2000 Series Universal Cylindrical Grinder Operating Manual
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 pages and additional screens.
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.
The wheel head will be adjusted as a percentage of the RPM you set in the Grinder setup>Wheel Head Setup screen. (Wheel RPM value) See Wheel head Setup below for more information.
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 page 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.
Measuring Devices
The Measuring Devices page is used view, setup and calibrate the measuring devices that are enabled on the machine.
Calibrate
The calibrate page 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.
Operations
X Axis Direction
External OD
When grinding External the Grind Wheel will normally be on the far side of centerline away from the operator. All diameters are entered in the positive space starting from a larger diameter for the start and ending with a smaller diameter.
Internal ID
When grinding Internal the Grind Wheel will normally be on the same side of centerline as the operator. All diameters are entered in the negative space starting from a smaller negative diameter for the start and ending with a larger negative diameter.
Before Running A Part
Before running parts on the control, be sure the following steps have happened after starting the control software:
- Machine is homed
- Wheel selection is correct
- Safety clearance positions have been taught
- Dresser diamond positions have been taught
- Wheel has been rough dressed
- Wheel has been calibrated to the part
- Flagging device has been calibrated to the wheel
Homing Machine
Most machines are configured with a Enable and Home dialog that will be shown on startup.
Press the Cycle Start button on the dialog or the Cycle Start button on the operator panel. The machine will enable the servos and home to the switches.
If for some reason this dialog is not shown you can manual enable the machine by pressing Reset and then navigate to the Service page.
Home each axis individually or press Home All to home all axes.
Wheel Selection
The Tool Display is always visible and should be used to confirm which wheel offsets and data are active.
All wheel data and dresser data is stored in the tool table. This allows the control to store multiple wheels each with different wheel specs and dresser positions. Wheels are called with the Tool Change call similar to a Turn controls, the first two digits are the wheel number (pocket number) and the second two digits are the tool offsets.
- T0101 will activate wheel #1 and tool offset #1
- T0202 will activate wheel #2 and tool offset #2
There are a few special tool offsets used for Flagging and the diamonds when dressing. The "xx" represents the wheel number.
- Txx91 will activate the offsets for Diamond #1
- Txx92 will activate the offsets for Diamond #2
- Txx93 will activate the offsets for Diamond #3
- Txx95 will activate the offsets for the Active Flagging Device
Use MDI and Cycle Start to select wheel #1 "T0101".
Or on the Calibrate page there are buttons to select a wheel.
Safety Clearances
Safety Positions
Safety Positions are the positions from Machine Zero that the wheel will follow when retracting from the part and moving to the dresser. See Positioning to Dress for more info on the path between part and dresser.
When the machine wheel retracts from the part to the dresser it will follow the following path:
- X will move to the Xsw position
- Z will move to the Zs position
- X will move to the Xsd position
Using the operator panel Jog the machine to different positions and set the position with the yellow TEACH buttons.
When using an OD grind wheel Xsw and Xsd should be set to the same position.
Safety Wheel Clearances
Safety Wheel Clearances define the clearance amount around the wheel when the wheel approaches the dresser diamonds. They can also be used to make the diamond dress passed the edge of the wheel to ensure a clean dress.
Delta X is in diameter mode, so 0.050" would only leave a 0.025" gap between the wheel and the diamond.
Wheel Return Clearances
Wheel Return Clearances define the amount the wheel will back off the part when returning from a dress cycle. This is to make sure the wheel doesn't come in too hard on the part after dressing mid cycle.
In Cycle Settings
- Relieve Amount is the distance the wheel will move away from the last grind in the Relieve G289 Cycle.
- Reposition Feedrate is used in cycles that need to reposition the wheel mid cycle.
- Reposition Clearance Amount is used in the Multiple Plunge Grind cycle when returning the wheel to the start position.
Dresser Setup
- Select the type of dresser that matches the machine. The most standard dresser is #1.
- If dressing a form or taper on a new wheel, enter the desired offsets in the "New Wheel Teach Offsets" box to shift the dress start positions.
- Using the Jog buttons or MPG, Jog the wheel so the circumference of the wheel is just touching the diamond in the X axis direction.
- Press the yellow TEACH button for X.
- Jog the wheel so the Face is just touching the diamond in the Z axis direction.
- Press the yellow TEACH button for Z.
If the dresser type is #2 or #3 then repeat steps 4-6 for each diamond.
- Select the “Tip Radius box, enter the radius size of the dresser point.
Rough Dress
After the dresser is setup a rough dress program needs to be run to true up the wheel before calibrating the wheel to the part. Use the Conversational to create a dress program that will profile and true the wheel. Re-run this program until the diamond touches all the way across the wheel.
See Dress Cycles to learn more about creating a dress program.
Calibrating the Wheel to the Part
Initial calibration of the wheel to the part must always be done if the dresser positions are modified!
X Calibration
- Mount a scrap part into the machine and turn on the Wheel Head and Work Head.
- Using the Jog buttons or MPG, Jog the wheel so the circumference of the wheel is just touching the part and then continue jogging until the wheel has trued up the part and is making contact all the way around.
- Press the yellow Teach X button and then jog off and away from the part to a safe distance.
- Stop the Work Head and Wheel Head.
- Using a precision measuring device, measure the diameter of the newly ground surface.
- Enter the diameter into the Measured X box and press enter.
- Press the orange Update button.
Z Calibration (With One Wheel)
- Mount a scrap part into the machine and turn on the Wheel Head and Work Head.
- Near the bottom of the page is the Tool Offsets group. Type "0.0" into the "Z Offset" and into the "Z Wear Offsets" boxes.
- Using the Jog buttons or MPG, Jog the wheel so the face of the wheel is just touching the shoulder of the part and then continue jogging until the wheel has trued up the shoulder and is making contact all the way around.
- Press the grey Zero Z button near the Z Position DRO.
Z Calibration (With Multiple Wheels)
Follow the "Z Calibration (With One Wheel)" steps on the master wheel.
- Mount a scrap part into the machine and turn on the Wheel Head and Work Head.

Grinding Cycles
Dressing Cycles
Angled Wheel Dressing
The control has two options for compensating the X and Z tool offsets while dressing a wheel that is mounted at an angle. Option 1 - Dress and compensate equal amounts on X and Z axes.
Option 2 - The Z Dress amount and compensation is calculated using the wheel Working Angle from the Wheel Head Setup page.
To use Option 1 copy the following GCode into MDI and run it.
G10 L50 (Start the parameter setting sequence)
N1915 R0 (Set parameter 1915 = 0)
G11 (End G10 sequence)To use Option 2 copy the following GCode into MDI and run it.
G10 L50 (Start the parameter setting sequence)
N1915 R1 (Set parameter 1915 = 1)
G11 (End G10 sequence)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.

% (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)G291: Traverse Infeed Face Grind
G291 works with G277. G291 does a traverse grind starting from X P1 (larger OD) to X P2. The wheel will plunge in on the Z axis each time the X axis reaches to X P1. G291 will grind to a defined Z position, leaving space for an optional stock allowance.
Parameters:
-
- Z: The Z target position to grind to.
- D: The infeed increment that Z axis feeds in by each time the X axis reaches a X P1.
- [A]: The allowance to leave on the final grind position. Defaults to 0.
- F: The feedrate to plunge grind at.
- [H]: The number of spark passes to do after the grind completes. Default is 0.

% (EOB)Measuring Cycles
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.

G232: Recalibration Cycle
Recalibration is typically used for setting the axes to a desired value after in-process gauging (auto-sizing). In the course of the recalibration, the current value of an axis is set to the value given in a macro. In this way,
the difference between the current axis value and the parameter-defined value will be added to the last active zero-point offset.
Parameters:
- X: The Position X will be set to.
- Z: The Position Z will be set to.
- [E]: If E1 is programmed the calibration will be local (valid only for the current grinding wheel), otherwise it will be global (effective for all the wheels)
M170: Wheel Head On
M170 will turn on the current Wheel Head and wait for the Wheel Head On Input
Parameters:
- S: Commanded Wheel Speed (Optional)
M171: Wheel Head Off
