindle forward (CW tool)
Select spindle reverse (CCW tool)
Start spindle
Stop spindle

In Auto mode, you can control operation and direction with these codes:

M3 Start spindle forward (CW tool)
M4 Start spindle reverse (CCW tool)
M5 Stop spindle
Snnn Set speed to nnn RPM or SFM

In constant-RPM mode (G97) the S code specifies RPM. In constant surface speed mode (G96) the S code specifies SFM (surface feet per minute).

In either mode, you can further control speed with these keys:

Increase speed
Set speed to 100% of programmed speed (Auto mode) or to half of maximum speed (Manual mode)
Decrease speed

Table Jog for Setup

With the table stopped, you can momentarily jog it around at low speed with these keys:

Jog table CW (looking down at table)
Jog table CCW (looking down at table)

Note that these two keys show rotation from the operator's viewpoint, rather than reflecting tool direction.

Gear Shifters

The machine has a hydraulically shifted two-speed gearbox.

You can shift gears manually with jog panel keys, or automatically with M functions:

Shift to high range (9-140 RPM)
M42
Shift to low range (2-33 RPM)
M41

Overarm Jogging

Overarm movement is powered by a 7.5HP motor on top of the column, which turns the elevation screw through a right-angle gearbox.

You can jog the overarm up and down manually whenever the hydraulic system is running and no program cycle is active. The control will automatically release the hydraulic clamps when you press a jog key, and will automatically reclamp when you release the jog key. Before movement starts there will be a short delay in order to give the clamps time to release.

Jog overarm up
Jog overarm down

Table Base Jogging

The table base is moved by a hydraulic piston. Movement is aided by a pneumatic "float" system which directs air pressure underneath the table base.

You can jog the table base left and right manually whenever the hydraulic system is running, the table is not turning, and no program cycle is active. The control will automatically release the clamps when you press a jog key, and will automatically reclamp when you release the key. Before movement starts there will be a short delay while the control waits for the pressure switches to indicate the clamps are released.

Jog table base left
Jog table base right

Work Lights

The work lights will come on automatically when the control starts up. You can switch the lights off and on as needed using the jog panel key:

Switch work lights on and off

Overarm Lube System

The PLC will power the Bijur lube system whenever a program cycle, or the MDI prompt, is active.

Errors, Faults and Warnings

The PLC program can generate the following fault messages, in addition to those listed in the Centroid operator's manual.

You can use the PLC Diagnostic display on the console to view the PLC input and memory locations mentioned with some of the following fault conditions. At the control's main screen, press Alt-I to activate the PLC Diagnostic display. Press Alt-I again to dismiss it.

The Diagnostic display shows four rows of red and green dots: the first row shows PLC inputs 1 through 80; the second row PLC outputs 1 through 80; the third row PLC memory bits 1 through 80; and the fourth row PLC program stages 1 through 80.

You can use the arrow keys to move a highlight box over any of these locations. The name of the highlighted location will be displayed at the bottom left.

"436 NOPTIC1 fault"
