Giddings & Lewis 450-Series Table-Type HBM
with Centroid M400 Control

Overview

The machine is a four-axis horizontal boring mill. It can operate in either a horizontal format, or in a vertical format using a right-angle head attached to the spindle face.

In the horizontal milling format, axis movement is as follows:

XTable left/right
YHead up/down
ZBar in/out
WSaddle out/in

In the vertical milling format, axis movement is as follows:

XTable left/right
YSaddle in/out
ZHead up/down

Startup

  1. Switch on the disconnect switch on the power cabinet
  2. Press and hold the power button on the uninterruptible power supply (UPS) in the middle cabinet, for one second. You should hear a long beep followed by a short beep for confirmation.
  3. Wait for console to boot and display "Home not set"
  4. Release Emergency Stop
  5. Press CYCLE START to find and set machine home

The Machine Home position is with the table fully to the left; head all the way up; saddle away from the column; and, if in the horizontal format, bar fully retracted.

Idle Periods

  1. Press Emergency Stop to shut off the hydraulic pump and remove power from the servo and spindle drives.
    The headstock scavenger pump will continue to run for several minutes to return oil from the head
  2. To resume normal operation, release Emergency Stop.

Shut Down

  1. Press F10/Shutdown
  2. Optionally, press F1/Park to move the axes back near the machine home position. This will save time on the next startup and homing sequence.
  3. Press Emergency Stop
  4. Press F2/PowerOff
  5. Wait for CNC console display to go fully blank (about 15 seconds).
  6. Switch off the disconnect switch on the power cabinet
  7. Press and hold the power button on the uninterruptible power supply (UPS) in the middle cabinet, for one second. You should hear a long beep followed by two short beeps for confirmation.

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.

Changing Machine Format

The switch between horizontal milling and vertical milling formats is accomplished by swapping control configuration and parameter values, and of course by installing or removing the right-angle head.

After swapping configuration and parameter files, the control must be shut down, powered off, and powered back up in order for the change to take effect.

It will be easier to install and remove the right-angle head while the control is configured for horizontal milling operation. Therefore you should install the right-angle head just before switching the control from horizontal to vertical; and you should remove the right-angle head after switching the control back from vertical to horizontal.

This is because in horizontal mode you can control the bar, as the Z axis. In vertical mode you cannot move the bar.

To Switch to Vertical Mode

  1. Install the right-angle head (see below)
  2. If you wish, jog the X, Y and W axes close to their home positions.
    Do not use the Park option on the Shutdown screen, as that would retract the bar
  3. Press F7/Utility
  4. Press F2/Restore Report
  5. Arrow down to the [VerticalHorizontalSwitch] folder and press Enter
  6. Arrow down to report_0921180661_vertical.zip
  7. Press F10/Accept
  8. When prompted, shut down; power off; wait 30 seconds; and power back up.

To Switch to Horizontal Mode

  1. If you wish, press F10/Shutdown, then F1/Park to move the axes back near their home positions.
  2. Return to the main screen and Press F7/Utility
  3. Press F2/Restore Report
  4. Arrow down to the [VerticalHorizontalSwitch] folder and press Enter
  5. Arrow down to report_0921180661_horizontal.zip
  6. Press F10/Accept
  7. When prompted, shut down; power off; wait 30 seconds; and power back up.
  8. Once started up in horizontal mode, release Emergency Stop; start the hydraulic system; and press Cycle Start to home the machine.
  9. Remove the right-angle head (see below)

Installing the Right-angle Head

  1. Jog the head down to a convenient level
  2. Retract the bar (in horizontal mode, press Tool Check)
  3. Remove the drive dogs from the spindle nose
  4. Jog the saddle in close to the column, so that the right-angle
    head will be over the work table as it is moved into position.
  5. Move the right-angle head onto the spindle face and install the four hex-head screws. Torque to __ ft-lbs.
  6. Press Alt-D to show Machine coordinates on the control's DRO display
  7. Jog the bar out (Z axis, minus direction) to about -18.0 inches
  8. Remove the access plug from the side of the right-angle head
  9. Using the MPG handwheel pendant (Z axis, x10 increment), move the
    bar until the spindle nose is nearly touching the drive face in
    the right-angle head.
  10. Turn the spindle of the right-angle head by hand until its keys line
    up with the notches in the spindle face (where the drive dogs were removed)
  11. Once aligned, use the MPG handwheel to jog Z the rest of the way to -19.63 inches.
  12. Reinstall the access plug
  13. Change the control configuration and parameters over to vertical mode (see above)

Removing the Right-angle Head

  1. Change the control configuration and parameters over to horizontal mode (see above)
  2. Jog the head down to a convenient level
  3. Jog the saddle in close to the column, so that the right-angle
    head will be over the work table as it is removed.
  4. Support the right-angle head with the overhead crane
  5. Remove the four hex-head screws
  6. Remove the right-angle head and set it on its pallet
  7. Reinstall the drive dogs in the spindle nose

Work Light

The work light will come on automatically when the machine is powered up.

You can turn the light off and on by pressing the work light key on the jog panel.

Spindle Rotation Controls

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

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)
Select spindle reverse (CCW)
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

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

Gear Shifters

The machine has a hydraulically shifted 4-speed gearbox.

Gear shifting is always done with M functions, either in a CNC program or at the MDI prompt:

M44

High range(1251-3150 RPM)
M43 Medium-high range(481-1250 RPM)
M42 Medium-low range(191-480 RPM)
M41 Low range(1-190 RPM)
M49 Shift to best range for programmed RPM

In automatic operation, the M3 and M4 codes call M49 at every spindle start, automatically shifting ranges as needed.

You only need to enter M41 - M44 for manual operations.

M41 - M44 require that spindle control be in Auto mode. For use in Manual mode, switch to Auto; run the gear shift M function; and switch back to Manual.

In manual operations, it is possible to run slower than the minimum for each range listed above. For example, the minimum possible speed in high range is about 60 RPM. Thus extra shifting can be avoided, as long as full torque is not required.

You can take the spindle out of gear using the Aux4 key on the jog panel:

Free spindle (shift to neutral)

Axis Way Lube System

The control will automatically operate the way lube pump any time the hydraulic pump is running. The way lube system will not operate when the machine is in an emergency stop or fault condition.

The control will direct way lube to the X, Y, and/or W axes whenever that axis is moving, whether via an automatic program cycle or manual jogging.

If the control is directing way lube to an axis, but the lube pressure switch on that axis fails to show pressure for the time specified in Parameter 953 (in milliseconds), then a fault will be triggered.

If the lube pump itself fails to build output pressure within the time specified in Parameter 954 (in milliseconds), then a fault will be triggered.

G28 Return Point

Most CNC programs will return the Z axis to the G28 return point (return point #1) at the start and end of a job. The control will also move Z to that position at any M6 tool change code, any M25 Z-to-home code, or any press of the Tool Check key.

By default, the Z position for the G28 return point is machine zero, which is fully retracted (in horizontal mode) or all the way up (in vertical mode).

If tooling temporarily prohibits fully retracting the quill; or you want to save time by not fully raising the head, you can change the Z position for G28. To do so:

  1. Press F1/Setup
  2. Press F1/Part
  3. Press F9/WCS
  4. Press F1/Return
  5. Use the arrow keys to select the Z axis line (third line down) of the first return point (the G28 position).
  6. Enter zero (0.0) if you want the quill to retract all the way up to its machine home position. Enter a negative number if you want it to stop farther out.
    For example, in horizontal mode, if you enter -6.0 for the G28 position on the Z axis then the quill will stop while still extended six inches from its machine home for each tool change.
    In vertical mode, if you enter -60.0 for the G28 position on the Z axis then the head will return to a point five feet down from the top of the column.
  7. Press F10/Save
  8. Press ESC three times to return to the main screen

Troubleshooting

Fault, Error and Warning Messages

Any time the control cannot complete its tasks normally, it will display a message in the scrolling message box, in the upper right corner of the screen, explaining what went wrong. You can use the mouse to scroll up (back) in the message box to view the most recent 10 or so messages.

You can view older messages in the error message log, accessible from the F7/Utility menu:

  1. Press F7 for Utility
  2. Press F9 for Logs
  3. Press F1 for Errors
  4. Use PgUp and PgDn as needed to scroll through the pages of messages
  5. Press ESC three times to return to the control's main screen
Note that, in the log display, messages are shown in reverse order (newest at the top).

Most common messages are described in Chapter 15 of the Centroid M-Series Operator's Manual.

The machine-specific PLC program can generate several of its own fault, error and warning messages, in addition to those listed in the Centroid operator's manual. The machine-specific messages are listed later in this section.

PLC Diagnostic Display

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

Each page of 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 in the center of the screen below the red and green dots.

For example, in the illustration above the highlight box is on Output #42: The dot below the 2, to the right of the superscript 4, on the second line.

Below the four rows of bit status information are ten numeric ("word") variable values, labeled W1 through W10. Some of these variables also hold useful status information, described with the error and fault conditions to follow.

There are multiple pages of Diagnostic data. With the Alt-I diagnostic display showing, you can use the F12 and F11 keys to scroll right and left. For example, pressing F12 once will shift to the page showing inputs and outputs 81 through 160, and word variables W11 through W20.

Clearing Faults

Messages with 9000-series message numbers are Faults. After resolving the problem, you must press and release the Emergency Stop button to clear a Fault.

Messages with 8000-series message numbers are Errors. Errors will cancel the program cycle and stop the spindle and coolant, but they do not then need to be explicitly reset.

Messages with 5000-series and 2000-series message numbers are Warnings and Informational Messages. They do not cancel the cycle or require any action to reset.

Opening the Control Cabinet Doors

In some cases, it will be necessary to open the control cabinet doors while power is on. For example, servo drive and spindle drive fault conditions can be more readily identified using the codes displayed on, or stored in, the drive units themselves.

WARNING: Use appropriate caution when working in the control cabinets while power is on. Lethal voltages, up to 480VAC and 700VDC, are present on many components.

The left and center doors are mechanically interlocked with the right-hand door. They can only be opened while the right-hand door is open.

To open the right-hand control cabinet door while power is OFF:

  1. Using a wide blade screwdriver, turn the slotted lock in the black door handle counterclockwise, and hold it there
  2. Pull the trigger on the back of the black door handle
  3. Turn the black door handle clockwise (left) to horizontal
  4. Push in on the power switch handle (to its RESET position)

To open the right-hand control cabinet door while power is ON:

  1. Using a wide blade screwdriver, turn the slotted lock in the black door handle counterclockwise, and hold it there
  2. Pull the trigger on the back of the black door handle
  3. Turn the black door handle clockwise (left) to horizontal
  4. Using a blade screwdriver, turn the release catch on the right side of the power switch handle base.

To open the center or left-hand control cabinet door:

  1. Open the right-hand door
  2. Pull the trigger on the back of the door handle

"9030 SPINDLE FAULT!"

The GS4 spindle drive (VFD) is reporting a fault condition.

This may occur if emergency stop is pressed, and then released within less than five seconds. In this case the safety relay (SR1) does not have time to reset, and so does not close again when emergency stop is released. Press emergency stop; wait at least five seconds; then release emergency stop.

Other spindle faults may result from over-voltage while decelerating, or from overload during spindle reversal (e.g. in a tapping cycle).

If the cause is not immediately evident, then check the LCD display on the spindle drive itself, in the rightmost section of the cabinet.

You can review past drive fault conditions using the GS4 drive's parameters menu. The six most recent fault codes are in parameters P11.04 through P11.09. See chapters 3 and 4 of the GS4 drive manual.

Updating Format-Switching File Sets

The report_0921180661_vertical.zip and report_0921180661_horizontal.zip file sets that are restored when switching machining formats contain the following files:

cncm.prm.xmlMachine ParametersServo drive and encoder mappings, format selector
cncmcfg.xmlMachine ConfigurationAxis labels, drive ratios, backlash compensation, etc.
cncm.wcsWork Coordinate SystemsAxis travel limits and G28 return points
homelog.txtRecord of axis home-search distancesNeeded because Y and Z are different physical axes
scale_settings.xmlLinear scale feedback settingsNeeded because Y and Z are different physical axes, using different scales
report_*.txtHuman-readable record of configuration valuesFor reference only, has no effect on operation

Because these files in the control are replaced with the archived files every time you switch between horizontal and vertical formats, any changes that you might have made in Parameters, Configuration, Work Coordinate Systems, or logged homing distances will be lost on the next format switch.

If there is a need to make changes in any of these areas, and have those changes preserved in the future, then you will need to update the archive file(s) that are used in format switching.

To update one of the archive file sets:

  1. Switch the machine to the desired format
  2. Make the needed change(s) to Parameters, Configuration, etc.
  3. At the main screen, press F7/Utility
  4. Press F7/Create Report
  5. Arrow down to the [VerticalHorizontalSwitch] folder
  6. Press F10/Accept. This will create a new report file in the folder.
  7. Launch the Windows File Explorer (e.g. press the Start Menu key, then click on the file folder icon in the taskbar)
  8. Browse to the c:\cncm\VerticalHorizontalSwitch folder
  9. Identify the new report*.zip file. It will be the one with a date/time code instead of the word "horizontal" or "vertical"
  10. Open that zip file (e.g. by double-clicking on it)
  11. Delete all the files from within that zip file, except for cncm.prm.xml, cncm.wcs, cncmcfg.xml, homelog.txt, scale_settings.xml, and the newest report_*.txt.
  12. Go back up to view the contents of the c:\cncm\VerticalHorizontalSwitch folder
  13. Delete the old archive file for the current format (i.e., either report_0921180661_vertical.zip or report_0921180661_horizontal.zip).
  14. Rename your new, stripped-down report file to the archive name you just deleted.

If appropriate, switch formats and repeat the above procedure for the other format.
