2000 Series Universal Cylindrical Grinder Operating Manual
{{@672}}
Introduction
The 2000 Series Universal Cylindrical Grinder control is a two-axis CNC system for OD/ID grinders.
The system includes standard dressing and grinding macros for common straight, tapered and profile geometries with a more simplified G code program. With its familiar windows interface, intuitive graphics, and user friendly layout, the system is easy to learn. Allowing you to have the machine operational almost immediately
The control also accepts standard Fanuc standard G-code, as well as Fanuc Macro B programming compatibility, giving operators virtually unlimited capabilities for writing their own custom programs and macros.
This manual gives the process for basic operation of the 2000 Series Cylindrical Grinder control including a summary of the different features of the tabs and additional screens.
To open the control software double-click on the profile icon on the desktop.
Screen Navigation
Run Page
The run page contains the necessary features for operating the machine. The left side of the screen contains buttons for loading, editing, and running programs as well as the live tool path window to see the path the machine will take when the program is run.
The center of the screen contains information about machine status. The feedrate, wheel head RPM, and workhead spindle RPM can be modified on the fly by typing a new value in the blue box.
On the right side of the screen is a dashboard that can be configured with any number of widgets based on the operator's preferences (See the Series 2000 User Manual). Seen in the example above is the tool wear offset input window which can be used to make slight adjustments to the part diameter, the part offset table (Part Correction Offset) which, when multiple features are being ground on the part, can be used in conjunction with an "E" variable in the program to allow adjustments to each feature individually.
Conversational Page
The conversational screen is used to quickly and easily create new grinding and dressing programs without manually writing gcode. A program consists of a set of cycles that are included in the job. The cycles can be added to the job in any order and rearranged or removed as needed. Adding a cycle is a matter of selecting the type of cycle, inputting the dimensional data, and pressing Add to Job. Once all cycles are correct, the Post button will load the job for running.
Grinder Setup
The grinder setup screen is used to set up the grinding wheels, dresser options, and safety clearances.
Wheel Head Setup
This page is for setting up wheel head parameters for the active wheel. These parameters affect how the cycles run and how the wheel is dressed.
Dresser Setup
This page is for setting up the dresser diamonds on the machine. There are three types of diamonds supported here:
- Profile dresser: used for dressing circumference and or one side of wheel, as well as user developed wheel profiles.
- Universal dressers: two dressers are used for dressing forms that exceed 90 degrees of travel into or around the wheel that cannot be done with a single dresser. For example, a full radius dressed into or onto the circumference of the wheel, or radii or profiles on both corners of the wheel.
- Straight dressers: used for straight dressing of all three surfaces of the wheel.
Safety Clearances
This page sets the distances between wheel, part, and diamond that are considered safe. These should be configured before running parts or dressing a wheel.
Rotary Dresser
If the machine has a rotary dresser, it's parameters are set on this page.
Calibrate
The calibrate screen is used for calibrating the grinding wheel to the part and adjusting the part size. The axes are brought into position, touching the part, and taught that position. The part is then measured at that position, and the position is updated to adjust for any discrepancy.
Fixtures
The fixtures screen is used for setting fixture, machine, and or work offsets.
Service
The service screen gives access to machine settings and diagnostics. It also contains a second configurable dashboard that can be setup to user preferences.
Maintenance
The service screen is used for control set up, diagnostics, and getting remote help from the support team.
Machine I/O
This page allows the operator to see the state of all configured signals and I/O that are in use on the machine.

Grinding Cycles
Dressing Cycles
Positioning to Dress
When a dressing cycle is called the machine will always follow the following path from the part to the dresser, in order to avoid collisions with the part and the diamond.
G251: Dress Taper Face 1, Left
The G251 cycle dresses a taper on the left face. It can increment in on just the X axis, just the Z axis, or on both axes.
The size of the phase height, relief height, and relief angle are all set on the Wheel Head Setup page.
Parameters:
-
- D: The infeed increment to remove from the wheel on each pass.
- E: The number of passes to make across the wheel.
- F: The feedrate to use while dressing wheel.
- I: The height of the taper to put on the wheel (X direction).
- J: The angle of the taper to put on the wheel.
- K: The length of the taper to put on the wheel (Z direction).
- [M]: Passing in a 1 to the M parameter will force dressing. If the parameter is not given and the number of parts per dressing has not been met, then dressing will be skipped.
- [R]: Passing in a 1 to the R parameter will skip setting tool offsets and wheel sizes.
- [Q]: Selects the compensation direction used during the dressing cycles. By default, the compensation is only in the X direction, changing the diameter of the wheel. If a 1 is passed to the Q parameter, then compensation will be in the Z direction, narrowing the wheel. If a 2 is passed to the Q parameter, then compensation will be in the X and Z directions, changing the diameter and narrowing the wheel.
Only two of the parameters I, J, K are required.

% (EOB)G287: Plunge Infeed Grind
G287 is used in conjunction with G276 for two axis plunge grinding. G276 defines the start point of the grind and G287 defines the ending position of the plunge grind.
Parameters:
-
- [X]: The final X diameter to plunge to
- [Z]: The final Z position to plunge to
- [A]: The allowance to leave on final grind position in both X and Z axes. Default is 0.

% (EOB)G288: Handwheel Infeed Cycle
This cycle allows the operator to manually jog the X axis with the MPG handwheel or operator panel while the Z axis maintains the motion defined by G271 and G272. The cycle will continue until the operator presses Cycle Start or stops the program. Jogging on all axes other than X will be disabled during this cycle. There are no parameters for this cycle.
Upon pressing Cycle Start, the operator will be presented with a confirmation dialog on the control screen that they wish to end the handwheel infeed cycle. If they select 'No', the cycle will continue until they choose to end it again. If they select 'Yes', then the Z axis will continue its cycling until it reaches swing position 1, defined by G271, and then the main program will continue. While the axis is returning to swing position 1, a progress dialog will be displayed on the control screen.
If the operator presses Feedhold during the handwheel cycle, the Z axis will continue until it reaches the next swing position, and then stop there until Cycle Start is pressed or the program is stopped.
If the operator presses Cycle Stop while this cycle is running, the Z axis will stop without returning to either swing position. To control the distance that the axis takes to stop, set the parameter in MachMotion Configuration for Reciprocating Axis - Z Axis - Cycle Stop Distance.

% (EOB)G289: Relieve
G289 performs a retract in X and Z axes. The cycle preceding G289 determines which axis and the direction of the retract. If G289 follows G281, G282, G283, G284, or G288, then the retract will be a positive X axis move. If G289 follows G285, then the retract will be a positive Z axis move. If G289 follows G286, then the retract will be a negative X axis move.
Parameters:
-
- [W]: Relieve amount
- [F]: Feedrate

G230: Active Flagging with Probe
Flagging is used to find a shoulder on the part. When G230 is called the X axis will move to the X swivel position followed by the Z axis. The flagging slide will extend and then the Z axis will move to the Z start position followed by the X axis. The probing cycle will start with the Z axis moving at the calibrated fast feedrate. When the shoulder is detected, the probe will back off and probe again at the calibrated slow feedrate. The K parameter will be written to the current fixture offset (which defaults to G54) and the fixture table will be saved. The probe will move back to the start position, then back to the swivel position, and then retract.
Parameters:
-
- X: The start position X will rapid to before starting the flagging routine, after flag is extended.
- Z: The start position Z will rapid to before starting the flagging routine, after flag is extended.
- W: The distance Z will move searching for a shoulder, which can be positive or negative to indicate direction of travel.
- [E]: Selects between flagging the part and calibrating the probe. E1 will calibrate the probe. Defaults to 0 for normal flagging.
- [K]: The Z position used to calibrate the shoulder. Default is 0.
- [R]: Indicates if to retract the probe at the end of cycle. A value of 1 will leave the probe extended at the end of the cycle. Default is 0 to retract the probe.
